Hello all, I recently purchased a Heiz high-z router which included ConstruCAM 3D and WinPC-NC USB. I soon realized that Mastercam is much better than ConstruCAM so now I'm learning to use it. Though, after opening Mastercam .NC files in WinPC-NC, it reads the code, draws the path, but it doesn't execute it (after executing the file, it instantly "ends" and of course the machine does nothing). I have no idea why. Please if any of you has experienced a similar problem or use such CAM / control software combination, I'd be grateful to recieve any advice. Thank you very much.
