@t3p3tony So I noticed that with the pcb mounts for the mag balls when i was close to the tower it was too close for the rod ends and they were lifting away from the mag balls. I was able to replace the carriages with ones that put the magballs at a downward angle and now my G32 returns a deviation of .015 all the way to the edge of the bed. I am still working on getting a good height map since so much changed with the carriages.
