Hi, I'm starting to use X4 (came from X2) and for some reason, when I do pocketing operations and simulate the toolpath some somes appear to be left un-machined, I would appreciate some help as to why is this happening. I attach the mastercam file and jpg of the toolpath simulation. Ironically, I can't upload mastecam files directly, had to zip it. Let me know if you need more info. Thanks.
