    Boring I.D. Diameter too large


    New here so sorry if this is in the wrong spot.

    I have a 2207 Haas SL-20A. I am having an issue boring. I am trying to machine 3.5" soft jaws and no matter what I do or how I set up the tool it is cutting to almost 4 inches. I can't tell if this is a programming issue or a machine issue or a machine issue. I seem to be able to cut O.D. just fine but when I go in with a boring bar it give me problems. I am using fusion 360 to program this with the generic haas turning post. Here is a copy of my code if that helps at all. Any help would be greatly appreciated.

    The code looks fine. Are you sure your tool is set correctly?
