I’ve been experiencing something odd. Whenever I use the control panel to raise the z axis to the middle of the print area from 0, the printer reatarts/reboots itself?
What could be causing this? I checked the Rambo, and the z axis chip appears not to be damaged.
When you use the dial for the LCD display to adjust the Z axis, you will have to turn the knob slowly. There is a safety built in, so that if it is turned too quickly, it shuts down and you have to start over.
Just turn it more slowly and it will be fine.
