…work in progress…

See https://www.klipper3d.org/Probe_Calibrate.html for details on probe calibration.

Note: calibrating the z probe is NOT the same as setting the gcode z offset.

Also Note: the “z offset” set as part of probe calibration is not the “gcode z offset” used to fine adjust the nozzle height for printing. The z offset referred to in probe calibration is the “z probe z offset” or the offset distance between the probe and the nozzle in the z plane. There is also an x and y probe offset.

WARNING: latter versions of the Elegoo firmware have purposefully broken the z probe calibration routine from automatically saving the z probe z offset value as part of the last “SAVE_CONFIG” step and may likely need to be manually set instead in printer.cfg.
