MMU2 is stucking while changing filament
Hi guys,
We have some problem with MMU2 (not S).
After using reset button it begin to working well: loading to nozzle and to extruder is OK, printing is begin, but when it should to change filament, its unload it without problem, but when its try to change a filament to another its stucks: the idler is moving to correct position, but the pulley is just not rotating. So idler rotating few more times, after that all of LEDs begin to blinking. If I reset MMU2 after that it begins to working well: the puller is rotating, it choses the correct filament till next changing and the problem begins. Sometimes MMU reseting is not helps, so I have to switch off the printer, reset MMU2 and start printing from the beginning.
I made a short video how it happens.
