Has anybody tried doing this at home? I would like to, if possible, build a CNC machine that uses maybe a air brush tool to plot down photos, images, logos, or text onto a surface.

Gave it alot of thought, and I would want the machine to be able to do at least a near photo quality plot. Do you think this is possible, has it been done?

I'm good at the software side of things, and am ok at mechanical. I'm confident that I could write a program to do this.

What y'all think of the possibilities?

Peek into this site - http://www.pixation.com/. Quite interesting.

Good site, with lots of technical info. But what I'm really looking for though is home hobbyists that may have done this, on a much smaller scale. Potential uses might be to paint on machines, make small signs, or automotive painting.
