Thanks for the inside Art, and of course thanks for all the hard work you guys do to kept us belly acher's happy

Scott, I believe a lot of the problems you are experiencing is due to the way your drawings are created and converted. When I looked at you drawing there was a lot breaks in your vectors which was at every place it paused and acted like it was in exact stop mode.
I corrected your vectors and re toolpathed using the outer vector cutting to the outside with 3/8" mill in 2 passes. There may be a small difference in size from your original as I did not go through offsetting etc.
anyway air cut this file and see if it runs better for you.
Run: CV On and all cv controls on the config off, also make sure you have "no fro on queue" checked.
