From the developer:
CAD To DMC software translates AutoCAD or equivalent .DXF files into Galil language commands (.DMC). The CAD-to-DMC software package generates a Galil motion program from a 2-dimensional CAD drawing. This allows you to draw complex motion paths and avoid the time consuming task of programming a list of coordinates.
The software reads in a standard DXF file and converts it into the proper Galil Digital Motion Controller (DMC) commands.
