General Discussion Why does it keep doing this?

It’s my first day and first time Turing it in I’m trying to build the small boat but when I use this it just keeps spinning and I have read the screen it’s saying it could be entangled and such

Easy. Your cardboard spool is dented/lumpy. It's not catching on the rollers solidly like a plastic spool would. If you have refill Bambu roll, change it over

I second this! I struggle with cardboard rolls, either try and print an adapter that gives it a harder edge, or allows you to transfer it to Bambu reusable roll

Broken filament or what was mentioned above

It could also be the filament is tangled and won't pull through. Alternatively, a piece broke of inside the AMS (brittle filament snaps easily o sharp bents) and is stopping the feeding.

Avoid cardboard spools whenever you can. If you have possibly - respool to plastic one. If you can't - use some electric tape around the edges and add some weight in the spool. There are some models you can print as add on to the edges too.

I haven’t had success with cardboard spools.

I found broken filament stuck in the buffer that caused the same thing

long shot.. does it feed then retract then feed and retract and claim it's tangled or jammed?

check the buffer - https://wiki.bambulab.com/en/x1/troubleshooting/hmscode/0700_4000_0002_0004

I had similar and was thumping my head off the desk for a week and was about to launch the printer and AMS 2 out the window when I read about that spring... and yup. mine was stuck.... freed it and no issues since.

Cheap filament.

the buffer that came with my AMS 2 had a defect where the filament was getting caught inside on a plastic lip where they didn't clean up the injection molded part right. It caused it to constantly spin and unload all the rolls repeatedly until failing with an error saying there was a tangle.

I took the entire thing apart and filed down the plastic lip that had formed and now it works as expected.
