I hate to repeat what everyone else has already said, but man, can I tell you? My afternoon today was filled with panic as I came to realize that I had a sort of jam I had never seen before, and that Bambu's documentation was utterly unhelpful for dealing with. Your video gave me the confidence to take apart my extruder, get the filament out, and put it together again, and I'm back and working! Particular props for repeatedly pointing out the bushings that needed to be in place. I definitely accidentally removed one without noticing it, and without your video going "pay attention to making sure the bushing is back" I would have been stuck dead in the water.
Thank you for watching and leaving a comment. When I first posted this video I got a bit of crap from people saying "why post this when bambu already has a video about it?" To me it was about showing a problem and solution in my own way and maybe that would help someone. When I get comments like yours It reassures me the time was worth spending making the video, so thank you :)
Glad it helped! I wasn't expecting many views with this one but I did it to help someone out there. Appreciate your support and hope you enjoy the content.
Thank you for that. Just the right amount of detail and excellent camera work. Found the tiny little piece of filament that was blocking my extruder gears and the disassembly and re-assembly were very straight forward thanks to your video.
Yup I had the same thing and noticed in other instructions to print out a stand to allow you to punch it out and Im like "but I cant print anything right now!" Lucky I found something and I was able to tap it out although I didnt record that at the time so kind of had to fake it in the video but felt it was important to try and imitate it again because I could see it being a common issue. Anyway thanks for watching and glad it helped :)
Oh god I feel like I invented the bicycle or sthg after de- and re-assembling the whole Extruder to get a stuck filament out. Thank you so much! BTW: I found a lot of filament pieces inside there, maybe I should do that more often. Thanks again, that was a very useful and nice video!
Your welcome mate! Hope it solves your problems. I was just looking at the maintenance guide and it recommends checking the extruder assembly and cleaning it every few months. Next thing I need to do is grease and tension the belts so I might do a video just covering a general maintenance list how to
Thank you, sir. Bambu is no help. My extruder was jammed before the gears in less than a month of use. I had no choice but to pull apart the gears. Went well thanks to you!
big help mate, i had filament stuck in my extruder and this was the fix. Also the official Bambu guide has a different extruder with different cables, so yours was helpfdul to ensure I was orienting evverything correctly on the reconnection.
Thanks for the comment and glad it helped. I copped some flak from others saying "why make this when bambu already has a video" but comments like yours show it was worth doing :)
@DraftID Indeed! Also, there's doesn't show the gear assembly actually coming out, and how the bearings, bushings, etc fit back together going in. I had a piece of filament stuck in mine that just made it all a bit more stressful. Took a lot more force than I was initially comfortable to pull the yellow gear out. Lol
Great video. Thank you for making it. I ran across your video while trying to do further troubleshooting as my extruder is still doing the same thing as before. Initially I had a hotend and an extruder clog but neither were anything terrible. Disassembly and fidling around with those tiny cables was a real mother but I got it taken care of. During reassembly I noticed I was missing the little "tensioining screw" that goes inside the spring. Without it the pieces and parts just flop around. I was able to print a replacement piece for it so I now have that installed. From what I can tell I have done exactly as you say in your video however, I'm still having the same problem where the filament gets to the gears and the gears just spin but never grab onto the filament. I notice you fully tighten the spring which I have also done. I'm curious, when it's all put back together how freely should the yellow gear spin if I try to do it by hand. I imagine slight resistance which is about where I am. How tight should the four screws in the back be? I may have them too tight which would be sandwhiching it too much. That's really the only two things I can come up with. I have an X1C with an AMS purchased in October 2024. I also put in a brand new .06mm hardened steel complete hotend kit today so there's no way my stuff is still clogged yet it's still doing the exact same thing. Any advice you might be able to offer up would be so appreciated. Sorry so wordy...think I'm gonna copy/paste this over to Reddit too. Thanks so much for your insight and expertise. I'm happy to now be a subscriber.
In the making of this video I actually had a very similar issue. I had replaced the complete hotend extruder assembly and I still had the filament not grabbing. I made the video anyway and it seemed to fix it the following time for whatever reason. I'm not entirely sure what fixed it though. As for the gear spinning, from memory it spins quite freely, so maybe instead of over tightening, try backing off so it doesnt have any resistance. I also feel like the filament I was using which was all quite old was giving the issue too. Newer rolls did not have problem grabbing. I hope you find a fix to yours, fb groups and reddit will be good sources. Sorry Im not the greatest help though but thank you for subscribing and watching :)
@@DraftIDthe reson that no one mentioning is the back lid of the extruder, You can’t just screw it down sins it then pinch the gears to much. You need to put thread lock on the screws, then gently screw them down until you feel the slightest resistance. Let the thread lock set and dry. Then stick a piece of filament in the top, start tightening the screws that tightens the spring while pushing and pulling the filament true, I also put a finger on the gear to lock it while pulling the filament back to make sure it can’t easily slip. When thats done mark the hight of the screw with a white marker, screw it out some more. Add some thread lock screw it back to the marked position and let it set. Then install it in the machine. I use a small amount of lubricant on the big gear, if thats correct or not I don’t know sins bambu lab shows one thing in instruction video and another thing in there wiki gear instructions! Hope this helps! I get perfect feeding every time after cleaning the gears and I still run original x1c gears with more than 1500h of print!
I got this one. Its not super powerful but is handy and gets most small jobs done. www.amazon.com.au/gp/product/B0B8FX9FMT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
P1S has the same hotend as the X1C but doesnt come with hardened gear set like the X1C so this guide is perfect for showing how to swap that out in the P1P/S so that you can print exotic materials like CF. Just make sure to also have a hardened steel nozzle too.
I am the second owner of my X1C, I bought it at 2200 hours about 4 months ago and I just checked and its at 3043 hours now lol. I doubt the gears have ever been changed, I may do that soon as preventative maintenance. It only ever prints petg and pla though
I noticed issues with mine right after trying to print PAHT-CF. If your quality is still good you can probably keep going. If you start getting extrusion issues it would be one area to check.
Thanks. The one I got was on amazon. There are a few available so just check the reviews of each. www.amazon.com.au/gp/product/B0B8FX9FMT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
@@DraftID It says on my P1S assembly to not disconnect with the power on. I forgot once and went to plug in my new nozzle and the entire thing shorted out. Proceed with caution!

stuck filament, glad I kept the last one, gonna clean and check that one after watching this

which electric screwdriver are you using? I like how compact it is and looking to 3d print one but not sure which higher torque motor to use.
Thank you for the excellent video. You helped me troubleshoot an issue.
Glad it helped out
Excellent video & narrative. THX...👍👍
Your welcome
You saved my day
Glad it helped :)
Should you use the silicon glue that comes with the extruder?
I dont remember any glue coming with my extruder kit.
how to remove the top plate bearing?
You will need to tap it out somehow

why does the "hardened steel gear" look like its made from cheap plastic?
I think it’s just the black coating they put on it.
😬you kept your printer on wile doing this??
Yeah no harm
Yeah it would be best to turn it off
@@DraftID It says on my P1S assembly to not disconnect with the power on. I forgot once and went to plug in my new nozzle and the entire thing shorted out. Proceed with caution!
@ I’ll keep that in mind thanks!
