By default, RatOS calibrates the bed mesh before each print (it's annoying as balls). Disabling variable_calibrate_bed_mesh will stop RatOS from loading a bed mesh entirely. If you want it to load a mesh, you can set variable_bed_mesh_profile to the name of the profile you want it to load.
If variable_calibrate_bed_mesh is False, you must set variable_bed_mesh_profile variable to the profile name you wish to load, or no bed mesh will be loaded. If variable_calibrate_bed_mesh is True and this variable isn't set, RatOS will use ratos as the profile name.
The question is how do i actually save a profile so i can load it all the time and not have to wait for it to re-level before each print?
