    Just a thought, I've got enough shielded cable for replacing the external leads to the motors from the 4 pin plugs via the control box, how do I ground this part of the cable or is it shielded via the internal wires that connect the drivers to the 4 pin plugs as I grounded them? do I attach it to part of the cnc frame?

    with 4 pin connectors you would have to connect the earth / screen to the shell of the 4 pin chassis plug

    and then the cable screen to the shell of the 4 way inline socket
