Note: The first M503 is right after an upgrade (no bed leveling of any kind performed) of the FW to v1.7.0 and notice that the mesh points are all ZERO. After an M502 all Mesh points have now been set to Z9.0000. Is this another bug or will it cause an issue for someone updating the firmware and then performing a manual level?
Since my bed sheet is already ruined I will flash the FW again and attempt a manual level to see what happens in case it is an issue.
