Hi Leonardo,
Have you opened the generated drill file in a text editor?
It ought to have a drill depth variable in there for you to adjust in
the header. Also, I found recently that if you don't have something
drawn (eg a trace or rectangle of copper) on both top and bottom layers,
sometimes no drill file is output.
The .cnc files are not the drill files, IIRC the drill file is called
somename.drill.gcode.
I hope that helps - I'm glad to see someone's getting on with something
productive despite the festive season ;)
Best,
Ed
