- A total beginners guide about how to adjust the adjustment dial on the JX-Pro grinder.
The difference between the Zero point when the burrs are fully closed and the zero number as the starting point on the adjustment dial. Also how to quickly move the zero number to the starting position on the adjustment dial.
Exactly what I needed. Thank you!! The manual is nowhere near as clear as this explanation. Much appreciated.
Gustavo you are very welcome, really happy it helped.
You are a lifesaver. Been doing research for an hour to find out any of this information and you explained it immediately and so simply!!! Thank you!
Laura you are very welcome, really happy that the video helped you. I have another video where i explain how to calibrate the JX-Pro if you need any help with that. czcams.com/video/yxn0hyFN2t8/video.html
Same here! Thank you so much
Thank you so much for making this video. I only recently found out your channel and started following your videos and was hoping you would make such a one since I am planning on getting the JX-Pro myself and couldn't really understand how the adjustments worked! Keep up the good work.
You are very welcome. I am really happy that you found it useful. The grind adjustment dial and the grind reference chart for the 1Zpresso products can be a little confusing at first. The JX-Pro is an excellent grinder and its very good at all grind sizes, its also got some very nice extra fine adjustments for dialing in the grind size.
Its fast and very consistent and does not have problems with grinding for Espresso using a none pressurised porta filter. I am sure that you will really like the grinder.
Just a fantastic manual! I learnt a lot from this video! Thank you so much!
Thank you also for the positive feedback. Really happy it helped you.
Thank you so much for this video!! I was looking for a video explaining the grind settings weeks and there was nothing at all. This video is a lifesaver!
You are very welcome, i am really happy that it helped you. I also struggled a little with the grind settings when i first got the JX-Pro, so i know it can be confusing. Please let me know if you need anymore help.
Just got my new JX-Pro today and online instructions not all that clear. This was so helpful and clear. Thanks so much!!
Happy to help Tim. Happy new year.
You made this all perfectly understandable. Thank you so much, now I feel comfortable buying one of these.
Thank you Phillip, really happy that it help you. Please feel free to message me if you have anymore questions.
@@mightymightyironhead Thank you
Thanks so much. This is exactly what I was looking for! Very helpful for someone new to grinders.
You are very welcome. The JX-Pro is an excellent grinder.
Thank you very much for this video, great quality, i just got mine today and making me very excited to use it! But then the manual online with grind settings were Soo confusing!! You helped clear it up. I hope you make a video on how to calibrate to zero to factory settings.
Cheers from New Jersey!🙏
Jose you are very welcome. The adjustments are something that can be a little confusing at first, i was also kind of scratching my head at first.
The most important thing to understand is the zero point is not the same as the zero number. The zero point is when the burrs are fully closed and at their most finest point (less than Turkish grind).
The zero number (on the adjustment dial) is really just a reference point to get you started. When you first get your grinder, it will have been calibrated to the zero point (burrs fully closed) but you might not have the zero number at the start.
You might have a different number, maybe 9 or 6 ect. This also confuses some people, because they think that you have to have the zero number right at the top and at the start (under the big dot) but its not so important, you can actually just use any number that you have as though it is the zero number.
1Zpresso do have some information on their Blog page (1zpresso.coffee/calibration/) regarding how to calibrate the zero number by adjusting the knurled thumb nut under the adjustment dial. So this might help you with doing that.
There is a couple of other ways to adjust the zero number also. A the end of this video i adjust the zero number by loosening the adjustment dial, moving the burrs slightly left or right then tightening the adjustment dial again. This can also get the zero number to the start.
Anyway please let me know if you need any help when you get your grinder. Have a great weekend. Cheers from Malaysia.
Thank you so much man! It's all clear now, you are a saviour 🙏🙏
You are very welcome, enjoy your coffee.
Thanks so much! Just received my grinder and turns out it’s a precision piece of machinery… But you explained how it works perfectly!
Thank you Rita, really appreciate your positive feedback. Really happy that you found the video useful.
Feel free to message me if you need any help with your new grinder, i am always happy to help. Have a great weekend.
That's so so helpful thank you. 🙏 Mine is on it's way to me in the post but you've lessened the bewilderment that I may have had when first playing with it. 1zpresso should be paying you! ☕🤓
You are very welcome. The calibration and the dial numbers for the JX-Pro can be a little confusing at first, but once you get your head around how the numbers on the grind reference chart correspond to the numbers on the dial and the rotations, its actually not so difficult.
The JX-Pro is an excellent grinder and in my opinion the cheapest and best all round grinder on the market.
Please feel free to message me if you need any help with the grinder when it gets to you.
Exactly what I needed to get started. Thank you!
Margot you are very welcome. Have a wonderful weekend.
Great video, I'm thinking of buying this grinder and this was really useful. Thank you.
Hi Keith. The JX-Pro is an excellent grinder.
In my opinion its the best all round grinder on the market. Decent capacity, 48mm burrs and importantly its got 12.5 micron adjustment. So its a very decent grinder for proper Espresso using a none pressurised porta filter .
Its a hefty grinder, so if you were planning on travelling with the grinder, i would recommend that you get the cylinder case to carry it.
One thing to note is that the calibration can be a little tricky to understand, but there are links to the 1Zpresso webpage with a lot of helpful information.
Thank you. I don’t know why I was so confused but you explained it the best.
You are very welcome, thanks for the positive feedback. Honestly the JX-Pro calibration is legendary for being confusing so i am happy that my video helped you. Have a great weekend.
thank you for this guide!! truly a lifesaver, i was getting a headache trying to understand the official manual lol
You are very welcome, really happy to help.
Thank you, this was very helpful. I just recently started grinding my own coffee and had no clue how the settings worked. I was grinding super fine until I figured out how to make it more coarse
You are very welcome, really happy it helped. The grinder settings can be a little confusing at first and the information on the 1Zpresso website could do with being a little more clear.
You have 5 full rotations, with 10 numbers per rotation ( 0 1 2 3 4 5 6 7 8 9 0 makes 10 )
To start, make sure that you burrs are fully closed ( zero point ) you can do this by turning the adjustment dial clockwise until it stops. Also make sure that your grinder is calibrated to the zero position, if you are not sure how to do this, let me know and i can help you with that, or check out this 1Zpresso page 1zpresso.coffee/calibration/
You can also check the burrs are closed by either taking the catch cup off and looking at the burrs or by placing the grind handle on the grinder and tipping the grinder sideways, if the burrs are closed the handle wont move, if they are open the handle will move.
