I haven't quite reached the point where I need to go into the G29 command, so I haven't been reading that threat. However, can someone give me a simple outline of what G29 does, and why we want to zero in on it?

G29 is like the G28 command except on steroids. It probes multiple points on the bed and then uses that information to find the normal vector to the X & Y axis. It produces a 3 x 3 bed correction matrix that can be used by all the movement routines. When a specified coordinate (vector) in the GCode is multiplied by the correction matrix it produces a new coordinate in the new space that is properly located given the bed might not be flat.
