Hello,
   I would like to know if any one has experience with this problem? I am using MasterCam9.1, with the MasterCam/Mach3 post processor. I am interpolating some holes, but my machine will only make the arch on and off move. I have the holes programmed for center point with a 25% arch on and off, and I have selected enter and exit point setting. In verify, and back plot, everything looks good.

Post your code and the hole positions and sizes.
