Ender 3 upgrades: EZR to direct drive adaptor and all in one rear mounted electronics case
Vložit
- čas přidán 12. 06. 2019
- I’ve put some hours into CAD this week, designing two upgrades to improve my Ender 3 that you can benefit from too.
The first is an adaptor to join my two favourite Ender 3 extruder mods together: the direct drive kit from Basaraba Innovations and the EZR extruder. This simple part gives reliable and convenient filament loading, with improved printing performance.
The second aims to tidy up my electronics, which were accessed underneath the printer and had buck converters and other components loose. I’ve created a modular system for mounting the electronics at the back of the machine, to suit the standard Creality board, an MKS Gen L or an SKR 1.3. There are also mounts for TL smoothers, a raspberry pi, a buck converter and two relays. The cooling fan is now much quieter and can be upgraded to a 40x20mm design without issue.
All parts are easy to print without support and fit on an Ender 3 bed. This should be compatible with the standard Ender 3 and the Ender 3 Pro.
I'm really happy with my design and I hope others can benefit too.

Hey I wanted to say you make wonderful videos and they help me very much but I was curious the teaching tech sign in the background have you done a video for that and how to make that as I would love to see how 3D printing integrates with electronics with that sign
idk tho, no direct cooling on a stepper motor drivers ehhh.
We meet again...
I've watched several of your videos on the Ender 3 series, some over my head technically, and I wanted to say 'Thank You'. You have been so informative and helpful. Kudos to you for all the hard work you've done for the 3D printing community. Excellent work and thanks again.
That has got to be one of the cleanest looking Ender 3's I've ever seen
I just finished printing and installing this. Great case. I was concerned with air flow but now that it's all setup the electronics are cooler than before. Thank you for the great design!
Just did this, loved my EZR and glad you did the legwork making it fit with the DD kit. Thanks for designing the spacing bracket piece. Love your channel!
Thank you for that great design of the rear cases. The fits perfectly. I install it with the skr 1.3 on my ender 3. Very good video!
I don't know why I've never discovered your channel before now, I can't stop watching your videos.. keep up the great content.
This looks brilliant! I I can't count the times I've flipped the printer over to access the MKS board that I installed. I love the way you've fit the Raspberry Pi in with the other electronics.
I've always been critical of upgrading something to the point where you are replacing it but this is probably the best and most practical upgrade I've seen. I wouldn't be surprised if Creality either contact you or rip this design. Very pro.
Fantastic additions to the Ender 3!!! I'm definitely thinking I'll be upgrading the board and using these parts. That looks so much nicer than factory!!!
Thanks
This is amazing Michael, excellent job, as usual. I actually was having similar issues flipping the printer upside down to check on stuff. I look forward to your new guide!
Your creative solutions and easy to follow guides are awesome. You are awesome.
After watching so many of your videos over the past 2 years: Big thanks for taking the time and effort! Helped me a lot with my first 3D printer (Ender 3) and still does :-)
Thanks for being objective about the topics, good background info research and providing good starting points for my own decisions!
Two notes about the "old" Ender 3:
The y-axis stepper motor has a different mounting than yours, so plugging in the cable is really hard.
The cable for the stop switch (z-axis) is very short, so I had to switch with the y-cable
-> With the v4.7.2 replacement or original Melzi board.
Finally a decent case for my SKR. Thanks for putting this together Michael I cant wait to print it. :)
which one do you have?
Absolutely fantastic job with this all-in-1 design. I have purchased Skr v1.3 and I will be setting up and installing soon. I must print your all-in-1 box first!
Awesome video yet again. I love your videos you do such a good job with them, very good summary at the beginning and then perfect level of detail and a great wrap up. I've done a lot of the modifications you've described including this one on all of my enders and they went so smoothly. For the commenter who said you need to get paid I totally agreed which is why everyone who appreciates your hard work should become a patron supporter like I did. Keep up the excellent work!!!!!
WOW!!!!! that's all I got. ........'Thank you so much for your hard and detailed work!
Cheers Mike!
Amazing, Once again, you have solved a major issue for me. I have an Ender 3. Between the BL touch Pin 27 adapter, the raspberry PI and now the latest...the buck converter for the Noctua, I have run out of places for things. This will absolutely be the next project. Thanks.
When I saw the thumbnail: "nah, I'm not going to upgrade my printer any further"
After watching the video: "THIS IS SO COOL I NEED THIS"
This is so good thank you for taking the time to make this! With the SKR 1.3 you can use the second serial to talk to the raspberry pi (Octoprint) with a couple of jumper wires. I can't wait to print this and fit it. Thanks again!
