I use circular interpolation wherever possible.

Yeah, I've really been trying to use arcs over splines (less messy code, anyway). The thing that sucks about ACE Converter is that I can't give it two feed rates: one for -Z movements and one for X,Y movements. I either have to manually give all -Z movements slow feed rates and then give X,Y movements faster feed rates. Or, if the program is umanageably huge, I just make the whole damn thing slow, lol. Do you know of any converters that I can use? Given, I like everything else about ACE, especially since it's free.
