Hi,
G-Code file that I used was sent before RDR sent his.
Here is the shape from Rhino as the file in any 3D format is too big for this forum.
I have also provided the G-Code with madCAM.
So as you can see Mach4 cannot display this and even a simple circle in G-Code on the ToolPath display in its true form.
Regards,
Mauri.
