mach3 / Mach4 gcode post processor ?

Hi, would it be possible to have a mach 3 / Mach 4 gcode post processor, I took the solidworks for maker which affordable, but If I'm not able to send gcode to an affordable machine, that's will problematic. I'm quit sure in solidworks cam there is the post processor for this, so why not for delmia shop floor machining? linux cnc and other affordable solution would be great too.
