Mario is grinding when it goes to home.
It was some combination of the following:
- It was left in rotary mode
- The green direction control wire on the connector at the Y driver was broken
- One of the wires on the Y limit switch was not on very good.
When I swapped/plugged in axis turned machine back on the Rotory axis was not a selectable option it was greyed out and slide to off
Possibly the USB connection between the computer and machine was down at that point.
