[Solved] "Z'" axis calibration fail after upgrading to MMU2S
I upgraded my mk3s with the new MMU2S, everything checked, but upon doing z axis calibration, the following happens.
Z goes up all the way, LCD prompts for cleaning nozzle, z goes down to left front of heat bed, finds first heat bed calibration point, moves to mid heat bed, then crashes into heat bed when it comes down. it did this 3 times in a row.
I have uploaded and flashed newest firmware on both MMU2S and printer....
What am I doing wrong??
