I have been trying fix my 1630 sx lathe now going on 2 weeks. It has a dorian turret on it. The screen says the right tool # the turret says the right # and the led in the black box says the same # but it keeps bring up code 85 to reset the index. The machine will just stop. I have checked every thing prototrak as asked and still no run. Now they says there is no more they can do via the phone. Any help?
