From how you've described it, it sounds like the value setting for steps-per-revolution or steps-per-degree might be wrong.
Are you able to jog the 4th axis 360 degrees so that reality and the controller agree what is 360 degrees?
If not, well, we'll think about something else. But that's where I'd start. If a jog of 360 or some known amount isn't right, then
check the value and call NWA for the right value. Sorry, I don't have the 4th axis and so don't know it. Usually it would be a multiple
of either 220 or 200 motor steps/rev divided by 360 degrees. So, if they're using 1/8 stepping microstepper drivers and a 220 step
motor, that would be 220 x 8 / 360 steps per degree, or 4.888888. A 200-step per revolution motor would be 4.444444. Give it as
many digits of precision as it will take. Also any reduction gearing would need to be included.
IIRC in the control panel software, you get to that part with Ctrl-G, and then the password of 787. Yeah, everyone has the same
password, and it can't be changed. It's like a boss-code everyone knows; a key to the executive washroom, if you will.
All conjecture; sounds like a frustrating thing. Stock is expensive! It's not like rolling pins just fall right out of the sky (thankfully!)
