Robo E3 Pro: Grinding Noise when Calibrating, Homing, or Setting the Z-Axis Offset

If you are getting a grinding noise while calibrating, homing, or setting the z-axis offset, it may be because your bed-levelling servo assembly is not functioning. If the grinding noise is happening when the printer reaches the top and continues trying to move up, this is likely your culprit.
