G29 S0 if G29 S1 not loaded

Hi everyone,
I would like to setup my printer to run bed levelling compensation only once every power-up or reset.

What approach have you used successfully?

Thank you
David

@carlacda You can check in the Object Model if mesh compensation is being used, and move.compensation.type will equal "mesh" or "none". So check for that, and if not, run a bed mesh. You can also check for the file name of the mesh in use.

I'm not sure you can distinguish between if a mesh was loaded, or if a bed mesh probe was run, because if the bed mesh is run, it loads the generated bed mesh at the end of probing.

Object Model

Hi Ian,
many thanks for your idea. It did work perfectly.
Here below my implementation in start.g

if {move.compensation.type}=="none"
	echo {"Bed probing started"}
	G29 S0  ; Probe the bed, save height map to "heightmap.csv" and enable mesh bed compensation
	echo {"Bed probing complete"}
else
	echo {"Bed compensation already loaded. Bed probing skipped."}
