Homebrew PCBs

I don't know that much (nee, anything) about the laser.  It's a Epilog Helix, which is something in the 50mW range.  The laser is focusable, but I was told that the documentation states that the minimum beam width is 8mil.

All I know in this area is second-hand and can probably easily be verified by looking at their website.  The whole machine is probably in the $10-30K range, I'm guessing.  I don't know how many flavors it comes in, so I don't know what the cheapest cost machine in their line is that you can get away with.

I also don't know what % power we've gone with because someone else usually burns the boards.  It might be possible to go down to a lower power laser in their line.