When your burrs are closed, you then start to open them, the first rotations numbers are 0, 01, 02, 03, 04, 05, 06, 07, 08, 09 and 0 for your 10 numbers
You also have the three dots in between each number, they are fine adjustments and you can use those for Espresso to dial in your grind size, or even adjust the grind for Pour over if you want to adjust the flavour a little. But i recommend that you stick with whole numbers until you really need them.
On the JX-Pro grind reference chart it looks like this: 0 . 02 . 03 . 04 . 05 . 06 . 07 . 08 . 09 . 1 . 12 . 14 . 16 . 18 . 2 . 22 . 24 . 26 . 28 . 3 . 32 . 34 . 36 . 38 . 4 . 42 . 44 . 46 . 48 . 5
Turkish starts at 08 and ends at 14
Espresso starts at 12 and ends at 16
Aeropress/Moka pot starts at 24 and ends at 3 (30)
Siphon/Pour over starts at 32 and ends at 44
French Press starts at 42 and ends at 5 (50)
@@mightymightyironhead Thank you!
@@MetaNavigator you are very welcome.
@@mightymightyironhead so espresso is 1.2 -1.6 rotations counter clockwise starting from a fully closed (all the way clockwise) setting and then rotating back counter clockwise. Assuming of course that you’re calibrated to a 0 start point. Yea? Thank you!
@@jackesilverdrum yes thats correct. The 1Zpresso grind reference for the JX-Pro has Espresso between 12 - 16, please note that this is just a guide and depending on the beans that you are using and the roast level of the beans, you might have to slightly adjust either way for best results, but it is a pretty good place to start.
If you have calibrated to the grinder at zero point (burrs fully closed and have turned the adjustment dial all the way clock wise) the 0 number should be at the top just under the grey dot.
If you did not calibrate the grinder yet, dont worry about it, just use the number that you have at the top under the grey dot as though it was you 0 number and just count from that number.
Then open the burrs by turning the adjustment dial counter clock wise 1 full rotation (all the way around to the 0 number, or the same number that you start with if you did not calibrate the grinder) that's 10 (each full rotation is 10 numbers).
Then continue turning until you get to the number 2 (12) 3 (13) 4 (14) 5 (15) 6 (16) ect
Dont worry about the small dots between the numbers on the top of the adjustment dial, they are for fine adjustment if you need to further dial in the grind size you can then use those for fine adjustment.
Thank you! This is the best, and also the easiest, to understand.
Thank you Jeanette.
So helpful, first time grinding, thanks.
You are very welcome. Its an excellent grinder.
Muchas gracias!!! Era justo lo que estaba buscando.
Gracias por aclarar mis dudas. :)
I appreciate this video, actually I bought JX-PRO without knowing how to adjust grinding level and I am all set.
Thank you. The grind settings can be a little confusing at first, really happy that it helps.
really helpful, thanks for making this video.
You are very welcome Victor. Have a great weekend.
Спасибо большое за информацию об увеличении помола путем прокутки против часовой стрелки регулировочной шайбы на второй, третий, четвёртый и даже пятый круг(?😃). О том что существует второй круг я уже догадывался, т.к. на клике 9, 4 ( а это ю, ведь,максимальная цифра) помол все равно был мелкий. Теперь я убедился, что думал в правильном нарюправлении. И как разобрать и собрать я просмотрел 2-3 раза ваш ролик. У нас на российских блогах нет такой подробной информации о разборке и сборке этой кофемолки. Сам я начинающий пользователь такими аксессуарами ( ручная кофемолка, медная джезва, гейзерная, иммерсионная воронка и пр.( для потребления кофе и сразу купил ( в кредит) эту дорогую кофемолку. Спасибо, еще раз,брат!
Спасибо за ваши очень позитивные комментарии. Я очень рад, что вы нашли мою информацию полезной.
В этой кофемолке довольно сложно разобраться, особенно если вы новичок. Многих смущает калибровка и то, что означают цифры на регулировочном диске для каждого размера помола, и 1Zpresso действительно не очень хорошо объясняет эти вещи.
Я обнаружил, что можно немного сдвинуть заусенцы, и это изменит число на регулировочном диске, что очень любопытно, и это действительно поможет вам использовать кофемолку JX-Pro, так что вам не придется постоянно снимать регулировочный диск и двигать гайку большого пальца, а затем каждый раз прикручивать регулировочный диск обратно.
JX-Pro - это очень хорошая кофемолка, которую можно использовать и для приготовления эспрессо (без портафильтра). Многие другие дорогие кофемолки просто не могут быть использованы для приготовления эспрессо (без портафильтра), поэтому JX-Pro является очень полезным продуктом.
Я думаю, что как только вы научитесь пользоваться кофемолкой JX-Pro, ваш кофейный путь улучшится на 100 %, но если вам нужен совет по поводу кофемолки JX-Pro, пожалуйста, напишите мне, и я сделаю все возможное, чтобы помочь вам.
Пожалуйста, извините за мои ограниченные способности говорить по-русски, я несколько раз посещал вашу удивительную страну и у меня остались очень хорошие воспоминания о проведенном там времени, но мой русский язык все еще очень плох, так что мои искренние извинения.
Удачи и крепкого здоровья
За здоровье
Thank you , great instructions.
You are very welcome. Really hope the video was useful and always happy when i get some positive feedback. Also thank you also for your sub, very much appreciated.
Thank you! I am a noob and this helps a lot! Cheers from LA
You are very welcome Vinicius. Hope the video helps. If you need any more help, please feel free to message me and i will be happy to help you. Greetings from Malaysia.
Thank you, this has been really helpful
You are very welcome Marta
Just bought the JX Pro grinder and waiting for it to arrive. Your videos about this machine are very helpful - thank you.
Thank you John. The JX-Pro is a very solid grinder. Once you get your head around the adjustment settings, the grinder works very well.
Those 12.5 microns make it very good for Espresso and you have a decent amount of range to play with.
I really hope that you enjoy the grinder and if you need any help with it, please just drop me a message and i will be happy to help.
Really simple and clear explanation!! thanks

Thank you very much, really appreciate the positive comments. Really hope that the video was helpful.
