I just purchased a pair of Emco machines for use in my home workshop, a 3rd generation F1 Mill and a Compact5 lathe with tool changer. To facilitate a more streamlined CAD/CAM process, I'd like to upgrade the rather antiquated controls to something more modern. I found one company (WelSoft) that makes preassembled upgrade kits specifically for Emco machines, but the systems look overpriced and unimpressive, so I think it's the DIY route for me.

Seeing as both machines are already equipped with CNC controls, what all do I need to upgrade? Is it recommended that I replace/upgrade the stepper motors, or can I simply buy a controller board/box and wire it in? I don't want to cut corners, but if something isn't necessary/recommended, I'd prefer to save the time and money. Basically, I just want to do this once, and do it right.

Thanks in advance.
