That was the best video explaining the hot end and clogs and jams I have ever seen on CZcams. Respect Sir !
Wow.
I consider myself kinda experienced in 3D printing including print head management with complete reassemble time-to time for various reasons, including clogs/jams. And I think this video is awesome! It even provides some information outside of my previous knowledge.
Agreed! I had no idea there was so much involved in the hot-end. Amazing explanation!
I agree. I learned more about hotends in this 10 minutes video than I have learned over the few months I have spent trying to troubleshoot clogs.
Agreed! just watched 40 videos and finally found this one which solved my problem. Thank you!
"ever seen"???
Are you by any chance the parent of the video producer?
I love the 3D printed hot ends - great visual
still relevant today, worked for me.
6 years in and now at 12 printers, had my first jam today. AWESOME video man.
where can i buy this guys luck!?
I know this is 4 years old, but still this is the best I've seen from my extensive searches.
You literally saved me on this. I got a clog in the heat break which was causing my prints to stop after about an hour of printing. And, because I took the whole thing apart and fixed that, I have not had an issue with the thermal runaway either. So just by fixing the clog, I have (fingers crossed) fixed the other issue as well.
Thank you.
This was the most explanatory and in depth explanation I have found. I really liked the cross sections that you printed because I have been doing 3D printing for years but never actually knew how the hotends worked. Thank you for making this a available resource for all having this issue!🙏😃
ironically your prints have under extrusion lol
Nothing more can be said : this video has EVERYTHING. One day, if 3D printing is taught in class, this will be a video shown to the students. Thank You.
6:25. Thank you. For 3 months my fans had switched cables ;( you helped me to realize that heat sink fan should kick in at 50 degrees, and not print fan. Ufffff let's start serious printing ;)
I watched 3 useless videos before I found this and you helped more in 10 minutes than all those others combined. Thank you sir, I'm back up and running on all my printers.
I've just started 3D printing and already had my first clog I think. Been searching around forever for a good explanation and this has been by far the best I've found. Thanks!
My 3D printer has been just taking dust for almost 6month because of this exact problem waiting that i decide myself to buy a new hotend. It seams i can just clean it, brilliant. Thank you !
One of the best Videos about 3D-printing i have ever seen - and i saw a lot. Congratulations!
You saved me from buying and replacing the hot end on a v2 all together. Thank you for the video
This actually works! To sum up, if you have a micro-swiss or clone, disassemble and reassemble w/thermal paste between the hot block and nozzle, and the heat sink and heat break, but NOT between the heat break and the hot part. It really works!!!! Thank you!!!
This is not just for hobbyist. Academia research also encounter these issue quiet often. Thank you for your well explanation.
Good pictures are worth more than 1000 words. These are great pics. Thanks.
Thank you for this video. I am new to 3d printing, so when I got the jam in my hotend your video helped me so much to get it unclogged.
Thank you for your thorough explanation of the problem and process. It is what I needed.
best breakdown I've seen in awhile. thumbs up .
Your explained the topic very well..the best part is the cross section model you have printed in order to explain in more practical way..
Hi Joe. Clearest descriptions of nozzle/extruder fault vectors I've ever seen. The visuals (prints) nailed it! Nicely done. 👍
(Hope all is well with you. Happy New Year, Susi xx)
You could not have been more clear when explaining this annoying issue we have all faced. Super, super helpful
I am glad this content is still relevant till this day. Just clogged my good ol Ender
300 hours or so. Survived that long until I had to follow your advice! Well now I have a growing ecosystem of tools to support my printer lol. Had to open up the circuit board on my generic pyramid a1 printer to reattach some heat sinks from the drivers too.
you damn legend, perfectly explained even after 3 years. thank you.
loved the cutaway hotend models. Great tool to help explain to new hobbyists. Well Done, Joe!
Very nice and clear explanation and down to earth for us none technical. Thank you so much.
If I may add on the V6 hotend, the jam normally happens on my 3d printer on the ptfe tube after the heatbreak . The heat during the print will soften the teflon tube eventually , then during the retraction the melted plastic will go up there and unable to move back. This is the reason why the higher temp teflon tube is best for this application. My fix for this problem on my bondtech style extruder with v6 hotend is I use 2mm ID aluminum tube with ptfe sleeve on the outside, from the heatbreak to the lower part of the extruder. This fix works for me, no more jams since I made this fix. I also do this fix to my IDEX printer and so far so good. This is now my go to fix for v6 hotend.
