I'm fighting this issue, and it's time to finally get it sorted. Bed mesh is attached. I use a beacon probe with contact, and the bed is a Mandala 10mm bed.
I'm not too concerned about the max variation, but it seems that crater is not truly there. The first layer always squishes in that area. Maybe something mechanical? I don't think it's axis tilt, otherwise a full bed first layer would all be too squished right.
Another thing is even with Z-tilt, it still seems like the rear rides too high after a mesh despite z-tilt calibration with a max deviation of 0.001 set in the config.
