i had this issue once and here's some detailed answer i got from Bambu Support:

In general, the failure to pull back the filament is due to too much resistance. It is possible that the PTFE tube of somewhere is bent too much, creating a tension that prevents the filament from being pulled back. Usually, releasing the coupler on the back of the printer and trying again can pull the filament back.

This is because this action actually pulls the filament back a bit from the tool head, so that when the tension is released, the filament could easily be pulled back.

1. You can straighten the PTFE tube first, and trying to print the following bracket model to prevent the PTFE tube connected to the tool head from being too bent:
Bambu X1 PTFE Straightener Bracket AMS Error Fix by OurAngryBadger |
Bambu Lab PTFE Bracket by Mol
Bambu Lab X1 - top glass riser by khrillian | (removing the printer's glass top cover also helps reduce tube bending)
Also ensure that the PTFE tubes of other parts are not too bent. If the PTFE tubes have been used for a long time, it is recommended to replace them with new PTFE tubes.

Thanks for this quick explanation on how to remove broken filament from inside the AMS, it's a lot easier than I thought it would be!

Great explanation of problem solving in this video, especially the not only explained but filmed details where to open what. Very helpful!

[webtemp]

Thank you so much! I had a piece of PETG inside the AMS. Without this video it would have taken me a week to read all the docs etc. Thank you !

Great tips, Kramer. I'll add one here. We were experiencing the "All 4 AMS lights flashing" issue in the middle of a print. Tried the coupler disconnect/wiggle-wiggle as well as the communication cables wiggle-wiggle which didn't solve our issue. After that, we powered the printer down using the power switch on the back of the printer near the power cable. When we powered the printer back on, we noticed the AMS lights were back to white and the printer recognized and unfinished print. We answered "yes" to continue and it picked up where it left off! We did notice a blob of plastic left behind on the actual print which we promptly plucked off to clear the path to continue. Hopefully it finishes and this tip helps others as well.

Thank you for your video! And most of all for given so many useful tips like not needing to disconnect the ams cables from the housing. It's huge and it saves people from accidents, your wiggle techniques are on point, that's from many a year of experience!

Well done video with great lighting and well articulated. Keep up the good work.

I had an issue with my AMS (the 2nd one you covered) and managed to fixed immediately. Great video and very easily explained. Thank you

[aaronlive]

Great info! Just what I needed to get my AMS up and running again.

[reebgogs]

Thank you! A couple of minutes watching this video helped me fix my AMS issue

[flrancid]

Thank you so much for this, I keep getting the first error you mention and it's been annoying the shit out of me.

[richardwmowry]

Thanks for this video. My problem wasn't identical but I found I had a short piece of filament in the feed tube and was able to push it out. I'm a new user of the X1 Carbon with the AMS and am learning the ropes.

[garrettgilbertson]

Thank you for the video and getting to the issues quickly. For me it was your second scenario and you made it easy to follow and fix.

[karlgabel]

Thanks for sharing your knowledge - my AMS error was driving me insane. I appreciate the step by step process you showed on how to check the AMS for broken filament. Sure enough, a piece broke off and was blocking things up.

[dangerverma]

Short and precise information, thanks Kramer.

[AlexandreGreenP]

Just THANK YOU for your all red lights tips!

[powell]

thank you so much, I was able to find the broken filament in my AMS thanks to your help.

[NickGurPlease]

Holy crap man. I appreciate it this video helped me out with only one watch! Great job man and thank you so much!

Solved my issue so fast with my brand-new machine! this should be on the official Bambu help page! I had broken filament in the AMS (old brittle filament my fault).

I wonder if they could design a feature where it would do something like open the tubes/path, disable the stepper motors, heat the hotend etc and you could manually push the broken filament through with another filament to be purged at the hotend? Save users from opening it all up.

[Sit-n-listen]

That's definitely what it a piece of filament under my AMS machine int the tube (thank you)!!!
