I am so glad you made this video. My filament was knotted on the reel and it broke below the gears in my Prusa MK3S. I tried pushing with the filament with no success. I tried a #50 drill, but it is .03mm too large. A #51 drill would likely work, but I don't have one. I was afraid I was going to have to disassemble the extruder assembly. Using one of the small Allen wrenches worked a treat. It was a little difficult at first, but then moved easily. I am now back in business! Thank you so much!
Thanks for the video. I recently had my first stuck filament and ended up using the supplied needle nose plyers to work it up and out. After getting the filament out I recut it at 45 degrees passed the stripped filament area and then reloaded it. There was a nice blob that extruded before it went back to being smooth, obviously my problem. Did a test print and good to go again. The other videos I watched had the basic "heat, unload, reload" which didn't work. 3 years later and your video is still saving people from a headache, much appreciated. PS. I really enjoyed your initial comment basically saying, "It doesn't matter how we got here, but we are here." Made me laugh out loud because it is so true.
@@LA3DPrinterRepair I don’t know if you remember what to do but my spring fell out well fixing it and don’t remember where that goes can you please help me know where it goes
This was the most helpful video for the problem I was having. As it wound up the filament had broken and bent sideways. I couldn't heat it and pull the filament out. When I opened up the feeder, I saw the problem cleared it and now everything is working perfectly. Thank You!
Thank you, I thought I had lost a print entirely during a planned filament swap but the hex key trick was able to finally push that stubborn stuck filament back out the other end. I was so worried because I thought the revo hot end couldn't have this happen and I would hate to disassemble my hot end again...
Helped me as well, my roll ran out while I was asleep and it would not load the new one, the keys were turning the filament sensor off and using the 1.5mm wrench to push down. Thank you for being so calm, saved me!!!!
My printer ran out of filament during a print and jammed my extruder. This video solved the problem in a few minutes, I am very appreciative of you taking the time to share.
Just wanted to personally write and thank you for making this video. This has frustrated me for more than two months and this morning I decided I just need to google this issue, and viola! I wish I had done this two months ago!
Thanks for this tip. I saved me from dismantling the extruder. I had to bend the hex key slightly to get it around the extruder drive gear and into the PTFE tube.
Saved me after a 15hr print, needed 100grams more to go when the spool ran out. Tried to feed the new one in and i was on this exact scenario! Thank you, its back up and finishing 😅
Worked for me too.. was not looking forward to stripping down the hot end. Thank you! (on a side note I am considering printing and installing the pitstop extruder.... in case I do need to pull things apart again.)
My filament was so stuck that even pushing it with a metallic tool was not helping. I finally managed to unclog it by heating my 1.5mm allen key enough so it can enter inside the clogged filament and push it. Hope it can help some folks.
Thanks so much Lee...this was my exact problem! I did need to force down from the top..found a big thick paper clip did the trick! Thank you for posting this!
Great video. Thanks for that. I Just like to mention a thing I discovered when unloading the filament. If you do an unload filament the filament comes out and a beep sound is created with a message on the screen "pull out filament immediately". First it took me some time before I realized and read the message, but pulling it out was just going fine. Later on, when I knew the message was going to come to pull out immediately I already put my fingers around the filament to be ready to pull as soon as the sound beep would appear. My advice is not to do that. Because if you pull too fast the filament is getting stuck, It happened to me when i was new with the Prusa around 5 times. I took the message Immediately too serious. When I realized I had to wait 2 or 3 seconds before pulling after the beep, I never experienced a stuck filament during unload ever again. This can prevent you from needing to dismount the printer and repair it.
It says "immediately" for a reason: if you let the filament cool in an odd orientation, it can cool "hooked" and catch on the inside lip of the "lid". So no, don't let it sit there, but don't RIP it out like a wild-hair either, just guide it out at the same pace it's feeding and don't be a slacker about it. Maintain grip when you start the unload process, the beep signals the physical handoff to the operator (you), so pull it away.
Unfortunately had a 16 hour print fail twice at around the same time (hour 11ish) with this problem.. Thank you so much for saving me a massive headache! Mine turned out to be this combined with a clog, assumingly due to previously printing with PETG and not all of it got out. I preheated my hotend to well past PETG temps, and manually pushed out my stuck filament like in this video, and then pushed a bunch of PLA through the extruder to force out any leftover buildup inside. Hopefully clearing out my nozzle of any leftover other materials will let me fix this print. Thanks again!
