Recieved this email from Gerber Service:


Open you spindle controller and turn everything on, it should say calling or call waiting on the display, do a motor warm up does the display change?
It should change to 100hz if you do a motor warm up from the keyboard.
Let me know if you get an error code.
But if it does not change at then yes you most likely are having an issue with the DUART card or cable that runs between the electrical box and the spindle controller box.
