Is it running in reverse while jogging or while running code? Several ways to change this. What changed to cause this? I mean, something obviously has changed so let us know what you were doing when it changed so we can figure out the best way to fix it. Were you in ports and pins, messing with wireing, ect. ?

I am having the same issue. What is happening is one of our old machines (series 1) runs off mach3 and we just got it back from a costumer who traded it in for a new (series 2) machine. So now we are trying to get his mach machine back up and running. Everything seems to jog fine but when you PGUP z goes up but is reading negative values. When you PGDN z moves down but reads a positive value. Caused a crash and now we are very hesitant to run more programs until we have this resolved any ideas would be great. Thank you,
