…work in progress…

Like many things Klipper, you'll need to use at least Fluidd to access the Klipper console. You can also use it to edit printer.cfg if you don't use ssh or other methods.

See https://www.klipper3d.org/Probe_Calibrate.html for details on probe calibration. As the geometry of the toolhead fixes the location of the X and Y probe offsets, and they have already been provided by Elegoo in printer.cfg we only are concerned with calibrating the probe Z offset in this procedure.

The z probe calibration will need to be performed again if the plate is changed, or the nozzle, hot end or tool head are changed.

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

Also Note: the “probe 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. Make a note of the value produced by ACCEPT and note it as you may need to manual edit / enter this value. Make if using the Klipper managed values in printer.cfg they actually got stored there and if it's stored as zero remove it and manually enter it into the [PROBE] stanza in the file.
