Re: Problem with Dyna 2400 CNC milling machine (ARC Problem)

That seems like a logical idea, but I actually wrote the
communications software that I am using and it always passes a <CR>
and <LF> after each statement. I have checked to see that this is
working correctly. As for the benign codes, I could put one
immediately in front of the ARC statement but not immediately after
because the controller looks for 3 special statements following an
ARC command. These three are the x locate, ylocate, and the degree
of the arc. I will give the benign command a try. Any other ideas?

Thanks,
Elliott
