How To Clear Broken Filament Jam From A Bambu Lab AMS (It's Easy!)

I got my first jam in one of my Bamby Lab Ams units, and it's time to learn how to clear it. It was caused by broken filament and acutally very easy to fix!

You are lucky. For many this has been less than the plug-and-play item it's been touted as. The AMS needs a total upgrade. Having to literally take a machine part to fix is unacceptable especially when it is a £300 piece of plastic. I imagine a lot of people who bought it because it was supposed to be reliable will just be put off once this happens.

The 🐐 literally less than a fixe minute fix with this video. THANK YOU

Thanks for posting this. I just got my AMS last week. After 20 hours of printing, I couldn't print anymore and got an error. I discovered that one of my filaments had broken, which is what blocked the AMS. Your video helped me clear it. Thank you!

[lcalbero]

Thanks man ! First time my AMS got stuck, followed your steps, quick and easy to fix, back to work. I wish you success and continue helping us around the world ! From Brazil, cheers !

What coincidence, I just tore apart my ams 4 days ago. To install a new main frame, my gen1 was breaking off at the roller mounts. That's a lot more involved than installing a Creality from scratch 😄
Turns out our tech skills are still very much relevant in Bambu times, right!

[araiza]

Thank you for this tutorial. This helped me a bunch. First time filament broke on me inside AMS.

[carlschulz]

Had my first filament break today. Your video quickly got me back into action.

[dashingcape]

Thank you! The tube couplers (Bowden??) are the trickiest part for me, whether clearing from the back of the AMS or from one of the slots.
I've only had 2-3 filament breakages in 500+ prints. Not bad, plus I'm using cheap filament so it's to be expected. It's a pretty easy machine to take apart and put back together!

[bryanjacobs]

I"ve enjoyed your video a lot. Today the little bend at the end of a filament roll jammed the AMS. I followed you GREAT instructions on dismantling the AMS. It took some work to get the "bend" out, but your video saved the day and 2 hours of printing with PETG.

This is how I learned not to use ancient crispy PLA from years past in my AMS . . . It will snap. You will learn to disassemble the AMS ~AND~ the extruder ! - 😂

[jodiedoman]

Just what I needed. Fast simple tutorial that got me back up and running in under 5 minutes. Thank you

[ceironfaux]

First time I got stuck filament and this video got me out of trouble right away! My own fault as trying to use old filament that I hadn't kept air or moisture free!

[mayhemsmiley]

Thanks Jim, it was even easier than watching your video :) Just having some fun your videos are great :)

What do you do when you dont fine stuck filament in the tube and the AMS is still freaking out

[bigtimeny]

I bought the X1 carbon with the AMS when it was on Kickstarter and I was backer number 2812 so I've had this printer for quite some time. I have well over 2, 000 hours on the printer and for the last two months I haven't used it. I went to fire it up a few days ago had a small hiccup but fixed it and printed off ABS actually for the first time and it came out perfectly. For the next part of the project I had to print with this clear PLA that was kind of old and brittle and not really stored correctly so I put it in my filament heater for a while. I also used the ironing mode which made the windows for my project come out really nice. The issue I had was a couple days later, I forgot to remove that clear PLA so when I turned the printer on and it did its normal AMS cycle, the filament became brittle again and cracked off throughout the whole PTFE tube all the way from the AMS unit itself all the way to the top of the tool head. It kept giving me some type of error and kept trying to rewind the spool and I had no idea what was going on for a minute. What I had to do was basically what the video showed and take out the filament from the AMS end, then I had to run some filament through the rest of the tube to the tool head to clear out all the broken pieces of PLA through that hole tube system and you can only feed the filament in One direction where it goes through the cutter if you try to do it the other way you'll get stuck at the cutter or the back part of the printer where the little box thing is with the springs. It was definitely my fault. Make sure you check your PLA and make sure it's not brittle before you turn on your printer and it starts to cycle through each filament slot so nothing gets stuck anywhere in the whole PTFE tube system. Hope that helps someone. Other than that this printer has been a dream and has still left all my other printers that I still own in the dust and I haven't even used them in several months. Ivoned several expensive name brand type of the line 3D printers and I can't say enough about bambu. It beats every other printer I've had hands down. I still own a very heavily modified CR10 version 1 with custom firmware, I have a CR10 smart Pro and I have a CR5 Pro high temperature version and closed printer. I think I voned almost every single printer creality has came out with and 80% of the time they would have to be returned either straight out of the box or after about 30 days for one issue or another. Same with the other brands of printers I've owned. I was either going to buy the Bambu or build a Voron. I'm glad I went with Bambu. The only time I've ever had an issue with the printer was something minor and I contacted customer support through a ticket, they replied within 12 hours and 48 hours after that I had a new cable at my doorstep but the problem had worked itself out so I didn't have to install it. Now the last few times I've tried to use the printer I still get an error for force sensor 3 which was the original problem before so I just tap on the bed and the loose connection just seems to fix itself. I went several months after getting the new part and not putting it in and the error went away until I stopped using the printer for a couple months. Not a big deal just more of an annoyance when it happens. I got a jiggle the nut under the bed and tap on the corner of the bed where that force sensor is and wiggle the wires underneath and it usually just solves the problem. The last time I did it must have knocked it back into place like I said because I didn't have any issues for months up until a few days ago and that was after that break of not using the printer anymore.

Thanks for this vid - I had some cheap PLA (now in the bin!) which had caused the "unloading spool of death" on my AMS. This viedo plus 10 mins of my time and problem solved. No more cheap PLA from now on! Subbed - thanks!

[donj]

Thanks for this! 2nd day on my P1S this happened. The wires going to the connectors are the worst part of this repair, if only they had made the wires just a few inches longer.

[fredbergeron]

Excellent video! My wife and I just cleared a piece of broken filament out of one of our AMSs using these steps. My only comment is that the teflon tube release at the rear of the AMS may take some “finesse” to clear the back of the housings as it sticks out quite a bit.

[glennfelpel]

You are such a blessing. Thank you for all the help you are providing.

[TheQBall]

Agreed unfortunately I had to do this within 48 hours of installing the AMS unit on P1S. Filament fault, not the AMS. However I didn't realise how brittle it was and it took several attempts to clear as had snapped in several different place. If your AMS is up high, I'd recommend disconnecting from the Printer itself, leaving the bowden tube and connecting cable. This is more manageable and avoids wrestling inside the AMS to seperate. However save yourself a job and print the appropriate tool set to disconnect from the the printer (rather than AMS itself!)
