UM2 and IRobertI feeder - filament snaps behind bearing

Hi all,

I use IRobertI's feeder (https://www.youmagine.com/designs/alter ... ersion-two) now for many years but recently experience an annoying issue: Suddenly, sometimes after a few layers, sometimes very far in the print, the filament snaps behind the bearing in the feeder and then can't be moved anymore. This seems to happen more frequently after I change filament but that might be unrelated.

I already printed new feeder parts and replaced the bearing but nothing seems to help.

Has anybody that uses this feeder - or any other feeder - experienced a similar issue? How could I fix this?

How annoying

I didn't go that route, i did the [expensive] UM2+ extruder upgrade. That's worked very well.

I don't want to go that route for two reasons - I already have the Olsson Block and I have the second extruder populated, so I would need to replace the feeder and the feeder motor there too I guess.
