Hi, Using the beckdac / Marlin code, if I do an AutoHome and then move the Z axis to zero the nozzle is 4.1mm above the glass. If I then do an ABL and move the Z axis to zero the nozzle is exactly where it should be.

I am assuming (probably a mistake) that the configuration.h value Z_PROBE_OFFSET_FROM_EXTRUDER is used for both ABL and AutoHome? Is there another value that would affect AutoHome but not ABL that could cause this discrepancy?
