Hi Andy, I ran this code and it worked properly. The only changes I made were to add G21 and G0 to the beginning, and M2 to the end. http://timeguy.com/cradek-files/emc/andy-success.png The preview and machine motion matched. If you are getting a different result, we need more information to reproduce it. Some things that I wonder are: Does the preview look wrong? Does the machine motion match the preview? What exactly do you mean that the arcs are skipped? What else is above in the program that might influence the path? Maybe tool radius or length compensation? G64 setting? If tool radius or length comp, what is in the tool table? Can you narrow down the problem to a very short program that reproduces it, so you can post the entire program here?
