Has anyway tackled this kind of project? I have a few old inject printers, a couple with built in scanners, and a huge HP laserjet printer that I can plunder for parts. My question is, is it possible to be a PC/Laptop driven CNC router entirely from salvaged parts, without having to buy an Arduino board, or other board. Surely the existing devices have everything I need?
I've seen plenty of projects that always end up saying I have to buy something, which I'd like to avoid if possible.
I have a Dremel style tool already, so don't need to buy anything like that.
