Bambu AMS Spinning & Forgetting Filament

Does anyone know how to fix this issue I’m having with my Bambu AMS?

I have 4 AMS’s connected to my Bambu Labs X1-Carbon. Recently I’m having an issue where my Bambu Labs keeps forgetting the filament and keeps spinning. Once I think all the filament has been identified, then it forgets them and does it again. It’s a non stop cycle and I can’t print due to this issue.




I say it with an “IT crowd”-line: Hello, IT… Did you turn it off and an again? (I mean the whole Printer)

Yeah, I tried turning it off and it kept doing the same thing. So I then decided to unplug all the AMS’s and only plug in 1. It works with that but doesn’t like all of them connected anymore

Have you tried to isolate a bad cable? One bad cable could be sending bad packets.
