A long time ago I used: outlines.ulp
- it creates a HPGL-file, wich you can import into most CAM/CNC-software
- make 1x "ratsnest" before (to have all polygons filled)
- DRC: set minimum width + distance to 0.3mm
- set grid to mm
- run ULP "outlines.ulp"
- choose device: HPGL
- choose width: 0.29mm
- choose layer: bottom / top
- set file-extension to *.plt
The width/distance values depend on your equipment.
For the drills/holes you can use the standard CAM-export with layers 44+45 and device set to Excellon/SM3000.
remark: all info vaild for eagle 6.x + 7.x, not tested with newer autocad eagle.
Other possibilities:
There is also the ULP "mill-outlines" with more settings, but no experience with that.
Also on
https://groups.io/g/pcbgcode you can find the project "pcb-gcode" with even more settings, but again no experience with that.
