Universal G-Code Sender and a diy Arduino CNC

Anybody etch pcb's using an arduino cnc? I have most the items needed except the frame, which I am building. Oh, and the spindle motor for the bits. I'm hoping the little nema17 motors are good enough to move one of those spindle motors around..
I'm sick of chemicals and also want to try this for double sided stuff.
