This is from a reply I posted to the list about two weeks ago
Generating Gcode from Eagle:
Once you've designed a layout, you'll need to generate gcode from the board.
Eagle has a user expandable scripting feature called ULP. I've seen quite a
bit of discussion about a ULP script called pcb-gcode. You can find it at
the Eagle ULP download page
(
http://www.cadsoftusa.com/cgi-bin/download.pl?page=/home/cadsoft/html_public/download.htm.en&dir=eagle/userfiles/ulp).
From what I've read, the Gcode that pcb-gcode creates is not very well
optimized. There's another ULP on that same page that will supposedly
optimize the generated gcode called pcb-gcode-wizard.

Subject: [Homebrew_PCBs] Eagle layout
I need some help getting to the next level in this whole
complex PCB design. I designed a PCB using the Egale software,
the sch. and board, but I got hung up on getting it from there to
my CNC. When I coverted the board to a dxf and then to a gcode the
file was huge, and did not appear to be close to routing a actual
board. It sound like a lot of you are using print a silk screen
process, but I have a small CNC I would like to use.
So I would like to get it to the route/ drill stage,
even if it is just a test board to see how the whole process works.
Any help will help, I have read alot of info and totorials but did not
find alot of help on this.
Thanks, Mark
