I plotted out that snippet of code in AutoCAD and the coded arcs don't line up with the end points.
I'm not great with C but looking through Jon's code I wonder if it has something to do with how it will never output an arc with both I and J coordinates. I have no idea why Mach3 will run it, perhaps Mach has a much wider tolerance for arc-center-end-point mismatch or it is just converting the tiny arc moves to lines.
