Hello, I have a C3 index board with the optical sensor, a CD painted black with a single 5/16 or 8mm slot. When I position the slot in the sensor the index led lights. When I rotate the spindle very slowly, the index led lights. If I rotate the spindle quickly, the led does not light up. When using Mach, it shows an rpm that seems accurate, and stable. But when trying to cut a thread, it doesn't work at all. When the spindle is rotating around 200 rpm, the led won't light for many seconds, and then it will flash 2-3 times, then it's dark for a long time.
Any ideas what I should check?
Thanks,
Mike
