I put mdf3790 into a search engine and it took me here http://grunblau.com/MDF3790.html . Looks like a moving gantry machine with a single central leadscrew. It seems that the drawings are supplied in pdf format.I don't believe I know of any CAM system that will generate a toolpath from a pdf and given the anatomy of the machine I don't think I would be bothering anyway.Particularly if I already had a working CNC machine.
