Running a mastercam nc file through a hurco 4th axis.
How can I stop the 4th axis from 'unwinding'?
I've tried modifying the mmd but this introduces other problems.

I don't know if I can help because I don't know how Hurco works. But on my Haas, I was able to do this with various G92 A commands in mid program. I planned out the stop points for the A axis to fall exactly on A0 so that I could keep track of where it was going to be.
Haas also has quick rotary G28 which I use at the end of the program, but that is perhaps a little bit cumbersome to use in mid program.First you get good, then you get fast. Then grouchiness sets in.