What a great mod for the E3. Well done, Michael.
This is super awesome Michael. I was looking for a different solution for my MKS and I think this is it. Fantastic job!
You and Chep are becoming my only 3D printer channels I go to for help. Thanks! Oh and the DD3 kit is no longer available.
This is super impressive! It's such a better design than stock - I know what I'm printing this weekend!
Damn I love your channel :)
Thank you for everything you do for the 3d printing community!
A great mod Michael. I don't have a n Ender 3 but I love watching your mod videos. They have helped me a lot with the upgrades for my Anet E10. I currently have my E10 installed on a Ikea lack table with all the electronics underneath, but I don't like the fact that I have to tear the whole thing apart to work on it, so I'm looking at doing something similar to for it. Thanks for sharing
You sir are not just a great educator, but a fine engineer as well. Well done. Since you have a second unmodified Ender 3, might I suggest a comparison between the two showing the thermal performance of your case vs the stock one.
Just got a Ender3, was looking for exactly this. Thank you for what you are doing.
Ordered the TH3D EZBoard as a replacement for the standard, printing this now so its all ready when the new board arrives, great design
Outstanding as usual, Michael.
Struth Michael, we owe you so much for the helpful videos. You really have enabled us luddites a chance to better understand 3D printing.
Good Stuff. LOVE THE DESIGN!!! I just got an Ender 3. I'm learning as I go. Love your channel as well!!! Thanks for posting.
Very elegant solution Michael, well done!
Wow you really have outdone yourself this time. Brilliant work 👍
FANTASTIC!!! - A very well thought out mod, thanks for sharing.
So this is probably my 3rd time watching this video at 3 different levels of interest. When you first published it, I was but an avid lurker interested in 3D printing, I watched it again to realize that I love how much the community enjoys modding their printers, and I too have that bug. Today I watched this as a suggestion after watching you upgrade to the direct drive mod and I have a SKR E3 Mini 32 bit board ordered from ali express that I'm waiting on. I think I am still going to print these parts because after having modded my printer to use a 5V Noctua fan (using the same 5v pins on the ICSP header that everyone uses for the BL Touch), now the loudest fan is the 4010 on the board, which I might as well put in the back of the machine :D Basically, your channel is awesome and that's what I appreciates about you.
how is that skr e3 mini going?
@@pieter-6385 I absolutely love this board. I am running Marlin 2.0.1 and it is quiet af. Definitely suggest printing a direct drive mod as well.
Jeez dude - you earned a like and subscribe. lots of work in the design, print and the schematics. Thank you
Wonderful solution!!! I was searching for something like this!!! Now I can clean all the electronics cable nest under my printer 😋
Good job on the design of the case, Michael. Much nicer than that hinged thing you came up with before
Top work Michael, epic piece of design... time to start printing! :-)
Love the case mod. Can't wait for the SKR1.3 VID
Wow! Really clever design! Cheers!
What a coincidence! I just started designing my own rear mounted case a few days ago and now almost got it completly working...
Wow. Really good job. I had the same issues with the case in front, but now much better. Thanks!
Beautiful work Michael!
Thanks for the information. I have a Ender 3 still in the box. It's many years old since it's 2023 now. I need space to set it up.
You are doing great job! Very nice videos and quality guides
Freeking Brilliant..thanks for sharing your efforts Michael.
This is hella smart. Great job. I'm definitely doing this with mine.
you make some of the best parts for ender 3, tyvm
HOLY CRAP! Why aren't you on the Ender design team dude? This is gorgeous!
Wow this is an amazing project here. I printed the 2 rear pieces and they fit Amazing.
Wow, this is lovely. Now I know what I’m printing tomorrow
I just printed the project and will be installing it Tomorrow. I think you've done a wonderful job in putting it all together. The only thing that I feel should go hand-in-hand with this mod is a new set of cables. The original ones are just too long and clutter the case too much. But it's nothing, that a day with a crimping tool would not fix :) Thank you for this great mod!
I've had my EZR setup as direct drive for months now. I made my own mount for it. Works great! Wish I could post pictures on here.
you can upload pictures to site like IMGUR and then just post your link here :)
Really nice design that. Great job 👍🏻
Great job Michael. Thanks for sharing and best wishes.
This should fit for the SKR 1.4 too, guess I found the perfect case for my Ender 3 Pro electronics
Thank you
Nice solution.
