When I do a two rail sweep, the cutting path 'bleeds' onto the waste area of the material. This makes for long tooling calculations, excess cutting paths and impossible clamping issues for two sided carving. My work around is to offset a smaller area for carving so the waste area is ignored. This makes 2 sided referencing a bit more complex and it still sets us passes over area I don't want to process on work that is not rectangular.
Any help on this would be greatly appreciated.
