@Md3Man Ideally, you set the Z datum in the centre of the bed with G30 before running mesh compensation. This should give it a Z=0 reference point to work from. However, if you do a mesh compensation without setting Z=0 before, and run G30 after, the mesh map should be raised or lowered (as necessary) to this point.

@Md3Man Sorry, yes, should have said that you need to add M915 to your config.g!
