Z-Axis Calibration Error?
My MK4S will sometimes think that the zero position is about halfway up to maximum. When starting a print it will attempt to clean the nozzle in mid air and fail. even if I run and pass the Z-axis calibration. It reports that the zero Z position is here, about halfway up so I can't manually move it down any further. I have to power off the printer and manually turn the Z motors past this spot and then it works OK.

It's a problem with the firmware. If you look at the release log for the last two builds it states that they've been trying (and failing) to fix it. I hope they get it right next time.
