Core One / MMU3 Issues unloading filament (works fine loading it)
Folks,
I'm having an issue with my Core One / MMU3: It seems to be stopping or getting jammed when unloading a filament (both Ultrafuse and Polymaker ASA).
What causes the MMU3 to freq out unloading... (Works fine loading...)

it happens to me (ABS) when it's standing for hours e.g. after some failure, then trying to remove the filament which got stuck in the printhead in the meantime.
My core one sometimes thinks it's out of filament at the printhead, which seems to be caused by vibrations.

Yeah, I just check the MMU3 by opening it up and looking. No crap in there that I can see and all of the functions appear to be working properly. I'd call Prusa support, but that were less than helpful last time.
