I have bought a 325 for my own hobby use, and need help setting up a computer to feed it. I am on a budget so please keep that in mind. I would like to know what type of DNC software works well with the 20 controller, and if there is an affordable CAM package out there? Will I need an older computer with Windows 95/98, or will a newer version work? I last ran a Tree 7 years ago and all of this was already set up when I got there. All I did was write programs and machine parts. That system was not very reliable at drip feeding. I basically need someone to tell me "this is what you need". I have spent hours looking at old threads trying to find the answers, and it can get confusing. Thank You in advance for any and all help and suggestions.