@@mightymightyironhead it defo did ! If you post one on how to clean this thing 😂 think everyone would love it too
Thanks a lot!! I was so confused with the brand explanation 😭😭
Really happy it helped you.
Great great information for the beginner! I was a bit confused even with the manual, so this truly saved my time. Thank you!
Thank you for the positive feedback, really happy that it helped you. Let me know if you need more advise with the grinder, always happy to help.
Thank you! I just got my Q2 yesterday and I had zero idea how to try and do anything with the settings. 🙁 I also did not see a card in my box.
I tried winging it, and had inconsistent grounds and felt kind of stressed and sad. This gives me a new starting point so truly thank you.
You are very welcome. The JX-Pro is a very good grinder when you get your head around the adjustment dial and the calibration.
1Zpresso stopped including the paper grind reference chart and paper manual in the box about 1 year ago. They told me that they did this because of their manufacturing plant having pressure from the Chinese government to use less paper.
If you go to the 1Zpresso website there is some pretty useful information:
1zpresso.coffee/grindsetting/
1zpresso.coffee/calibration/
Also if you need any help with your grinder, please message me and i will be happy to help.
META Coffee thank you for the links. I actually found one of them on my own but it wasn’t easy. And the second one I hadn’t come across. -Their little QR code in the box brought me to a page that wasn’t particularly helpful.
I’m actually quite frustrated that companies have stopped including even the most basic of instructions and helpful things inside of the box.
Because then it’s on the consumer to print things out or to have to dick around with their phone to try and find stuff and/or print if you even HAVE one. (like instant pot, I just wanted a simple chart of how to make basic things like friggin rice. But they want you to go their whole ass website and even then it’s not a simple thing to look up. There’s “recipes“ but by different people and you’re not even sure which ones actually WORK.)
Anyway, we are here about GRINDERS! Lol. Thank you for your kind offer. 🙂 I actually have one question for you. I’m not sure if my Q2 is grinding properly… I mean the action is fine, but I am not sure what the grounds are supposed to look like. This is my first grinder. The individual pieces don’t look as consistent as I thought they were supposed to. (But they definitely don’t have gigantic boulders in them like my Electric did.) HOW consistent are the grinds supposed to look from coffee? I got the impression it was supposed to be pretty literally identically sized. But maybe it’s not.
OR, is this the breaking in process? OR, are grinders supposed to have a sort of calibration of the burrs if something is out of whack? (A different kind of calibration from the link you sent.)
The scientific mind in me thinks to buy a whole Nother grinder from a different brand to have more experience, and get a better idea over some of these ideas and see if grind size looks the same or different… But honestly financially I should NOT do that.
So any feedback and advice and knowledge you can throw down, it would be so greatly appreciated! ⭐️
@@lurklingX you are very welcome. I totally agree with you about the paper grind chart and manual. I am actually a dealer for 1Zpresso and i remember when they used to include these things in the box. I was really disappointed when they told me that they wont be including them.
But honestly even with the grind chart and manual their information was (still is) pretty difficult to follow. They even updated their website to improve their information about one year ago, but its can still be pretty confusing for someone who is just starting out and needs a very basic guide.
And then on top of that, its not convenient at all to have to download the grind chart to reference every time you use the grinder. I even started to print off cards myself at my own cost for my customers because i think that its really important that they at least have the grind chart.
I think that some of this confusion is down to often simple mistakes. For instance, when some people talk about grind adjustments and they say "its 21 clicks" this does not help at all when you have a grinder that has numbers and also fine adjustments in between those numbers and all of them make a clicking sound when you move the dial.
So i think that a lot of the time people talk about these products and they don't actually have the product, or they don't really know how to use these products, they have just heard other people say these things and they are repeating that haha
Ok lets talk about your Q2 grinder.
The Q2 is a very basic Pour over grinder with 36mm stainless steel Pentagonal (5 cutting head) burrs.
Its got 10 numbers per full rotation, with 3 clicks (fine adjustments) between each number. You have 3 full rotations that covers your full grind range. That's a total of 30 adjustments.
The grind consistency with the Q2 is not too bad, its got 36mm stainless steel burrs and 5 cutting heads, so grinding anything finer than Pour over ( 18 - 24 ) will take a little more effort.
However even grinding finer for Aeropress, Moka pot ( 12 - 18 ) and Espresso ( 06 - 12 ) is obviously going to take longer and be more effort because its a lot finer than Pour over grind size.
However regarding particle consistency.
Even the best grinders in the world can not get every particle the same size and shape, there are literally thousands of particles of all shapes and sizes every time that you grind your beans. The type and size of your burrs will make a difference to the speed of grinding and the consistency of the particle size. Bigger burrs ( 48mm ) have more cutting heads ( 6 or 7 ) and a bigger surface area, so they tend to be faster and more consistent.
Finer grind should not be noticeably inconsistent the same way that you can really see when more course grind particles are are inconsistent, because the particles are bigger and you can see them more easily with the naked eye. Finer grind tends to have more fines and not boulders.
This type of grinder usually gets less consistent the more course you go, so Pour over is usually passable, but French Press can often be inconsistent.
You are correct that there is always a short burr "seasoning" period when you first use your grinder. This is because the blades cutting edges are still very sharp and this sharp edge is not the best for cutting the beans. After maybe a few hundred grams the burrs should be a little more dull and cutting at their best.
Its pretty difficult to say if your grinder is not working properly without seeing a picture of the grind. If your ground beans look really wrong, i am confident that you would know that there is obviously something not right there.
The Q2 does not really have any calibration stage, you assemble the grinder and screw the adjustment dial on, turn the adjustment dial all the way until the burrs are fully closed and that's your zero point. Whatever number you have when you can not turn your adjustment dial anymore is your zero number to start. So if you have the number 3, that acts as your 0, if you have the number 6, that's your 0, so whatever number you land on, you can not change that with the Q2.
If you have dismantled the grinder to clean it and reassembled your grinder properly, you can cross that off the list.
Lighter roasted beans and harder processed beans (SHB) can be a problem, because (SHB) beans are quite dense to grind and lighter roasted beans have not developed in the roaster long enough and are very hard and brittle, this can make the grind particles more inconsistent.
In my experience the Q2 is not the most consistent grinder, because it is a pretty basic grinder with smaller Pentagonal burrs. Its about as consistent as the Timemore C2. However its still quite good for a cheap manual grinder and i would not say that the consistency is terrible.
