i only use this thing in the winter, so it has been off for a while. this time when i cranked her up at least 3 or 4 of my programs come up with the zero in a different spot,,for example. i cut from the tailstock end (+ x) to the headstock (x0) in the offending programs it cuts from the headstock to the tailstock as if the direction of plus and minus are swapped. run these programs hundreds of times, no problem. load up another program right behind it,,all ok? any ideas?
