Print head moving up after MMU2S load fail  

Active Member

I have done the upgrade to the MMU2s and the MK3S however, I have noticed the following issue. Then the MMU2 fails to load the filament I press the middle button on the MMU to load which then loads the filament to the extruder. The extruder then heats up however the print starts in mid air see attached photo. It doesn't do it all the time and has done this on multiple models.

Anyone else noticed the same issues?