This is a link to my Facebook page, if you have time please send me a picture of your grind beans and i could say with a little more certainty if there is a problem with your grinder: facebook.com/metacoffee178
Very clear. I have been doing all wrong before👏🏼👏🏼👏🏼👏🏼
Really happy that it was helpful.
This is super helpful.
I was a little surprised to find NO INSTRUCTIONS inside the box. YES, I know there’s a QR code to a website. But the website instructions weren’t that instructive, to be honest.
For the price (I paid £140 for mine on Amazon) they might have at least included a quick start ‘basic’ guide.
The manufacturer claim this is to save trees. Wot a load of bull squirt. (a) they could have used 100% recycled card for the guide. And (b) have you SEEN how these things are packaged? Half a forest of heavy card boxage, then a metric shitload of everlasting foam.
Sorry. Got a bit rantey there.
So anyway. Thanks again for the info. It’s much appreciated.
You are very welcome. 1Zpresso actually updated their website to improve the information about their products, including a picture guide for calibration right after they stopped including the paper manual and grind reference chart, but its still pretty confusing and whoever they paid to translated the information into English needs a kick in the nuts.
I think that its the calibration that really throws people and 1Zpresso dont really do a good job of explaining the calibration though adjusting the thumb nut.
Its also not so easy to understand the difference between the zero point and the zero number on their website, so that can throw some people also and believe me i have spent a lot of hours explaining to people about these things.
I will give 1Zpresso credit for addressing these issues with their new X-Pro grinder. They have totally redesigned the adjustment dial and the thumb nut so that it take literally seconds to calibrate the grinder.
I never bought the "saving trees" excuse either, like you also pointed out, the rest of the packaging is not very "environmentally friendly" and plenty of other companies get their products manufactured in China and they still include paper work the box and i think that this is more to do with cost cutting, plain and simple.
Very helpful. Thank you
You are very welcome Michael.
Very helpful, thank you!
You are very welcome Jose.
Great explanation, so easy to understand. Thanks so much. We owe you a BIG jar of coffee 😀
You are very welcome Paul and thank you also for your positive feedback. Really happy that the video helped you. Have a great weekend.
I'm so jealous of your funnel support and main body support alignment. Mine is in a weird position and make it a little tricky to add coffee beans to
Arian it was pure luck that i have the top ring that has that alignment. I used to have another top ring that was kind of nearly in a cross and was also quite difficulty to get the beans in without pop corning. But i gave the top ring to someone else who dropped their grinder and damaged their top ring.
Then i ordered some new tops rings from 1Zpresso and mine is now in that alignment. I am not sure if all the newer top rings are like this, but its worth keeping an eye out about this. It could be that the newer top rings are all like this.
@@mightymightyironhead I actually bought mine recently. I think it is pure luck. Thanks for the great content.
Thank you Arian, appreciate your support. Stay safe and well, drink more coffee.
Thanks exactly what I neeeed
You are very welcome, really happy that the video helps. Have a great weekend.
So useful. Thank you
You are very welcome.
Спасибо, добрый человек🙏
Привет, Александр, Я очень рада, если моя информация вам помогла.
you're a godsend
Thanks for the video I had a hard time getting to zero, I removed the adjustment dial nut and 2 other nuts below to adjust and it was very hard for me to press down on the burr + putting them back tgt at the same time. I'm going to try your method the next time I dismantle the grinder to clean!
Also may I check with you, say if the adjustment dial is already turned clockwise at it's maximum tightness, but at the inner ring of the adjustment dial, there's still some allowance (meaning you can still see the inner tracking lines above the last nut), is it normal? Or is this correct? - I have to turn the adjustment dial till its inner tracking are all screwed in. Cause from my grinder, I can still maybe see 1-1.5mm of inner trackings when I look at it from the top
You are very welcome, i am really happy that my video helped.
I think that sometimes the burr shaft can be hard to push down when you want to take the burrs out of the grinder, the space around the burr shaft is very small so that the shaft does not move when you are grinding.
The other parts that you remove from the grinder are in this order:
1) adjustment dial
2) knurled thumb nut
3) Upper bearing cap
4) Upper bearing
5) Sliding column
When you turn the adjustment dial all the way clockwise, you should be able to fully close the burrs (zero point) you will know when you are at zero point when you feel some resistance and the burrs dont want to turn anymore.
I highly recommend that when you start to feel the resistance with the adjustment dial that you do not try to turn the adjustment dial anymore, it will be pretty obvious that you should not turn anymore at that point.
The problem is that you might not have the 0 number at the starting position, this is very common. 1Zpresso have some information about how they recommend that you fix this by adjusting the knurled thumb nut.
I personally found this method did not really work for me, but you can find that information through this link: 1zpresso.coffee/calibration/
Go to the parts that reads: Top Adjustment
JX-Pro / JE-Plus
When you reassemble your grinder, its very important that everything it tightened properly. The top ring (the top ring is the ring around the very top of the grinder with the grey dot) can sometimes become loose and if the top ring is not screwed on properly, the rest of the parts wont screw on properly, so make sure that the top ring is tightened properly (again dont over tighten or you wont get it back off again).
Then make sure that you are pushing the burr shaft up into place. This is important when you screw the knurled thumb nut back on. If the knurled thumb nut does not turn all the way until you hear the last click, its not on securely and the adjustment dial wont screw on properly.
If you have tightened everything properly, it is normal for you to be able to see about half of the threads from the sliding column sticking up about the top ring.
If you push the burrs at the bottom, you will see the parts move up even more, so this is normal and it will help you to then be able to screw the adjustment dial on without needing to push the burrs up with your other hand.
If you have done all of these thing correctly, your grinder is ok and there are no problems.
thank you good sir
You Sir are very welcome.
Thanks a lot.
Thanks!
You are very welcome.
You are a lifer saver, thank you very much! Two questions, first are these numbers just for the 1Zpresso or they are referring to some form of measurement. For example if i go to a coffeshop and ask for coffee grinded at 2.0 will it be the same as the 2.0 of this grinder or every grinder has different settings? Also what are the clicks that everyone talks about in hand grinders?
You are very welcome, really happy that it helps.
