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.
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!
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.
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.
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)
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!🙏😃
I needed this detailed explanation of jams and clogs. My printer has started having these problems more and more lately and now I know the “why” and best way to fix and minimise it happening again. A really helpful video. The props were fantastic. Thank you.
Still the best explanation 4 years on! Fixed my issue and highlighted the root cause. That being that when it initially became blocked using ABS, the feed gears on the Bowden feed became clogged and the filament was chewed out preventing the filament from being fed into the hot end. simply removing the filament with feed gear marks from the spool ensured the filament made it to the hot end. Increasing the temp also ensured smooth flow from the nozzle with a noticeable increase in extrusion diameter. Cheers!
Absolutely perfect explanation. You saved both of my 3d printers which had similar heat creep issues, and going through each of your recommended steps recovered BOTH of them. Thank you!!!!!
more people should watch this.... i loved it. I do not even have a problem and also knew this before, but this video is so great for beginners with cheap printers/parts. Doing this stuff since years but boy, that is the best video about this topic!
Awesome, this helped me. My cooling fan wasing blowing on my hotend. I was changing nozzles, hotends, checking my extruder, finally figured it out. Thanks!
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!
This is a very professional and informative video. Thanks for not only showing how to resolve clogging issues but what tools are needed to make the job easier.....the next time.
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!
Just had to unclog my hotend and thought I check if I took all the right steps. I must say, this is the best video regarding this topic I've seen so far! Great visual aid, clear explanation and actually showing how it's done. Big kudos!
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.
AWESOME content! I've been suffering with clogs and jams like every couple of prints. This helped me to fully understand how my hotend should've been assembled, what is probably causing the clogs and jams, and how to fix it properly.
Thank you for an excellent video. I have been happily printing for 1 1/2 years, changed to a Micro Swiss hot end and immediately got a jam. Never had this issue before, I change nozzles regularly so did not need to clean them. I've been reading that linear advance may be helpful if I'm using an all metal hot end, as well. Many thanks for all the helpful posts on this thread!
Thanks, this helped me diagnose "creep" up the hot end that had been annoying me more so long. This was so well explain that immediatly I was able to diagnose my problem. The 3D models where super visual tools. Thank you again!
Wow that was brilliant. I have been having issues with my Creality hot end and your video has just solved them. I would never have thought to check the PTFE only how tight the nozzle was. Many thanks for a very informative video.
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
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!
I got my 3D printer about a year ago. Sure enough, swapping filaments caused a jam. This video was very helpful! I really liked the cut-away models and they helped me understand better how to take care of the issue. I have to wait for some new Boron Nitride thermal paste to reassemble my hotend. But I was able to remove the jam with the help offered here!
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.
Hi, Thank you for saving me a ton of time trying to pull the hotend apart, your tip with removing the nozzle and pusching through all the stuff in the heatbreakc really worked wonders.
Brilliant! Been struggling for 2 weeks with no filiment on the bed, thought it was a leveling problem. Just pulled a huge clog out of the heatbreak, thank you sir!
Great video just helped with filament not feeding halfway through print. feeder was skipping. The pipe needed to be pushed right upto the nozzle which stopped the blockage. awesome thanks
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!!!
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.
Thanks! This helped me take care of my first clog. I didn't even get one thing printed before I had a clog, so I was frustrated. It's all going and I'm a lot happier now! I hadn't seen the concept of pulling the tube out and cleaning from the top which is what ultimately cleared it!
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!
2 days into my 3D printing career, I got a clogged nozzle. This video helped me understand the why and how to fix it. Thank you for helping out us newbies.
Excellent idea to do this for the new comers to 3D printing...but ultimately you made it so much educational that even "senior" 3D printer can enjoy it ! Congrats !!
This vid was super helpful and I was able to clear the clog in my system as a result. Thanks! You've earned a sub. Love the 3d printed visual aids too, cool stuff.
Dude thank you so much for this, I thought there was an issue with my hotend but after going to town with the needle the filament started to flow freely again! Bless!
Cleared out my first clog using a video from Creality, but this video really helped me understand everything that's going on. The visuals were fantastic for helping make this digestible and fun to learn about :)
thank you! I bought a 3d printer used a while back and just got filament for it and I definitely have a jam. hopefully with this new knowledge I'll be able to finally to do a test print
Thanks, this video was very helpful. I'm printing since a few years but never had such a massive jam like today. Normally a cold pull does the trick - but not today. The trick with the push stick (which I had from my retired Geeetech printer) did it. Didn't even need the the heat gun :)
That was the best video explaining the hot end and clogs and jams I have ever seen on RUclips. 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
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!
One of the best Videos about 3D-printing i have ever seen - and i saw a lot. Congratulations!
I know this is 4 years old, but still this is the best I've seen from my extensive searches.

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)
best breakdown I've seen in awhile. thumbs up .
6 years in and now at 12 printers, had my first jam today. AWESOME video man.
where can i buy this guys luck!?
@@Takeoverytcommentsyes my brother I resonate with this

Good pictures are worth more than 1000 words. These are great pics. Thanks.
Thank you for your thorough explanation of the problem and process. It is what I needed.
I am one year into 3d printing and this video is great and still current it helped me unclog and rebuild my hot end. Thank you
I needed this detailed explanation of jams and clogs. My printer has started having these problems more and more lately and now I know the “why” and best way to fix and minimise it happening again. A really helpful video. The props were fantastic. Thank you.
loved the cutaway hotend models. Great tool to help explain to new hobbyists. Well Done, Joe!

