On our gMax v1.5 XT+, the print head will not move in the Z Axis after leveling the bed, and will crash into the bed it if auto homed.
After Auto Home (G28), and after Level Bed (G29) - we get garble, "- *.,(" to be exact, for the Z Axis position (see attached image).
Any ideas what causes this? If we power off and restart, we'll get a "Good" level 1 out of every 4 try's.
