Eric, Personally, I think the best way to cut insanely small segments is not to generate them. Instead of doing a P0.1 on the machine side change your tolerance on the CAM side. I do a lot of contouring in using VisualMill and the size of the G-code varies in direct relationship to the tolerance. I'm not doing high precision molds in a climate controlled shop so a couple of thousandths of an inch on contouring is usually fine.
