Greetings, the extensions .bot(bottom) and .cmp(component) are eagle
extensions, you also need to generate the drill files for the board,
which is in the eagle control panel under CAM jobs, excellon.cam,
this will generate a drill file that contains the drill sizes, and
x,y coordinates. I'm not sure if a cnc machine can read the drl file
because I don't have one :( You may need to convert it to another
format like gcode I think.
