I am looking for a post processing software, so I can speed up cutting speed, when cutting straight, and slow down when cutting corners, radius's, and arcs. I currently use enroute 5 plus, but they just told me that I have to cut the whole program at the same speed. I cut a lot of plastics, and when you cut shapes, and curves, they tend to chatter, and chip, if I can't slow down. I have a router that uses Centroid cnc software, and I have a knee mill that uses centurion 7 by milltronics. I would like to use g-code, as that is what I have been using for a lot of years. These two units use conversational programming, but can also use g-code, and you can import DXF files as well. Any ideas would be greatly appreciated. J.P.