The numbers in my video are only specific to 1Zpresso JX-Pro grinder, these numbers will also be different for the other 1Zpresso grinders. This is because each 1Zpresso grinder has different sizes and types of burrs. Usually Espresso grinders like the JX-Pro have 48mm conical burrs and they have smaller step adjustment increments than a Pour over grinder, Pour over grinders might also have smaller size burrs.
The JX-Pro has 12.5 microns adjustment and the 48mm conical burrs give it a wider grind range, so the grinder can dial in the grind for for Espresso pretty well if you find that your extraction is too fast or too slow and you need to finely adjust the grind size to get the extraction perfect.
The JX-Pro can grind from very fine Turkish grind size up to French press grind size. The adjustment dial has 10 numbers ( 0...1...2...3...4...5...6...7...8...9... and back to 0 ) on the adjustment dial and a possible of 5 full rotations from the Zero point (burrs fully closed).
The first 0 up to the first full rotation will be very fine (Turkish grind) after that, the more rotations you open the burrs, you will have Espresso, Aeropress, Moka Pot, Drip, Pour over, French press ect ect untill the burrs are fully open. An example would be for Pour over you might need 26, so from the zero point (burrs fully closed) you turn the adjustment dial from the 0 number all the way around 2 full rotations ( each rotation has 10 numbers, so thats 20 ) and then continue turning until you get to the number 6, thats 26.
Each full rotation of the adjustment dial has 40 Clicks. In between each number on the adjustment dial you have 4 fine adjustment clicks ( 0....1....2....3....4....5....6....7....8....9.... 0 )
These clicks are not the same as numbers, they are for fine adjustment increments. Say for example you are making an Espresso using a None pressurised porta filter and the extraction is a little too slow or a little too fast, you need a very small adjustment to make the grind size a tiny bit bigger or smaller, if you dont have these (fine adjustments/smaller microns/clicks) you wont be able to adjust your grind size accurately and your grind adjustment will be too big or too small.
There is a kind of universal system for grind size for coffee and its something like this:
Extra Coarse Grind (cold brew grind)
Coarse Grind (French press grind)
Medium-Coarse Grind.
Medium Grind.
Medium-Fine Grind (pour over grind)
Fine Grind (espresso grind)
Extra Fine (Turkish Coffee Grind)
But there is no grind settings or numbers guide for individual grinders and their grind settings, so if you went to a coffee shop and asked them to grind the beans for you to 2.0 they wont know what to do unless you told them the name of the grinder that you are referencing, then they would need the grind reference chart from that specific grinder to get a basic idea.
You are better off asking them to grind for the type of brew that you are using, if you are brewing Pour over, ask them for a standard pour over grind size, Aeropress, Moka Pot and Espresso (using a pressurised porta filter) are all just about the same size. Its when you get to Espresso using a none pressurised porta filter that it gets very tricky.
Also bear in mind that different beans, different roast levels, water temp, tamping pressure and other factors will often mean that you might have to adjust your grind size, so the ground coffee from the coffee shop might not work as well as you want.
@@mightymightyironhead WOW thanks for taking the time to explain all this to me! I really appreciate it, your channel has just won a loyal fan 😀
@@ElectTheChopStick you are very welcome, happy to help.
Really if you don't have a grinder and you still want to buy fresh roasted coffee from your coffee shop.
Just tell them what type of beans and roast level the beans are and what brew method you are using.
If its Espresso, tell them what machine you are using, they should know if its a pressurised porta filter or a None pressurised porta filter. Aeropress, Moka pot, Pour over and French press are a little more easy to deal with.
With that information they can usually get pretty close to something useful.
Thank you!!!!
You are very welcome. Have a great weekend.
👍 thanks
You are very welcome.
Whenever I grind my espresso at 14, it gets stuck in the portofilter. I have to move the grinder all the way to 22 to get a useable drink. I followed your calibration instructions too. Any ideas what I am doing wrong?
Hi Qais. Sorry but when you say "it gets stuck in the porta filter" do you mean that the coffee puck gets stuck in the porta filter? Or do you mean that the coffee is so fine that it blocks your machine?
The grind size that i used in my video might not be accurate for the beans that you are using. Also the grind reference chart for the JX-Pro is just a rough guide to get you started and you would need to adjust your grind size depending on the type of beans that you are using and the roast level of the beans also.
Dark and light coffees have different solubilities and as such will extract differently.
Lighter coffee will typically need a finer grind for best results and finer grinding increases surface area, which helps with extraction.
Dark roasted coffee is less dense and has a lower moisture content due to the extended roasting process it’s been through. This means you’ll need a slightly coarser grind overall to achieve the same extraction.
This is also why that sometimes your puck is a little less dry when you have finished your shot and you try to tap the puck out of the coffee basket and its too wet to tap out.
Light roasted coffee is denser and has a slightly higher moisture content than dark roast, which will affect solubility in the other direction and make extraction a little more difficult. A finer grind compensates for that.
However you also said that you needed to change the grind size from 14 to 22 to get a shot, so i think that you are saying that you are blocking the (Picopresso?) again this seems like a really big change in grind settings, but this can be normal depending on the beans again.
I have has the same thing happen to me a lot. I has something like 15 - 16 for my last shot, then i change the beans and i then needed to change the grind size to something like 18 - 19 or even more like you.
The porta filter that you get with the Picopresso is a slow flow basket, these baskets are designed to allow you to use a cheaper grinder with bigger grind settings (larger microns) slow flow baskets are kind of in between a pressurised porta filter and a none pressurised porta filter and the shape of the walls are not straight like a normal none pressurised porta filter.
The shape of the walls on a slow flow basket are designed to move pressure to the middle of the coffee basket and help with getting a shot if your grind size is a little too course (similar to the way that a pressurised porta filter works with its one hole) so its not unusual to need to grind a little more course using a slow flow basket like the one with the Picopresso.
I personally would not worry about this, if you get a decent shot at 22 and the Espresso tastes ok, then its nothing to worry about, the grind size is the correct grind size is the grind size that allows you to get a good shot and this can and will change depending on your beans, roast level, tamping and water temperature.
You could also check your dose, Wacaco recommends between 16 - 18g so weight your coffee and maybe drop the dose down a little and this will allow you to also grind a little more fine.
