    That was the best video explaining the hot end and clogs and jams I have ever seen on TH-cam. Respect Sir !

    • @shurmurray
      @shurmurray 4 ปีที่แล้ว +10

      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.

    • @briangunderson3859
      @briangunderson3859 3 ปีที่แล้ว +3

      Agreed! I had no idea there was so much involved in the hot-end. Amazing explanation!

    • @elvisglazier6358
      @elvisglazier6358 3 ปีที่แล้ว +3

      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.

    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.

  • @GreyGhostR1
    @GreyGhostR1 2 ปีที่แล้ว

    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!!!

  • @GreenGuyDIY
    @GreenGuyDIY 9 หลายเดือนก่อน

    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.

    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!

  • @RetroRogersLab
    @RetroRogersLab 4 ปีที่แล้ว +1

    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.

    @als1023 ปีที่แล้ว +1

    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!

  • @VictorLopez-ws4iq
    @VictorLopez-ws4iq ปีที่แล้ว

    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.

    higher temps usually fix clogs in the nozzle and clear out whatever's inside, jams in the extruders are more common and you'd need to disassemble the extruder.

  • @u9Nails
    @u9Nails ปีที่แล้ว

    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!

  • @Theguitarguy972
    @Theguitarguy972 2 ปีที่แล้ว

    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!

  • @willpolicarpio3493
    @willpolicarpio3493 4 ปีที่แล้ว

    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.

  • @calfeggs
    @calfeggs 3 ปีที่แล้ว +1

    Thank you! I was having trouble understanding how the internal path would keep getting jammed now I know that the tube has to seat all the way down on the top of the nozzle, and keeping the heat sync fan running is important.

  • @christophelauga6668

    I had a different issue with the Mk10 (Ender 3). The molten filament somehow made its way through the side of the PTFE tube inside the heat break. The leaking filament cooled down (due to contact with the heat sink) and was completely stuck in place. I could not even remove the PTFE tube from the print head. I ended up drilling through the filament from the nozzle side to release pressure, which was stretching the tube against the heat sink. Gladly there were no other issues for several months now.

    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!

    Great video. As a printing newbie, it is very welcome. You might want to think about reselling a bunch of those special tools. Thanks again.

    All metal heatbreaks I have a 1.7mm rod, take off the nozzle and pull the bowden tube. heat hotend to 180C and wait. yank filament I can from the top, then shove the rod carefully down through. clog usually comes loose and pops out. clean off rod and pull it back. run through a second time if you really feel the need to. let cool, reassemble, reheat, seat nozzle and good to go in less time than any other method I have seen. Important to get a precision 1.7mm machined rod, can find them on amazon.
