Query about Z-probe height difference with G28 G32

MartinHMartinH
in Questions & Answers
With auto bed levelling enabled and inductive probe set as Z min end stop.

G28 requires a probe height setting of 4.45 ,nozzle just touches bed at Z0
G32 S2 requires a probe height setting of 1.45, nozzle just touches bed at Z0

Just wondering why they would be different

    That seems wrong.

    Please check eeprom value for bed coating. With inductive sensors you measure the metal distance and G28 will reduce by bed coating thickness so you start printing on surface. On the other side z probing does also consider this value.

    But homing also subtracts ENDSTOP_Z_BACK_ON_HOME so maybe you have set that to 3mm?

    Oops, learning all the time :)

    Yes, been playing about with probing and indeed ENDSTOP_Z_BACK_ON_HOME has been set to 3
