If you don't want to shell out for a new post processor and you aren't so deeply immersed in an existing CAD/CAM system and control software then might I suggest you take a look at LinuxCNC?I believe Fusion has a post processor that will work with it and I know that Freecad does because thats what I use.I have to admit that I have seen Vectric software and it definitely goes it's own way with terminology and general approach.It does work and it isn't hugely expensive,but either Fusion or Freecad will do the job at zero cost.
