Mesh bed leveling

It looks like it's missing the row with the lowest X coordinate. the likely cause is that you have a Z probe with an X offset for the nozzle, so the probe can't reach that X coordinate. in which case, change your M557 command to start at a higher X coordinate and use a lower X spacing.
