So I'm making a computer board that accepts g-code, reads the scales, turns the handles, plus a few other things that I think might be fun such as a pendant, tool height and X,Y absolute position gauges.
It's okay to tell me that it's already been done and is available for 50 bucks from Geekware Inc. I won't mind

I'm sorry, but I just couldn't pass that one up. I can tell you that not only what you have planned has already been done, but done using dual encoder feedback on 6 axis with position correction on the fly! It is not 50 bucks though! I will tell you this though, I have seen a video where the developer places his hand on his mill and pushes on an axis and you can hear the steppers moving to correct the position, then when he takes his hand off, you can hear them correct again.......or I should say, you can hear them end correction!
BTW nice work!