Another thing is your tamping. Always use the dosing ring when you are tamping, this will really help you to not ever tamp, some people say that they tamp and the take the dosing ring off and then tamp again, but this can cause issues and block the machine if you are not careful.
anyway i hope my information help you and like i said, i dont think that you need to worry about using a bigger grind size as long as you get a decent shot use whatever grind size works.
even tho i just buy timemore c2, i already looking for an upgrade (planning to just give c2 to my mom)
i think i found it now... jx pro is the best choice. i already looking for comandante c40, but when i look it its just too similar with other timemore product (c2max).
I personally would recommend something like the C2 to people who are just starting to explore pour over, aeropress, and Moka pot coffee, its a decent first grinder for those things. But its not for Espresso (maybe if you use a pressurised porta filter you might get some ok results).
A lot of companies advertise their grinders as being "Espresso" grinders, but they are not really Espresso grinders. They simply don't have the fine adjustments needed for real Espresso (None pressurised porta filter) and at best, you might get something in the Medium / fine grind range that's ok for an Espresso machine that uses a pressurised porta filter.
You can tell a lot about a grinder by the type and size of burrs it uses. However the first thing to looks for (for me anyway) is the micron size and fine adjustments, that will tell you if its a proper Espresso grinder or not.
Comandante also market the C40 as an "Espresso" grinder. But they neglect to tell you that you also need to pay an extra $60 - 70 USD for the RedClix burrs before it can get anywhere near the fine adjustments needed for proper Espresso grinding. The C40 is a nice grinder for Pour over, Aeropress, Drip, Moka pot and not bad at the course end for French press, but its not an Espresso grinder.
The JX-Pro is nearly half the price of the C40, its very consistent at all grind levels with very few fines. Its very fast (20g of medium roasted beans in under 30 seconds) its easy to use and easy to maintain. Its got 48mm stainless steel burrs and most importantly, its got 12.5 micron adjustments and enough fine adjustments to dial in Espresso very well using a none pressurised porta filter, so right away you have a proper all round grinder that actually does what it is supposed to do..... and its less than half the price of the C40 with the RedClix burrs.
Hello i need help with the right setting on the jx-pro for pour over, what is your preference
Hi Boris. The grind settings for Pour over on the grind reference chart for the JX-Pro are from 32 (3 full rotations and keep turning to the number 2) and 44 (4 full rotations and keep turning to the number 4) so you have quite a decent grind range for Pour over.
The perfect grind size will obviously depend on the recipe you are using, the type of beans and the roast level of the beans that you are grinding and water temp also, so i am sorry that i can not give you a precise number to dial in, but i recommend to just go for something in the middle and then adjust from there.
@@mightymightyironhead i have read the chart. That's more than 40 different grinds. I was hoping for something more specific.
Hello, I got mine today. You said that factory settings for grind level is "zero point" I want to check how it feel and try turn it clockwise and I didn't feel the resistance until I do a full revolution. Is it normal behavior? This indicates that my factory setting was at 10, not 0.
Hi David. When you get your grinder the 1Zpresso team will have set your grinder to the zero point.
This is basically just the burrs are fully closed, you can test this by attaching the grinding handle and holding the grinder sideward, the grinding handle wont wont move.
Its very typical that you will need to calibrate the grinder and get the 0 number to the starting position on the adjustment dial.
You do this by removing the adjustment dial and then adjusting the knurled thumb nut underneath a couple of clicks at a time until the 0 number moved into the correct starting position.
@@mightymightyironhead I really appreciate your reply. So out of the box the mill is set to "0" but it's only the number. In my case I could still turn the whole clockwise revoultion until the burrs are fully closed and match the next 0 position. After the full revolution did I feel resistance. I meant this - so this is normal? Thanks! :)
@@Wlodi6223 sorry i am not so sure about what you are trying to say. Are you saying that the 0 number is in the starting position ( right below the grey dot above the adjustment dial ).
But you could still turn the adjustment dial another full rotation before the burrs were fully closed?
If so, this is nothing to worry about, it just sounds like the grinder was not calibrated or the burrs closed and set to the zero point in the factory.
Usually when you take the grinder out of the box for the first time the burrs are fully closed ( zero point ) and you can not turn the adjustment dial any further when you turn it clockwise.
It is possible that they did not do this in the factory, but i have never had any feedback about this from any of my customers, so i think that this is not common.
Also the 0 number on the adjustment dial is not always calibrated by the factory team and at the staring position under the grey dot above the adjustment dial.
A lot of people get confused when they turn the adjustment dial all the way clockwise ( to close the burrs ) but the 0 number does not line up with the grey dot at the top.
If this happens, you will need to calibrate the grinder by adjusting the knurled thumb nut under the adjustment dial to get that 0 number in the staring position, this is pretty normal.
@@mightymightyironhead perhaps my words as a beginner coffee drinker were not understandable to you, but I found in your answer what I was looking for. Thanks for your solution and patience!
@@Wlodi6223 no problem Dawid, happy that you found the answer.
How do you know you have tightened enough that "that" is the zero point?
Hi Yoshiro. I personally turn the adjustment dial clockwise until i feel some resistance, you can actually feel the "bite" where the adjustment dial is getting tight.
Then i gently turn a little more until the adjustment dial feels tight enough that it feels like you are forcing it if you turn it anymore, it will feel obvious at that point.
If the burrs are fully closed (zero point) place the grinding handle on the body and hold the grinder sideways, the grinding handle will stay still and wont turn.
If the burrs are not fully closed, the handle will turn (fall) when you hold the grinder sideways, if this happens, take the handle off and gently turn the adjustment dial a tiny bit more.
I didn't expect this thing to be so complicated! Where do the beans go in??
The beans go in the top Nic.
I feel like a didnt reassemble my grinder back correctly. I did the adjustment cause people have experienced issues when first getting the grinder. I watched a previous video on how you used 1 rotation at 5 clicks for the wacaco picopresso and figured thats great that you gave a reccomended setting. However, when I dialed in that setting I got pretty corse grinds. So I don't know whats going on.
I dialed at 9 clicks and got a better grind, but this is far from a full rotation and 5 increments.
Leo please elaborate what you mean when you said that you think that you didnt reassemble your grinder correctly?
Also please elaborate what you mean when you said that people have experienced issues when first getting the grinder?
I have not heard about people having issues with their grinders, other than not understanding how to use their grinders.
In my video, the settings that i used where good for those particular beans. Actually i was using some medium roasted beans and medium roasted beans are more difficult to dial in the grind size, darker roasted beans are more easy.
