Here is an example of the post produced for one z level cut around the larger pocket on the top side of the part. Not the o-ring groove, that was programmed with finish flowline and it is the only toolpath I can get to work OK. The top side is shown in the first 2 pictures on the left above. Tolerance 0.0005, filter arcs 2:1, one direction, xy arcs only.