If you did a tear down, be absolutely sure the PTFE in the hotend is secured with the collar, it should have no movement up and down, otherwise you can have strange extrusion issues during retraction. Good work!
Thank you so much for this video! I looked at several other articles and videos before finding this one. None of them mentioned this issue, so of course it was what was wrong with mine. haha. Thanks to you, I'm up and running again!
Thanks! I really need to do a video on general hotend “theory of operation” since it’s a universal subject and one that should have thorough understanding by all operators, not just Prusa operators!
Thanks for the solution. In my case, the stepper motor does not revolve when I insert the filament. However, without filament, it is working well. I increased the reference voltage of the stepper driver and changed the motor and it is the same.
"Could be an accident, could be filament broke, could be a tangle in the spool, could be the fact Mike N is a fool!" Well put Lee! :p Thanks for the great vid! I was about to take the entire thing apart! :D
How would you fix the filament retracting before a print? I load to nozzle, select file from sd, hit print, bed heats, head goes to board, then retracts filament back to top. Firmware is updated to latest and calibrated the xyz. first layer calibration prints nicely.
at first blush it sounds like some questionable gcode if you can run a first layer properly, make sure your profile is configured correctly in PrusaSlicer, and don't use other people's gcode.
Great video.... my question is What do you do when you hear a clicking noise. What should a check. Driving crazy. I did all this. Still the same the noise. And Can’t finish my print
The clicking noise comes from the motor, but the obstruction causing the back pressure which makes the motor stall is in the hotend, most likely if the printer has been working well for countless hours, is carbon deposits built-up in the nozzle, poke it until it flows, then cold pull it until it’s clean, or swap it and be sure to hot-tighten and do it right. 💪🏻🖨☝🏻
Thanks brother! I was freaking out because I had my printer upgraded to mk3s and the auto filament has been a headache for me. So I just turn it off and whenever the printer runs out I just manually put it in like I did with the original mk3. What do you think about the auto fill?
Hi Nikita, check my PTFE swap vid, that’s heat creep; and never ever shut the printer off hot or remove the left fan when servicing the hotend; tune into the show and I’ll touch on this; hotend fundamentals are slated for a future show! Tell us what you need to hear and we’ll chew your ear off! Keep on printing!!
Sounds like you're gonna need to swap the PTFE, I've got a video on that procedure as well; if you can't manage you can send it out and we'll be happy to assist.
@@LA3DPrinterRepair I disassembled the extruder and the hot end was not receiving the filament because the canal too it was backed up. Everything is in working order now and printing phenomenally.
Thank you for the helpful video. I have tried your steps and still am having trouble as the filament looks to be hardened right below the gears. No luck pushing it downwards and no chance of pulling upwards. I have pushed a small acupuncture needle up from below but is a bit short to get to my trouble. I have a picture of the trouble but am not seeing a mechanism to attaching here.
I had the same problem, take a sewing needle or any other narrow sharp object from the open side door and stab the bottom of the glob. Lift it up while you press "unload filament" and it will pop right out
I have the same problem. I can insert a needle from bottom with no blockage. The filament is broken right at bottom of the gear box. I heated the nozzle to 250C for ten minutes. But the filament will not budge when I insert a probe, no matter how hard I pushed. I am reluctant to apply any more force. The filament there is not melted and it feels as if it is stuck/glue at that point. What are the steps prior to pushing in the probe? What temperature are you heating the nozzle to? Are you heating anything else? Should it heat up all the way to that point of the filament? Should I take off the fan on the side, to have it heat up the whole extruder?
@@KevinKelly I had the same issue with my filament being completely clogged even with the allen wrench. I ended up heating my allen wrench with a lighter (used an oven mitt to prevent burning my hands) and once it was hot, I was able to push through from above and unclog it like the video showed. Thanks for this video and Defacto in the comments above for the recommendation of heating the allen wrench.

Didn't work for me, even tried to hit it down with a hammer. I had to go to prusa site and lookup changing the Bowden tube. The filament had expanded in the tube and clogged it. The clog was cause by not pulling the filament out fast enough while it was unloading.
