OK, I am having a problem with a customer occasionally   It has come up with 2D paths HS paths, 3D paths, it will on occasion create a large loop that violates the geometry.   Arcs are set to break @ quadrants   The only thing to date that has worked is linear output   I thought I remembered a post about an issue with Fanuc and parameters for how it calculates arc endpoint needing to be tightened or changed but I cannot find it
