Need help with mesh bed levelling

G30 S-2
you only need that if you are calibrating your probe initially
G29 S0 is the same as G29
you load an existing mesh with G29 S1
Today I had the warning again with the z datum...
you need to run a G30 (normally part of the homing) before executing G29 S1

That's G30 S-1
@medicusdkfz I don't think you'd usually ever need G30 S-2

G30 ; Probe the bed at the current XY position. When the probe is triggered, set the Z coordinate to the probe trigger height.
G30 S-1 ; Probe the bed at the current XY position. When the probe is triggered, do not adjust the Z coordinate, just report the machine height at which the probe was triggered.
G30 S-2 ; Probe the bed at the current XY position. When the probe is triggered, adjust the Z offset of the current tool to make the current position Z=0.
G30 S-3 ; Probe the bed and set the Z probe trigger height to the height it stopped at (supported in RRF 2.03 and later)