Crisp and clear. Appreciate your effort. Keep going.
This is not just for hobbyist. Academia research also encounter these issue quiet often. Thank you for your well explanation.
You just help me understand and solve all the issues ive been having as a 3d printing newbie. THANK YOU!
more people should watch this.... i loved it.
I do not even have a problem and also knew this before, but this video is so great for beginners with cheap printers/parts.
Doing this stuff since years but boy, that is the best video about this topic!
Cool idea to print the extruder block cross-section!
You saved me from buying and replacing the hot end on a v2 all together. Thank you for the video
Perfect! Thank you very much!
Awesome, this helped me. My cooling fan wasing blowing on my hotend. I was changing nozzles, hotends, checking my extruder, finally figured it out. Thanks!
Absolutely brilliant with that cross section, you saved me many hours trying to understand and fix my blockage!!
I have to agree, simple no drama and to the point! Explained like I didn't know and now I do! Thanks!
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!
This is a very professional and informative video. Thanks for not only showing how to resolve clogging issues but what tools are needed to make the job easier.....the next time.
Yes, it has been covered a billion times.. But never as clear, comprehensive and insightful as this.. Thank you!

Thanks, this video exactly diagnosed our ender 5 problem, we got the parts, cleaned, and fixed it in an afternoon.
You could not have been more clear when explaining this annoying issue we have all faced. Super, super helpful
I’ve been printing for a couple years now and still learned something from this. Thanks
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..
Nice video. Thanks for your effort. Always good to visualise the problem.
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.
After 5 months I finally had to come back to this video and it helped so much, thank you!
Very nice and clear explanation and down to earth for us none technical. Thank you so much.

i love the cross-sections best video ever thank u so much
Love your use of the 3d printed hotends for demostration:)
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
Really very good hot end models and discussion. Kudos!
Thanks, this helped me diagnose "creep" up the hot end that had been annoying me more so long. This was so well explain that immediatly I was able to diagnose my problem. The 3D models where super visual tools. Thank you again!

still relevant today, worked for me.
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.

Great video just helped with filament not feeding halfway through print. feeder was skipping. The pipe needed to be pushed right upto the nozzle which stopped the blockage. awesome thanks
Thank you, that helped alot, now have a good understanding of how and where the blockages occur.
The nylon stretch method worked a charm for me. Thanks!

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!
You are the light. Thanks man.
Most useful video about nozzle clogs I've seen. Thank you!
so amazingly thorough and easy to understand
This was amazing. the crossections really helped with the information thanks
Thanks! This helped me take care of my first clog. I didn't even get one thing printed before I had a clog, so I was frustrated. It's all going and I'm a lot happier now! I hadn't seen the concept of pulling the tube out and cleaning from the top which is what ultimately cleared it!
At last, a simple straightforward video explaining extruder problems. Big thanks
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!
This explains a problem I had with my printer perfectly! Great explanations
Just what i need a week ago!
A great explanation.
Keep up the fantastic work. 😊
Great video! Clear and concise. By far the best video on clogs I've found. Thanks for giving me the knowledge and confidence to attack my first clog.
2 days into my 3D printing career, I got a clogged nozzle. This video helped me understand the why and how to fix it. Thank you for helping out us newbies.
lol, old message, but i got all this fun stuff in the first few hours on a used machine. Tons of fun learning how to fix and re build everything
Amazing explanation! Im at my wits end and you just answered every question I had!!! Thank you!!
you damn legend, perfectly explained even after 3 years. thank you.
Excellent idea to do this for the new comers to 3D printing...but ultimately you made it so much educational that even "senior" 3D printer can enjoy it ! Congrats !!
Best video I have found on the topic. Helped a lot. Thanks!
very didactic video. please more like this one !!!
What a great video. Explanation is one of the best I have seen on the subject.
The best and very clear explanation!
This vid was super helpful and I was able to clear the clog in my system as a result. Thanks! You've earned a sub.
Love the 3d printed visual aids too, cool stuff.
Thank you very much :)
These recommendations are gold for stock Ender 3 Pro parts.
Awesome video! Love the 3d printed hot end examples! Gonna fix my hot end right now!!
This!!! I needed this!!! Three hot ends later, you've come to rescue me!!! Thank you!!!
Great explanation!
Dude thank you so much for this, I thought there was an issue with my hotend but after going to town with the needle the filament started to flow freely again! Bless!
Very good demonstration!
Cleared out my first clog using a video from Creality, but this video really helped me understand everything that's going on. The visuals were fantastic for helping make this digestible and fun to learn about :)
For creality spider all metal, I use a small drill bit and drill through the jam.
Thank you very much, this kind of dedication is commendable.
thank you! I bought a 3d printer used a while back and just got filament for it and I definitely have a jam. hopefully with this new knowledge I'll be able to finally to do a test print
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.
Thanks, this video was very helpful. I'm printing since a few years but never had such a massive jam like today. Normally a cold pull does the trick - but not today. The trick with the push stick (which I had from my retired Geeetech printer) did it. Didn't even need the the heat gun :)
Great explanation, also great examples thanks!
