This machine does not have many hours on it. I was wondering if the ball nuts needed adjusting. I'll re-do my gibs now and double check the numbers.

If the turns ratio was set correctly when new, and cannot be adjusted now, then it is definitely something mechanical.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.
