MMU2 motor not synched with extruder
Hi,
after the upgrade to MK3s, I have a lot of problems with loading filament.
I noticed that when the extruder runs, the mmu2 motor, that is supposed to push the filament is not moving.
It's intended or is a firmware (3.7.2) bug?

I may be wrong, but I thought the MMU was clutched one the extruder had the filament so only one fed?
RE: MMU2 motor not synched with extruder
as soon as the extruder is loaded the MMU idler is rotated a small amount to release the filament from the drive gears. at that point the extruder is pulling and pushing the filament and the MMU is not involved at all. when the printer needs to unload/change the filament the extruder goes thru the end forming cycle and reverse feeds the filament till its out of the bondtech gears in the extruder - then the MMU reengages the idler bearing and unloads the filament past the selector