Along with relays for power switching and so on that you're planning, it would be interesting to fit some thermal sensors on critical components and connect to the Pi for monitoring, to see how well the cooling works out.
Magnificent. Pimping out my ender 3 pro with this for sure.
This is an awesome mod, thanks for sharing!
Superb design. You could also use some of space in front to mount the screen to reduce the printer's footprint. Watching your parts slide into place was extremely satisfying, haha.
This was almost going to be delayed but fortunately the final design iteration fitted together perfectly. I was pleased.
I’m waiting to see a video on the Zesty Nimble. Great work and designing as always.
They are out of stock but when this is fixed, my Ender 5 will get one.
Teaching Tech I’m waiting on mine right now, hopefully it will arrive by July. They’re waiting for flex shafts and more gears.
And I just got done designing a full case like that for the front. Never thought of moving it to the rear. I'm kinda partial to mine since it doesn't require cramming wires into a short case and allows for better airflow. Thanks for the great videos and innovative ideas.
Would love an stl from you if you upload it anywhere - Im a bit concerned with the airflow in this one as well.
@@RonnieLaugen Sorry I take the summer off from 3D printing and stuff to do summer activities and I didn't see your comment. Back at it. Still haven't finalized the design as the fan isn't fitting. Don't know if it's my design or my printer. I'm still new at the Thingiverse stuff so I will try to figure out how to upload it. I draw in autocad, not sure what file type you need/want. User name PE_RN. hopefully soon.
That’s a beautiful setup
Great job, Michael! I am tempted to get rid of my mess under the printer. Will wait until you release the skr video though! :)
WOW, that looks great but for one thing. I'd keep an eye on the heat of the stepper drivers, think you'll find the fan is pulling more air right next to it through the Pi hole (pun sorta intended ;) ) as air, like water, will always flow with least resistance and that is always the closest location to vent. Other wise it looks awesome! Oh, seems there is some room behind the board, what about a blower style fan that blows in and directly along the stepper fins...?
I stand by what I commented below. The only issue that came up was that I couldn't plug the y-axis stepper back in on my regular Ender 3 with the motor oriented as stock. I ended up rotating the motor 90 degrees, so the plug now faces back rather than down. This way I also won't need to unplug it again to move the boards out, if that's needed. Thanks again for this great mod.
This is so great. Thank you so much for the great work.
thats a neat and tidy way to do this, it looks easy to access too... I took a different approach, as I wasnt keen on flipping the machine upside down to tinker with it, I used the original tin box but moved the electronics box fan to the front after carefully cutting a hole for it, covering the original hole by re-positioning the sticker on the lid, then printed an internal mount for the gen L , as well as a spacer for the lid to give me a bit extra height for the heatsinks of the 2130's, unfortunately this leaves no room for anything extra inside, so I got my extra bits on printed brackets at the rear of the printer, not the neatest solution - so I may have a look at this - thanks again for sharing
Loooove that mainboard mod. Gotta do this soon 👌🖤
Great video! Thanks for the spacer.
Utterly brilliant. Thank you for this.
Ha! That was very timely. Lately I've been considering making exactly that so I can fit drawers at the front space - with your MKS Gen L case I couldn't get a drawer to fit there due to the USB cable getting in the way.
That's great, now I can add another drawer to the front to store more tools n stuff in
If you have an ender 3 pro I made one up already. www.thingiverse.com/thing:3708057
just found this one,impressive, one thing i would have liked to have seen for the genL setup would have been the addition if wanted to use either the 2.8 or the 3.2 tft
That's a really clean idea!
Good work ,looks nice and tidy
just subed love your channel...you have help me alot.thank you....going to upgrade my board soon,I will use you guide.once again thanks man.keep on helping people
This is an amazing post and is incredibly well done. Great job I agree with Regular Guy! Gotta join your Patreon group!
Fantastic build. I ran into one issue. Running the SKR Mini E3 2.0. My Z Stop cable was not long enough. I swapped cables for the Z and Y stop. Problem Solved!
Just in time! I was about to make your previous upgrade! This is awesome Michael, thank you
WoW.... super great design!!!
the only thing it needs now is a mounting point for that cable chain everyone uses!
There's a remix for that ;)
@@Neerie79 STL ?
I JUST added the Gen L with your custom housing, and the TFT from your video. Welp, time to take the ender back apart! Lol.
