Since the discoveries in #52 it‘s not a real surprise.
I noticed that the selector on my MMU2 would not move as easily on the left side. (Most of the time I didn't notice, but especially when homing, it sometimes caused problems.) As it turned out, the steel rods were not 100% parallel. After widening one of the mounting holes, everything works fine, now. I agree the motion control needs to be improved, but maybe this helps until then. YMMV.
@fnordsh Thanks for your hint. Interestingly if I remove the motor spindle, interestingly the selector is moving a bit easier in the left part. So it is exactly the opposite as in your case.
My selector got stuck during a 2-filament print, and I couldn't find any reason for that.
I tried these without any luck:
What helped:
Now the selector is homing correctly again.
