Anyone found a decent PCB drill to G-Code converter

[mikeselectricstuff]

I've spent the last 2 hours trying to find a simple utility to take a standard Excellon drill file and convert to Gcode to drill on a CNC

So far I've yet to find anything that actually works.
Amongst the problems :
Only understands Eagle
Insists on doing all sorts of geometry correction for skewed prints and won't just do a simple conversion.
Web based tool that won't even pretend to load a file
Barfs on some fields in file
Assumes I want to isolation rout and cut an outline and refuses to just load a drill file and nothing else

Anyone?
Do I really have to write my own for such a simple task? How hard can it be?

...

I believe many of the most common CNC controller software packages like LinuxCNC and MACH3 will deal with the drill files directly without any conversion needed.

But besides that, I don't know any tool that will do the conversion, you will probably have to write your own parser and converter if the above is not an option.

Just had a look at the output from a util that almost worked and found that there is a G-code that says "drill a hole here", so shouldn't be much effort to roll my own, & make it work the way I want.