Thanks, this video exactly diagnosed our ender 5 problem, we got the parts, cleaned, and fixed it in an afternoon.
Amazing resource. Thank you!
filament jam on first day in
dealing with major frustration on christmas morning here. I hope to follow these tasks and clear my printer out tomorrow.
Thanks for the video
Very good. And thanks for the cut away views. I found a way to keep the Bowden tube from fatiguing the push to connect fitting. I print a washer (of sorts) that has a flat bottom and a rounded chamfer on the bottom, and a hole with a 45 chamfer ID on the top. The rounded chamfer on the bottom helps to fit snug in the heat sink. The 45 chamfer on the top is to ease filament insertion, while the hole is just big enough to pass the expanded filament being unloaded. The PTFE tube is cut flat on both ends and sits between the washer and the nozzle. Now here is the trick in setting it up. Insert the washer and the push to fit connector to the top of the heat-sink. Bottom the push to fit connector and then back off two hex sides (1/3rd turn). Insert the PTFE tubing into the bottom of the heat break. Use the end of the heat break as a cut guide and cut the tube with a good razor blade, making sure to get a clean cut that is flush with the bottom of the heat break tube. Reassemble the hot end as normal saving the tightening of the push to connect fitting for last. Do NOT over tighten. Now insert the Bowden tube into the push to connect fitting. I also use the premium tubing for the heat break and the rest of the tubing can be what ever. Now the retractions will not stress the fitting. There is a flat positive seal between the nozzle and the heat break.
I'll add one more tip for the Mk10, when seating the PTFE tube leave the nozzle a little loose, push the tube all the way in until it hits the nozzle then tighten the nozzle to ensure a nice tight fit against the PTFE tube. About a half a turn does the trick for me. If you leave the nozzle too loose it will bend the PTFE tube and cause jams so don't over-do it.
Thank you so much. Your models helped the visualization. Cheers!
Crisp and clear. Appreciate your effort. Keep going.
Brilliant support! Thanks, as ever.
Hi. Noobie here who's just had his first jam. Your video has helped me enormously. Thanks for uploading. I'll subscribe for future videos now too :)
Excellent explanation. The first video that really explain how it works.
I’ve been printing for a couple years now and still learned something from this. Thanks
Awesome video! New to all of this and had my first major clog last night. Your cutouts of the hot ends really explained everything!
I have to agree, simple no drama and to the point! Explained like I didn't know and now I do! Thanks!
Thank you so much for this video i wasn't able to print for week! But this helped :)
Thank You! I really did enjoy this video. Really great work. I have been 3D printing a long time and faced all those issues many times but even then I really enjoyed watching it.
It's funny I watched this a 2 days ago thinking I almost never get clogs I'll forget about these great tips before my nozzle clogs again.
2 days later I get a partial clog and I'm like this is some kind of revenge for saying I never get clogs. lol
Great visuals, they made a very informative video that was easy to follow and understand. I wish I had seen this 2 years ago when I started 3d printing it could of saved me a lot of headaches! Great work Joe!
Outstanding video!!! Easily one of the most informative that I have seen. The two cutaways were perfect for helping me to better understand what goes on inside the print head, and to diagnose the problem I was having. Thank you for all the effort that you put into creating this video! (Subscribed!!!)
Nice video. Thanks for your effort. Always good to visualise the problem.
Excellent video! Very well explained. Thanks!
i love you, i was about to buy all new parts because i couldnt figure out the problem. youre the man thank you thank you
Thank you very much, this kind of dedication is commendable.
You are the light. Thanks man.
Brilliant and comprehensive, as always. Keep the awesome quality my man!
This video is must watch now for 3d printing newbies.
Absolutely brilliant with that cross section, you saved me many hours trying to understand and fix my blockage!!
so amazingly thorough and easy to understand
Very detailed. Thank you so much! I’m new to this hobby and this will help me immensely! Thank you for taking the time out of your day to make this video!
Sometimes to clear out a heatbreak I remove the nozzle, fan and heatsink (in my Anet A6 the extruder heatsink is removable), and turn the hotend on to max temperature, and leave it like that for a few minutes. This works if you either do not have a heat gun, or you can't be bothered to disassemble everything to avoid blowing on plastic parts. So far I only needed to remove the heatbreak twice- one time I overtightened it and it broke off, and once the PTFE inside started to negatively affect prints by being worn out from printing a lot of cheap ABS that needs temperatures between 240 and 255 °C as opposed to 230 which some people seem to recommend.
