Is this a know issue? Working through the commissioning and when I move the Z-axis by more than 120-130mm at a time, suddenly the knob flips from decrementing to incrementing, as I am turning to the left, and then moments later it reboots...
It's a bug in Marlin, my current printer does exactly the same thing. Just have to move it in stages rather than all at once.
Man, I think my blood pressure is up 50%! That is an insanely annoying bug (especially with the reverse wheel and loud beeping!)
You may take the current ultralcd.cpp from the marlin RC3-bugfix-branch, I did and it works. https://github.com/MarlinFirmware/Marlin/pull/3050
