Flo, If you are using CAM to generate your G-code maximize the path tolerance to reduce the number of line segments. I do 3D contouring in VisualMill and can double the size of my G-code by specifying .001 tolerance. Unless you are machining with a very rigid state of the art machine you wil never see the difference. I run with a segment tolerance of .005. Also check to make sure that you are outputting circles intead of line segments.
