I work for a lighting company in FL(we also do some signage). We have a Computerized Cutters AccuCut Model 48. Its a CNC Router that is computer driven via parallel port using a program called MaxCAM. We'd like to run the machine independent of the computer so the computer is free once the files are sent to the CNC, preferably using 3d gcode. Where would be a good place to start as far as hardware and software?
