To be clear, this is a discussion about the gcode z offset, an adjustment to nozzle height from the plate.

The gcode z offset is set with the SET_GCODE_OFFSET klipper command and you should read its documentation, at https://www.klipper3d.org/G-Codes.html#set_gcode_offset All other methods of changing the value just equate to this command. You can set it to a absolute value like SET_GCODE_OFFSET Z=0.075 or adjust it relative to its current value like SET_GCODE_OFFSET Z_ADJUST=0.030
