Converting CDR files to send to CNC software

I do not understand how to convert files so that my CNC program can use them.  I am new to cnc machining and  most of my files are in vector format and created using Corel Draw X3.  I now have X6 but have not tried to convert them from there yet.

I understand that most cnc software programs want to see files in a DFX format.  I tried saving to dxf from X3 but they are a mess when I open them in Desk CNC, my cnc software.  I know I should post this in a cnc forum and will do that next but thought I would ask if any one has any experience in doing the conversion.

Since my files are already vector it would seem as though a cad program like Auto-cad would be able to open the files I save in a dxf format correctly.  Something to do with the nodes, they are gaps between them so they are not connected.

Does any of this make sence?
