Hey guys,
I'm not clear exactly what it is you're looking for, but it so happens that I just added a DXF import option to a CNC editor I've been working on. It reads 2D DXF files and allows you to set cutting conditions seperately by layer. I'm getting close to a beta release, maybe somebody here on the Zone would be interested in beta testing? Anyway, here's a link if you want to know more:

If you are interested in trying it out, even in it's current state, I can make a download available. Post a reply here and let me know if are.
Regards,
Scott
