I may have found the culprit, I went back to my last backup of the config and config override file and that didn't help. But afterwards I checked each tower and if it is moving as it should. After measuring the X and Y towers are both moving 100mm when asked to but when the Z is asked to move 100mm it only moves about 96mm. Has anyone seen this before? how is that possible if all are using the same belts, same spec motors and M122 is not showing any step errors or anything. I am hesitant to change anything on the Steps per mm for just 1 axis if everything else matches for them...
