Use small endmill to mill holes of various sizes

[JohnAtl]

From Dave Z:
Hello. I love the pcbgcode add on but I can't use it. I have an ATC on my stepcraft 420 machine which is what I use for making boards but it only holds 5 bits and many of the parts I use have several different sized holes. What I have been doing to work around this is exporting the DXF file and importing it into VCarve. Then I use a 1/32 end mill and do a profile cut inside each hole.
I'm not much of a coder but I would think that this would be fairly easy enough to add and it would save having to have multiple drills in a rack as well as being able to cut even large holes for mounting etc.

This is good.
I think a good option is to choose one (or more than one) tool diameter to drill, and generate a helical descent of the target radius

[MARIOBASZ]

I am after the development of my own economic ATC, so it is also a solution that interests me. With hole diameter and milling data, it is feasible to make larger diameter holes than the tool. I have made a complement for helical descent in BCNC, with help I think it can be implemented directly in Pcbgcode
