Encounteres a bug that made my printer inoperable. In some areas of my brinting volume printer wil lift print head up about 0.2mm and move down when moving back through this "border". It seems like it always does this by stopping Z tower stepper motor for a fraction of a second. Anyone encountered this? Any fix? May be there is some leveling grid or something, but it is disabled in config. Tried firmware from here and few versions from smoothieware. Steppers are 0.9degree, board on 32 microstepping, 400 steps per mm.
