Spindle won't start unless I unplug and replug the digital spindle controller. Spindle starts and runs, controller does not register the rpm, start light flashing, asking for a range selection and to push the start button, acts like it doesn't know its running. Pushing the start button again the light is on, the spindle shortly stops with a speed selection time out error displayed. The gear motor, for speed selection, when manually acuated, with spindle running, consistantly runs in one direction and intermittantly runs in both directions, but will not run automatically. Factory tech recommends replacing the digital spindle controller pcb. Tried contacting several recommended repair facilities, not getting any replies for repair of the board. Short purchasing a new board, what options do I have?

Thanks in advance,
