What controller software are you using on your machine to drive your motors? If your running Mach3, then use the Mach3 Post-Processor. The Vectric software comes with almost 200 different Post-Processors, so you design, create your toolpaths, and then Save your toolpaths using a Post-Processor that your control software recognizes. This could be .txt, .tap, .gcode, or .nc. If you have a Rich Auto controller then you'll probably be using one of the Post-Processors that saves as .mmg.
