gEDA-user: PCB gcode generation

[Mikey Sklar <sklarm@xxxxxxxxxxxxx>]

Thank you for adding gcode export to gEDA/PCB. I've been using it to  
mill boards PCBs with great results using with EMC2 and a $600  
zentoolworks CNC.

Two questions:

- Is there a way to break up the drill file so that I can switch bits?  
I'm getting by with using one bit for all vias, but it is not ideal.

- I'm struggling with cut lines. Specifically, cutting out the  
mounting holes and the circuit board edges. It would great if there  
was a way to select specific traces or vias for different mill-depths.  
Even better if I could control the order in which the cuts are made so  
I don't have a circuit board that has been cut free from it's clamping  
before the mount holes were cut. I've been creating multiple pcb files  
with the objects that I need different mill-depths. This kind of  
works, but quickly turns into a nightmare when changes are made to the  
original circuit.

Does anyone have more elegant solutions? I'm happy to use a 3rd party  
program like gcam or even inkscape if necessary.
