I'm considering converting a surface grinder to CNC. To start, I'll probably just convert the longitudinal and transverse axes.
I'll go with steppers for this -- I'm thinking NEMA-42 motors. My current Bridgeport clone uses servos and Jon Elson's hardware on a little Intel Atom Box. I'm thinking of using a Rpi for this. It will need a minimal display/control panel when completed, but initially will need a display with touchscreen or mouse and possibly a keyboard. In the long run, some buttons. and perhaps an mpg might be useful. I'd like to use a raw Rpi without adding special hardware directly. That probably means using a USB or ethernet interface to control the steppers. I'm thinking of using Mesa hardware. Can someone suggest the most cost effective way to do this? (Although I have to admit, that after buying the timing belts and pulleys, the steppers, power supply, stepper drivers, ..., it's too late to be really cost effective.). And the surface grinder only cost me $300.
