Hello Forum,
I am not sure whether I have solved the problem, but I found there was an error in the drawing and or Gcode that, on simulation run in Mach 3 the program stopped. The line reads "Zero Radius ArcLine 2637". I have no idea what this means, and without being able to see the tool path I did not know where it was on the project, so I just ran a piece of material and it was in the letter "C" in some of the text. I tried redrawing the file's art work several times and this same error came up several times, further down the Gcode. But after I simplified the artwork, I got a ToolPath displayed in Mach 3 and the program ran without a problem.
So I guess, if you do not get a ToolPath image in Mach3 you had better not run the program until you find the error in the code. I hope that is correct.
