Subject: Re: [Homebrew_PCBs] Re: PCB-CNC Design - what files to feed the unit with for drilling

From: Stefan Trethan <stefan_trethan@...>

I just wondered which files i would have to generate for cnc drilling?
i mean for milling g-code seems to be standard (where i don't know if you
have to generate normal positive g-code
or dome "negative" isolation tracks).
but what's the standard for drilling, some standard seems to be excellon,
would you agree?
is there software which accepts excellon files?
