Are you using a lathe or mill?
I never got it to work to good. I think I used the E Z path code, but it kept putting big arcs in the code.
All I had to do was delete the lines containing the arcs, the G2 codes.
When I bought the license for Mach, the NFS turn wizard worked for what I was doing, and I learned a lot more about g code by using it too.
The NFS turn wizard is a lot better than the free ones.
The Mach 3 post listed for featurecam had a redirect virus in it, that I found with malware bytes. It was driving me crazy.
