I am recently retired, but still want to use my Multicam 3000 for art work. I have been running Enroute 2.5 since I purchased the machine, unfortunately my windows 98 computer is dying and must upgrade to windows 10 system. Being retired, I can't afford the new Enroute upgrade. my question is: Can I install a cheaper 3-D milling program without having problems with the existing DNC? If so can anyone suggest a program.
