Hey folks - Ordered the MPCNC kit from the store here, everything was working well enough. Couple of test cuts went well. Now I’m having an issue that I can’t explain. Any movement on the Y-Axis of the Mini Rambo results in angry “grinding” sounds from both motors. Moving the connector from the Y-Axis to the X-Axis on the board and attempting to move works fine. Link to a video of what’s going on is below.

The face that the two Y-axis motors turn correctly while on the X-Axis connector, but not on the Y-Axis connector makes me think it’s the board. The X-Axis motors exhibit the same behavior on the Y-Axis connector. Anyone have some advice for me?
