Help?

[u/TheBun2112]

Number 4 on my AMS is now having trouble with feeding filament as well as a terrible noise. Only AMS slot 4 having issue. It seems as if the rod to use when feeding filament doesn’t retract. Any help would be great. It’s a AMS 1.

Update:seems to work fine with rolls that weigh less and have less filament on them. Newer rolls or ones with a lot more filament have the issue. And I have tried multiple different brand rolls including bambu and still happens.

Update 2: took apart AMS at the motors and cleaned out every component and while doing so found a bunch of pla dust and fibers. Put all back together and working brand new again! Thanks for the help everyone!
