Motors not moving on newly-build GRBL/Arduino CNC mill.
Does this channel have to be for Rat Rig machines? I figured I'd ask here since there has to be some overlap.
So I'm currently retrofitting a Roland MDX-40 with a newer board. I'm using an Arudino Mega 2560 with the CNC hat and DRV8825 drivers and GRBL-Mega-5X for the motion control.
My first issue is this: with everything hooked up and turned on, the motors have holding torque (I can't turn them by hand) but do not move at all. If I jog or issue move commands through UGS, GRBL thinks they are moving, but nothing happens.
Also, the motors do work when controlled by my 3D printer board, so the hardware is fine.
Where should I start?
