This is my first post here on CNC Zone and I came across your post. I'm looking for similar info as you. Not sure how your doing with Mastercam for programming. I'm in a similar situation with a Techni waterjet. Very unhappy with their software, doing manual leadin/out and nest is really bad alone with about everything else. No better luck with cut quality either. Mfg's answer is to slow it down but now we lost our competitive advantage and still can't cut a round hole. We are really struggling to making good parts. Have over 12 years experience with a different brand waterjet so this turned into a real setback to say the least.