Love the design of this and will probably be printing it myself for when my EZBoard Lite from TH3D arrives, but like a few other people I'm concerned the cooling might prove insufficient. Would love to see some tests versus the stock solution, and tests without a Raspberry Pi (tape the hole closed) and see if it's even a concern. Not doubting your expertise, it'd just be great for everyone's peace of mind!
That's an elegant solution. Almost makes me wish I had gone with the Ender 3 rather than the 5, lol.
awesome work man
Really looking forward to the SKR video - hopefully it offers better temperature stability than the main rival!
mike306dt
My MKS Gen L works much better after I added a capacitor to the 5 V rail. That was enough to knock back a lot of the noise, and get the temperature sensing to work more effectively. There are still occasional spurious ‘heating failures’ thrown up, so it isn’t a 100% solution yet.
I used a 2200 uF capacitor, attached to the 5 V block in the corner. The other terminals in that block I used to run a 5 V case fan, which may be one source of noise on that rail.
I also had a ton of luck by desoldering the 22uf cap from the original creality board and using it to replace the garbage one on the MKS board. My temps got rock solid again after doing that. And the best part is its free just need to know how to work with smd parts. The MKS board has the wrong type of cap on it from the factory on the output side of the voltage regulator.
@@boggisthecat Thanks so much for taking the time to reply, I did try a 5v capacitor (low ESR Panasonic at 1200uf iirc) but it still twitched around somewhat!
@@Potatogambit I don't think my soldering skills are good enough to remove that little tiny one - that or I don't have the confidence to do so! I'm surprised TT didn't have the same issue - but I did wonder whether he has the Mean Well psu which in theory could be a lot less noisy than the stock ender 3 (non pro) version?
Thanks for your reply, I may look at doing this mod after I've found something else to learn on!
mike306dt
If you have an oscilloscope and a few capacitance values you can try different combinations to draw down the various frequencies. Unfortunately these are just cheap boards with some poor quality components, so what worked for me may not work for you. (Also, my 5 V fan doubtless changes the noise profile.)
Some people reported putting two 1000 uF caps on the 5 V rail in the corner and at the servo output 5 V pin. I’m dubious that this would make much difference, but if you have two 1200 uF or similar then you could attach a second in parallel initially, or on one of the servo 5 V pins.
After you get done with all the testing and mods, you should make a video about what all you would recommend doing, and a brief overview of the setup?
This is one of the most amazing mods for Ender 3 in my opinion! I'm only a bit concerned about the possibility of insufficient efficiency of the fan to cool down some hotter stepsticks like TMC2100 and now there's no camera cable for the Pi but other than that it's just great!
You can get much longer camera cables for the RPi. If concerned about the internal temps, add a temp sensor on each side and connect them to the RPi, then ssh into the RPi to check their status. Plus, of course, have the RPi send you an alarm if they get over-temp.
this was my concern aswell so i adapted the lid and installed a 2nd noctua fan to work in tandum force airflow ive had some 200 hour prints have have yet to suffer from any blemishes caused by stepper drivers over heating
clarestevens2 have you got the stl for that bud
Impressive design
Well done you !!
Thanks for sharing :-)
I'd say you want to look at moving the fan to a vertical mount, pushing out the back, rather than down onto the workspace, the intakes are fine where they are.
You should print some storage cabinets to fill the space in the front
a very nice job ! Thanks for sharing!!!
I would love to see you install an E3D Cyclops with an MKS Gen L and TMC2130s.
Michael, greta idea for a rear box.
One little thing, I would have put the new 3d printed end cap at the rear and used one of the original rear end caps at the front to tidy things up. Then you would have no unsightly screws showing.
Looking forward for the video about relays - I assume they would be used to cut power after print stops, but how the raspberry and relays would be powered then?
The pi stays on all the time. The main reason people want to kill power to the ender when not in use is the noise the fan makes. Upgrading to a noctua hot end fan will take care of that. Also, less risk of fire of the hot end turns itself on/doesn't turn off. You can do this without a pi as well. You can wire a relay that's switched on and off by a limit switch placed near the top of the Z-axis and tell your slicer to send the hot end all the way up to the top when it's done printing.
Great video and thanks for spending the time to design and build the parts. I do wonder if that cooling setup is actually going to work. Have you measured the heat sink temp on the MKS drivers? I doubt they would have much air flow going over them. I’d be more inclined to have the fan over the main board rather than with the raspberry pi. Or maybe run a fan per side.??
Hi! Great mod.. One question though, where did you find the STL for the zip tie holder on the Z motor? Can't find it anywhere