However like i said in my previous comments, your beans will be different to my beans, so your grind settings with not be the same as my settings. You settings wont be a lot different, but they might be up to a few clicks different.
Will you do any JX adjustment and zero point tutorials too? Thank you and its very helpful 👍
Actually i am planning to do a quick video very soon about the JX grind adjustment settings. I will also explain a little about the difference between the JX-Pro and the JX adjustment dial.
@@mightymightyironhead Thanks a lot! Will wait for that :)
@@user-dg1oj2dw3c you are very welcome.
@@mightymightyironhead - Hey META - this/these JX videos still coming?
@@scottaigner2389 yes i am thinking of more useful video's to make for the 1Zpresso grinders. Please let me know what you would like to see and i will be happy to look at that.
Is it recommended to clean hand grinder burrs with urnex tablets periodically?
Hi David. I highly recommend that you never use water or anything else that requires water on your burrs, this can really damage the burrs.
Urnex ( CAFIZA TABLETS (E16) are really for back flushing Espresso machine tubes, or cleaning porta filter group heads ect it requires water to use this product.
Without being technical, stainless steel burrs have tiny imperfections and holes on the surface and if water gets into these spaces it can cause spotting and even rust.
So i really recommend that you never use water to clean your burrs.
@@mightymightyironhead thank you for your reply. The urnex tabs I was referring to are made of grain and are for cleaning grinder burrs. There is no water involved with these tablets, they are different from the descaling tablets made by the same brand.
@@davidnonomura1975 my apologies, i understand what product you are referring to now.
Urnex make the Grindz tablets for cleaning burrs and you are correct they dont need any water to work. Apparently they are all natural food safe, plus gluten free.
I honestly dont see that they would be a problem to use, they look pretty easy to use. I am not really sure why you would need to use something like this though, the tablets are pretty expensive, around $30US.
A good regular clean with a cleaning brush and a blower is usually enough to keep your burrs in good shape.
I suppose if you use a lot of dark roasted beans that are oily, the burrs would need a little extra.
But even then there are cheaper options, i personally grind some oats to help get rid of any excess build up of oils or odors, quick cooking oats work pretty well. However you do need to brush the particles off after you have done that.
@@mightymightyironhead Thank you! That sounds a lot easier than disassembling the grinder every month or two and losing all my calibration and settings. And oatmeal sounds like a great alternative! What a great idea.
@@davidnonomura1975 you are very welcome. I found this link to a video for the Grindz tablets, it explains how you use them: czcams.com/video/7sNRzQqfSzc/video.html
The disassembly, cleaning and maintenance is not that difficult for the 1Zpresso grinders.
The JX-Pro can be a little tricky to re-calibrate back to the zero number, but other than that, they are not so bad.
The oats can work quite well if you use darker roasted beans and they become a little oily, they dont leave many particles behind and they are none corrosive and odorless.
Then you just need to purge the burrs as usual with some beans and you should be good to go.
Got a coffee grinder with aliexpress. From 1 to 9 clicks clings with one side of the millstone. And with only 10 clicks, it scrolls without touching. Do you think this is a marriage? In my opinion, the shaft is not even! I thought from the first click there should be free rotation if everything is well centered. I haven’t ground coffee yet and hasn’t taken apart. I don't know what to do, whether to return it to the seller or not.
Can i please ask you what grinder did you buy, was its a 1Zpresso grinder and if so, is it a JX, JX-Pro ect?
When you get a 1Zpresso grinder the grinder is set to the zero point in the factory ( the zero point is when the burrs are fully closed ) this is the finest setting ( finer than Turkish grind ) because the burrs are so close together that they are just about touching. This is 0 ( zero point ).
The JX-Pro has: 10 Numbers / 40 Clicks per rotation / 4 Click per number. So one full rotation looks like this ( 0....1....2....4....5....6....7....8....9.... and back to 0 )
When you say "From 1 to 9 clicks clings with one side of the millstone". do you mean that the burrs are touching ( clings ) from the number 0 up to the number 2 ( 0....1.... this would be 9 clicks )
And then you say "And with only 10 clicks, it scrolls without touching" 10 clicks would be ( 0....1.... 2 ) are you saying that the burrs are touching ( clings ) and only stops touching ( clinging ) at 10 clicks ( 0....1....2 ) 2 full numbers from the zero point ( burrs fully closed )
You are correct the handle should move freely after opening the burrs one click. Obviously if the burrs are at the zero point ( fully closed ) the handle wont move. But as soon as you open the burrs just one click they will move freely.
If the handle is not moving after opening the burrs from 1 to 9 clicks, i would say that there is definitely something wrong with either the burrs or the adjustment dial.
What grinder did you get, Who did you get the grinder from?
@@mightymightyironhead Coffee grinder 1zpresso JX Pro, bought at Aliexpress. It looks very solid and according to the seller's assurance the original! Yes, you understood correctly from 0 .... 1 scrolls tightly, and from 1 .... 2 .. slightly clings. And only 2 ... approximately, free speed. THOSE. switching to the first point from zero there is no free wheeling. And the free play should be at the first point from zero, if I understood you correctly? Today I talked to some of the owners of this model from Ukraine. They say this is supposedly allowed because we are talking about microns. I don't know how true this is. Your experience was also interesting to me!
@@user-ll1qd2rr9p when you turn your adjustment dial all the way clockwise as far as it will allow, the burrs will be closed completely (zero point)
You can then put the grinders handle back on the grinder and turn the grinder on its side. The handle will stay in place and not move, because the burrs are closed and wont allow the handle to spin.
My JX-Pro handle wont move freely until i open the burrs about 4 numbers from the closed position (zero point) for instance.... if my burrs are fully closed (zero point) and the adjustment dial has the number 1 to start, i need to turn the adjustment dial about 4 numbers more until my handle moves freely.
The Ukraine users are correct, because really nobody is going to grind anything at at the zero point, its far too fine for any type of brewing. Even the Turkish grind starts at 08.
One more thing is that a lot of people simply can not agree on what is the zero point. When i close my burrs (zero point) and then open the burrs a couple of clicks, because i don't want the burrs to be touching and as you point out the size between each step (microns) is so small that its ok to do this and not worry about it.
