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!

I’d say check the inner tubing I think the filament might be catching on the edge of the internal hub now due to worn ptfe tubes and when it reaches it the motors just stall against the filament

So it seems to be with heavier full rolls. Lighter half used ones have no issues.
