I am having an issue with our Partner VM17 (yes it is an oldy) the issue is with the handwheel axis move. It seems to be stuck going in positive in all axis, I have replaced the hand wheel encoder, and even went as far as pull the memory (brains) out and sent to Milltronics. (which I must add they were really speedy 1 week). They benchtested them made a few adjustments but still I have this problem. It worked good for say 1/2 hour after I hooked them back up then I turned it off and went home for the day only to come back the next and have this nagging problem. By the way the Jog function works fine, Any suggestions would be most welcome. Thanks
