ok, I really has no idea where I should have put this post, so here it goes.... I am using Catia V5 for my cad-cam software, it has several post processors already built in that I finally figured out how to access. I have tried a fiew of them, but none seem to work well unless I do some "massaging" to them after they have been processed. I was wondering what machine the G-code that Mach 3 uses came from. I have a choice of several different machine post processors including: Acrimatic, Fanuc, Fadal, Haas, Fagor, Dynapath, Okuma and many many more. Or will I have to actually find a post processor specifically for Mach3, and install it onto Catia?