@@mightymightyironhead Quote: My JX-Pro handle wont move freely until i open the burrs about 4 numbers from the closed position (zero point) for instance .... if my burrs are fully closed (zero point) and the adjustment dial has the number 1 to start, i need to turn the adjustment dial about 4 numbers more until my handle moves freely. End of quote. By the number 4 for the free wheel in your coffee grinder, you mean: 0 .... 1 .... 2 .... 3 .... 4 do I understand correctly?
In my case with a zero point, like yours, the millstones are not closed to the limit (I also think this is superfluous). They are compressed so that I cannot turn the shaft with my fingers, but if I put the handle on, that is (due to the lever) a tight move.
By the way, yes, I did the procedure with rotation on my side holding on to the handle, as shown in many videos) ... The free move is quiet and pleasant. No imbalance is felt. Neither visually nor tactilely. If on cheap coffee grinders you directly feel how the shaft is walking, then everything is very good here!
@@user-ll1qd2rr9p yes its normal to have that situation.
From closed burrs (zero point) open the burrs from about 4 numbers ( 0 .... 01 .... 02 .... 03 .... 04 ) and the grind handle can move smoothly.
Even at 04 numbers, this is still well below any grind size that you would use ( Turkish starts at 08 ) so its nothing to worry about.
Please do one of these for the K series.
Hi Ryan. I was thinking about doing that very same thing. Hopefully i will have the video posted very soon.
Hi Ryan. Here is a link to a video i made about the K series adjustment: czcams.com/video/ifyvCZenxw8/video.html
I'm from Brazil and really need the help of this video. Too bad it doesn't have subtitles in Portuguese so I could understand and calibrate my 1Zpresso. 😞
Hi Renato. Sorry for the lack of translation options.
Maybe i can explain a couple of things that might help you to understand the grinder.
The "Zero point" is not the same as the 0 number on the adjustment dial. The Zero point is basically when the burrs are closed.
To do this, just turn the adjustment dial all the way clockwise until the burrs are closed.
When you turn the adjustment dial all the way until the burrs are closed (Zero point) and the 0 number does not line up with the grey dot, dont worry about that, just use whatever number you have as if it was the 0 number.
If you want to know how 1Zpresso advise people to calibrate the 0 number, you can go to this link and it explains in words and pictures.
1zpresso.coffee/calibration/
Geralmente, o ajuste superior compartilha o mesmo conceito com o ajuste interno de que os números no mostrador são projetados para contar quantos passos você deu e, portanto, o ponto de partida não será necessariamente no # 0. No entanto, se desejar definir o ponto de partida como # 0, siga as etapas abaixo:
Etapa 1. Quando o ponto apontar para # 1 / # 2 / # 3 em vez de # 0 no ponto mais justo, simplesmente remova o botão de ajuste (girando-o no sentido anti-horário).
Etapa 2. Ajuste a porca serrilhada no sentido anti-horário em 1/2/3 cliques.
Etapa 3. Volte a apertar o botão de ajuste e o ponto inicial deve estar em # 0 (± 2 cliques).
The 8-12 setting is for turkish, actually. Espresso is 12-16. Although on mine the 16 setting is so fine it plugged up my espresso machine.
I just got a decent grind at setting 20. I think they changed something on new models. I had an older one that was just right at the 12-16 setting.
Yes thats correct the grind range on the 1Zpresso grind reference chart for Turkish is 08 - 12.
However it is just a reference chart and its not 100% accurate. I think that those 8 numbers below the start of the Turkish grind range could be used to adjust finer if needed.
I was curious about why there was 8 numbers between the zero point and the start of the Turkish grind range when i first started selling 1Zpresso grinders and i asked 1Zpresso about this.
They also said that its for slight adjustment of the grind size and also "to make room for the tolerance range" so make of that what you will.
1Zpresso did change a couple of things a while back with the JX-Pro around about the time that they changed from the red dot to the grey dot on the top ring.
I noticed the the adjustment dial was tighter right away, i think that they changed the bearings on the top ring (dont have an old red dot top ring to check though) I dont really remember of the top of my head what they said about it, but i will look for my old correspondence with them and see if i can find it.
@@mightymightyironhead the handle fits tighter on my new one, too.
@@aurtisanminer2827 the actual Hex fitting, where the burr shaft fits into the handle?
I cant really remember what the older handles felt like, but i know that 1Zpresso do have a small magnet fitted inside the Hex hole at the end of the grind handle now.
It could be this that makes it feel like the handle is tighter.
@@mightymightyironhead yes, that part. The hex on both ends is actually machined to tighter tolerances, too. The older handle wouldnt fit over the new shaft when I tried, so dimensions are slightly different. The older shaft’s hex also had rounded corners on it while the new one’s corners are sharp. It was neat to be able to compare them directly side by side like that. The changes would be difficult to notice otherwise.

Burs are at 4 and 9 out of the box. Not zero.
Hi, sorry i am confused. “Burrs are at 4 and 9 out of the box” The burrs can not be at both numbers, so i an not sure what tou are trying to say?
Its not unusual when you take the grinder out for the firat time to find that the grinder is not calibrated, so tour grinder is obviously not calibrated and you will have to do that.
1zpresso included a stupid advertising sticker with my grinder, but they couldn't print out a basic chart that I could stick on the fridge? So idiotic.
Its interesting that you received a sticker with your 1Zpresso product, i was not aware that they are including stickers in the box.
When i first started dealing with 1Zpresso, they included a really nice grind reference chart card and a card manual in the box.
They stopped doing that and just include a card with an QR code to scan that takes you to their website to then have to find out where this information is, i was really disappointed when they did that and i even started paying a company out of my own pocked to print the chart up and i give that away for free to my customers.
When i asked 1Zpresso why they stopped including the paper card and manual, they told me that is was something that the Chinese government were forcing manufactures to do to cut down on industrial paper use.
But i suspect that this is BS, because i also import quite a lot of other products from China and i also deal with other companies that produce their grinders in China and they all include the proper paperwork, so i suspect that this is a cost cutting measure and nothing less.
Extremely unhelpful! How to set the zero point to begin adjustment is most important factor.
That's correct, you need to set the zero point (burrs fully closed) before you set the zero number (0 number on the dial in the starting position).
Not sure what video you were watching, because that's exactly what i show in this video.
Its ok, no matter how many times i explain this, some people just never really get it. You could always go to the 1Zpresso website and see what they say about it.
