Hi, I built a DYI CNC router and everything works great until I turn on the router. That is I can run cnc programs and they run great with the router motor not running. I turn on the router motor and the run program or just movement with jog and the movement will pause over and over again until the controller locks up and I have to disconnect the USB connection. I reset the USB connection and it works again. The wiring to the router motor is shielded but the stepper motor wiring is not. Any thoughts??
