V2XT w/FMDC. New EMI motion cards (all 3) installed a year ago. The paperwork has the adjustment numbers like "Adjust the balance pot for 800 at rest". Problem is.... I dont know what the hell that means. Is this something I can do on screen or is there some kind of external monitoring something? Runs fine but seems to be out about .015". Screws are in great shape but I suspect the motion needs adjustment. Our local Bridgeport guy is an idiot and it seems to be $400.00 a visit so I have been hesitant to call.
