@fcwilt In M558 doesn't work

Could you elaborate a bit on that?

@phaedrux Any simple gcode for leveling? I edit G28 gcode too.

Do you mean to level the bed, or to create the mesh for the surface?

Maybe this helps to explain

@fcwilt G32 works fine, but G29 has problem, so mesh.g

That looks pretty good. Are you still getting the error about the offset?
Have you done a test print with it active to see if it's working as expected?

@phaedrux Looks good, but what about the four points in corners? I started printing yesterday and first layer looks good. Object was in the center of bed and has diameter 150 mm.

A 5 by 5 mesh grid can give a false impression of the bed surface.

I use a 20 by 20 mesh grid.

Perhaps create a new height map using more points.
