I can't help you with the Mastercam post. If you are stuck you could run it in Fanuc mode. Hit F5 for setup and it will give you the option of running in Bridgeport mode or Fanuc mode. The Fanuc mode is supposed to be the same as a Fanuc OT control. I haven't tried this yet. I just got one of these a couple of weeks ago and haven't got it going yet. Might be worth a try.
