Homebrew PCBs

I got eagle pcb and pcb-gcode working great on the Haas CNC machine at
work.  Anyway, I want to test how fine a resolution my lines can be.  Would
be nice to get a good assortment of 1-12mil widths and clearances.

Does anyone have a good pcb board for testing?  I think I'll just draw
straight lines if not.

I set .00001 mil isolation and .001 mil step, max .010mil and can get 12mil
lines with 13mil clearance no problem using some generic router bit.

Will try smaller tomorrow.  I think I can easily get 5mil lines and 5 mil
clearances.
