The best site is done by Scott Holmes.(Grab the outlines_gcode.ULP
on that page) See first link. He explains the process very well. You
draw your layout in Eagle and then run the Outlines_Gcode.ULP to get
the Gcode. Make sure you don't make you drawing upside down. When you
are drawing in Eagle you are looking down at the top of the board not
the back.
