Or even cheaper, use the sun instead of a uv light. Works great for photo resist silk-screening.

the correct answer is "dont bother" milling PCB tracks is a rather silly way
to make PCB's anyway. All you need is: 1 pack of 'LaserStar' paper that you
can print the PCB mask onto, a UV lightbox (cheap), 1 bottle of developer, 1
bottle of ferric chloride. With htat you can make MUCH better PCBs than you
ever will on a mill, in half the time. It's quick and neat, and just as
professional looking as the ones you get from a PCB house. Use your mill to
drill the component holes instead.