Absolutely amazing video. Thank you so much
Thank you so much! That was seriously helpful
You've just earned a sub within the first minute, already seeing the hotend printed models I knew I was in for a great explanation!
I've been trying to troubleshoot my Ender 3 for the past few days and I was unable to determine the exact cause, but the visualization with the PTFE tubes led me to the right source of the problem, thanks a lot!
Incredible explanation!! Amazing
(UPDATE BELOW FIXED)
I don't know why I didn't watch this video sooner. I've been looking through scattered information on this topic for over a week now. If I had seen this earlier I would have progressed a lot faster. I keep getting jams mid print. (It's really frustrating when I see one print finish and another fail misprint) But now that I can see what goes on inside the hot end. I believe I should be able to diagnose what's happening. Just throwing out a bunch of solutions to a possible issue is just frustrating and a waste of time. Your video actually showed me and explained what the issues are and how it should actually run. Thank you!!!!
UPDATE: Got it working! Interesting this video helped me realize there wasn't a problem with my hotend. I did trim the bowden tube to make it more flush. However, I was finally able to stop focusing on the hotend and look at the extruder where I found the real culprit... the ridged metal part meant to feed the filament was missing one screw! So I found a spare and tightened. So far so good!!
This was so incredibly helpful!
A pearl of useful information. Learn a thing or two. Thank you Joe. I understand better now why I had a jam recently and how I can prevent it.
Awesome. Thanks for sharing. I will be coming back for more.
Holy crap! This is a fantastic explanation and I loved the cross section! I absolutely had the last issue just because I didn't know what the inside of the heat sink looked like.
Now I both understand what happened (how I was stupid) and was able to fix it in 2 minutes! Can't thank you enough for the video and explaination!
Hugely helpful video, sir! I'm dealing with these problems right now. Thank you!
Thanks for the info you shared !
Thank you so much, I had a clog right up to the Bowden tube. I really liked the 3d models you used to explain all the parts of the extruder unit. Great video.
I cant believe it took this long for me to find a good video on clogs, great job and thank you!
After 5 months I finally had to come back to this video and it helped so much, thank you!
You are the man. I think you just helped me figure out why a used Ender 3 pro I bought keeps clogging. I've done many cold pulls, replaced the nozzle, and replaced the PTFE tube. You're comment about the heat sink fan not cooling as efficiently as it could tipped me off. When I turn the fan on after it's been off for a few hours the heat sank fan screams like a banshee for at least the 1st minute or two. This has me thinking even when it comes down noise wise it still may not be spinning as fast as it should.
Very good presentation - Thanks!!
Thank you so much! I've been pulling my hair for a couple weeks. This made it so easy to fix my colgged hotend!
Damn that explanation was 10/10, high quality content
This!!! I needed this!!! Three hot ends later, you've come to rescue me!!! Thank you!!!
This explains a problem I had with my printer perfectly! Great explanations
Very good demonstration!
Really very good hot end models and discussion. Kudos!
At last, a simple straightforward video explaining extruder problems. Big thanks
Great clear info, no fluff. I watch most tutorials at like 2x bc most people sucks at getting to the point. You kept every second full of useful info. Keep up the good work!
I know the video is so old but its really solve my skipping problem by cold pull and clear. Thank you so much for advice
Perfect and complete guide! Thank you!
This was amazing. the crossections really helped with the information thanks
EXTREMELY helpful vid, detailed, concise, and very well done. Huge thank you!
Amazing explanation! Im at my wits end and you just answered every question I had!!! Thank you!!
Absolutely brilliant video thank you
Amazing explanation! Thanks.
Wow, superb video! Very clear, concise, great visuals. Keep them coming!
Absolutely awesome video and clear explanations. Thank you so much
What a great video. Explanation is one of the best I have seen on the subject.
Thank you ! Very well done video.
Great 3d printing troubleshooting video! Thank you Sir!
A breakdown explained that makes sense. 👍🏼👍🏼
Thank You very much for the support! Great job :-)
Yes, it has been covered a billion times.. But never as clear, comprehensive and insightful as this.. Thank you!
Fantastic guide. I have a stock v10 hotend that's clogged and I was so frustrated I just bought a new one. Glad I ran across this.
Excellent description of the "killer-problem" I had this night with my printer after about 3 days of usage. This video is really best help. Now my Ender is working again. Thank you!
Love your use of the 3d printed hotends for demostration:)
