Great, thanks Andy. Seems like an interesting project. If I end up doing
it, I'll be sure to post updates on my progress.

Hi all,
I have been pondering a possible CNC shaper project for a while now. I
have some chinese AC servos lying around and have pondered CNC on my little
Atlas 7B metal shaper. I have a production application for this, so it's
