9 months later, but thank you. I looked up someone else's video, and they didn't mention the screws or the wires in the back. They just said to unattach the back filament tube, then rip the thing out of there. I go by the "never force anything" rule of building, so I knew something was wrong when mine didn't instantly lift off like his did.

Thank you for doing it right. And I'll make sure to note this channels name as good info, and the other one as terrible info.

"do not over tight them, you just want them snug" is my personal moto. Thanks for another great video!

Thank you so much for the excellent tutorial! It's truly appreciated when knowledgeable individuals like you take the time to share their expertise with others.

Well, it happened to me either. The EMS was trying to unload the filament continuously, so I switched the printer off and took out the spool. Then, I disconnected the PTFE tube on the back, cut out a piece of filament about 1 meter long, and put it in the tube backward towards the EMS. Then I switched on the printer, and while the EMS was trying to unload the now empty slot, I pushed the filament piece until the EMS started to pull it by itself. And the broken piece just popped out. Then, I removed the long piece that I used to push back the broken piece and reinserted the spool. No unscrewing done.

Great video! My Notes: Never use brittle filament in the AMS! If you can break it just by bending it is too brittle and needs to be dried. I have had my AMS apart so many times I don't put the two screws in it anymore. The screws are metal and they screw into plastic so there are only so many in and outs left. Other than this issue I have great luck with my X1C and the AMS!

Thank you for this great tutorial. Loaded some old filament into AMS and apparently have a few inches it just broke apart and had everything hosed up. Even other roller slots would not print because of sensor failing to fully unwind slot 2. Appear to be up and operational once again.

Excellent Video! Thanks. Almost :( solved my problem.... One additional tidbit of information to add. When you remove the broken piece from the tube, check that there is no additional piece in the section where the 4 tubes come together in the plastic "consolidation" piece. In my case, after pulling the filament out, there was another small piece left in the section where the tube is connected that I couldn't even see it without a flashlight (black filament). I had to take it all back apart and remove the smaller piece, about 1 1/2 inches, that was in this plastic "consolidation" piece. Once I did this, everything worked. I had left the printer off while on vacation for a couple of weeks and it didn't like me when I came back.

Fixes AMS and insert cardboard spool into AMS. :) Thanks for the walk through I am sure were all going to have to deal with it.

Thanks a lot for the video !!! I really appreciate your help!!!Watched another one first which gave not the right hints, yours worked straightaway !!!!

Hopefully the next Bambu printer will have easier to connect/disconnect wires - ideally with a stronger connector that slides in and out easily for maintenance.

You saved me a significant amount of time. Thank you!

You are a life saver in my book! Thank you! 😊

[gadgetgurl]

finally happened to me. as always your videos are GOLD!

[avner]

Good explanation, it was very helpful, thanks.

The "fat" connector (close to you in the video) has a slot that prevents connecting in the wrong position. The "Flat" connector (away from you in the video) does not have such a slot. What is the correct position to insert it ? it has a blank side and a side with the copper wires. I am assuming copper side pointing outside (right in your video). I thid correct ?

[thomasburau]

Have you run across where a small tidbit of filament is stuck inside the divider(bad name) that pulls filament in from the different slots? I can't seem to get any filament through slot 1. Can't seem to get it going from either side after I've removed the ams from the box, disconnected the tubing and see nothing.

Great Video! However, I’ve followed all the steps and don’t see any broken filament 😮 its feeds the filament about 6-8 inches through then starts grinding, back feeding abit then forward with more grinding. I’m at 92% current mid print job. I’m afraid to unplug the electrical part of the AMS, to further take inspect and take apart. Don’t want it to cancel my print! help! Any suggestions would be greatly appreciated!

[mechrekt]

I think you was lucky. I did same thnig as you but I've the same problem and I did not solved it jet. Thank you for your video btw

[billkirchner]

Whoa!!! Check out that cardboard spool for your RED filament! 🙄😲

I'm puzzled by the recommended solution for removing broken filament from the AMS. Wouldn't a simpler and more straightforward method be to disconnect the PTFE tube from the back and allow the AMS to push the filament through until it falls out of the end of the tube? Additionally, using another spool of filament could help ensure the stuck filament is effectively pushed out without getting jammed again. The current suggestion to disassemble the machine seems excessively complicated for dealing with a piece of filament that could be more easily pushed through rather than pulled out. This alternative approach could save a lot of time and hassle for users. However, to my knowledge, this method isn't currently an option, which I believe is an oversight. I think Bambu Lab should consider investigating and possibly implementing this as a viable solution.
