I am cutting a part that I have made a bunch of times with Mach3.
Using Mach4, the part cuts correctly, but the Toolpath Display in Mach4 doesn't look like what the tool is actually doing.
See the attached files for the toolpath display, and the actual profile of the turned part.
EDIT: Now that I posted the question, I see what is going on. I was viewing the bottom red line on the toolpath display as the part centerline; it is actually the top red line that is the centerline.
But, another question-I don't see how to make Mach4 "color in" the toolpath drawing as it does the motions, like Mach3 did. Is this feature there, and I just haven't found it?
