Printer: Delta / Kossel Mini (slightly modified)
I just upgraded my firmware today from 1.1.0-RC6 to 1.1.9
My nozzle is 212.5 mm above heatbed and thats what the old firmware properly reported, based on MANUAL_Z_HOME_POS
The new firmware executes G28, but then reports Z=227.5 mm.
I found that Z_PROBE_OFFSET_FROM_EXTRUDER (I had set this to -15) has an effect on the Home Z Position - that seems to make no sense at all
I chose the -15 value, because I'm using an ultrasonic distance sensor (SICK UC4) and this triggers with the nozzle being 15.0 mm above heatbed.
I changed Z_PROBE_OFFSET_FROM_EXTRUDER to 0 and now the Z-Home value is correct - G28 works and even G29 leveling (I'm using AUTO_BED_LEVELING_LINEAR)
Is this situation a bug or a wrong setting in my configuration.h ?
