MMU2 load filament stops once in a few centimeters
firmware 3.7.2 and the latest for MMU2 1.05
As presented, in the attached video.
I can't figure out the reason, that happens randomly. The extruder Bondtech gear is tightened sufficiently. There is no stuck and the filament tip shapes is good enough on last unload。
thanks

RE: MMU2 load filament stops once in a few centimeters
This is normal behavior when the MMU is trying to recover from certain unexpected conditions.
What's happening is the filament isn't triggering the IR sensor on the extruder when expected, so the MMU is advancing the filament a little bit at a time until it engages. If it goes too long without the sensor showing the filament has loaded then it will error out.
