Although the program I use can convert splines, I would rather not use them because it plots too many of the points and the CNC actually has trouble catching up, lol. Is the design you made with arcs or is it splines?
No problem with CNC mill catchin' up...all you have to do is just use circular interpolation. However, you have to take care to define the geometry right...sometimes you have to use parts of a circle (arcs and NOT ellipses or splines) to get circular interpolation right later during G-code post-processing.

I use circular interpolation wherever possible.
