Homebrew PCBs

To the smarter minds then My self .

Ok here is what I have done so far I have taken the .dfx files and 
removed all the fill that was in it and left only the lines of the 
traces saved as a new DFX file and when I print it out it looks good  
made G-code with ACE convertor. BUT it mills the while thing out and 
leaves the traces untouched it now looks like a eched board when I 
checked it out in K cam 3.All I want it to do is mill out the 
traces of the board what have I done wrong. Now remember this is my 
first time I have ever done this ,the board looks good but I do not 
know how this happened .  I would like some information on how to 
change the toolpath on makeing this PCB.
