Just tried experimenting with several settings.  I set #define ENDSTOP_X_BACK_ON_HOME 20 and the nozzle is now 30 mm to the right of the left edge of the print area.  I set #define ENDSTOP_X_BACK_ON_H

so it is just on the edge of the bed.  I set #define X_MIN_POS -10 and #define ENDSTOP_X_BACK_ON_HOME 10 and the nozzle is in the exact same place but the position in firmware says -10 now. When I se

you can change #define EEPROM_MODE 1 to a different number before uploading to EEPROM. It should overwrite. Also I run the clear_eeprom sketch before uploading.

If you have a inductive probe fitted, shouldn't this be 0 #define EXTRUDER_IS_Z_PROBE 1

It will go down #define Z_PROBE_HEIGHT 0.5 and then raise #define Z_PROBE_Z_OFFSET 0 (bed coating). Does not look like much but you should check the eeprom values. They may differ and explain the prob
