Dennis,
Go to the Dolphin web site, SUPPORT>POST PROCESSORS
scroll down to the turning pp's and you will find the diameter and radius ones for Mach3.
Try the diameter one out.
I have attached a dxf for you to import. Define a button tool with a very small diameter, like 0.001" and use that to create code for just cutting a profile of the balls. All should work fine in Mach if Mach3 is configured correctly.
I am also attaching the code for the profile, this way you can play with the Mach settings or whatever. It does run.
BTW, I don't have anymore balls left.....
