So yeah, you have to run it in dos box, OR... You can load it on the machine, exit into the shell and out put the dxf or whatever you want onto disk. The other option, if you have a multi format card reader, is to run it off of that. In order to play with it in the background on your cnc, a relatively updated single board computer helps. I have used it a few times with great success and wrote a "read me" file because I knew I would forget the step by step that is inherent with dos. Remind me tomorrow and I'll do my best to help you out.
