EnRoute has offered a spiral fill toolpath pattern for a long time. The limitation was that if you used this toolpath strategy on anything other than a circular shape, it could create many tool lifts that really would make it impractical to use. We have improved the design of this toolpath strategy so that the toolpaths are connected much like a hatch fill strategy so that it reduces tool lifts dramatically. The spiral fill is a much more practical strategy than in the past, providing a pleasing tooling pattern that can make it an attractive option.
