There was a patch that did something like that, but it broke the
minimum distance path optimization, so your machine will do a great
deal of jumps while drilling.
I can write a new patch, hoping that someone will ever review and
merge it; what G codes do you use for changing bits?
Regarding the milling cuts I really don't know how it could be done;
in principle it's possible to use different depths for different
layers, but how would you choose which paths to mill?
Some help will be needed from the ones that know how the png exporter works.

I'm getting by with using one bit for all vias, but it is not
ideal.
I've not used the Gcode export yet, but this sounds like something you can
postprocess.
grep or sed on the drill file should get you the separation you want...
Nope. I ran export and it gives 387 G81 lines where I get a fab drawing
with three different sizes totalling 387 holes on one of mine...
- 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.
When I export Gcodes, I get a file, tek_7k_flex.gcode.outline.cnc that seems
to be
only about the outline, I get a sequence of 389 polygons that start and stop
near eachother.
Nothing is mentioned about the cutter size, but I guess they overlap so as
to cut out the outline
along the centerline of the outline trace. (My outline was defined by a
layer called outline
holding just a 10 mil wide trace, the center of which was the desired board
edge.)
tek_7k_flex.gcode.front.cnc contained 465 polygons, so it was different...
