    An advanced <Mpost for Surfcam

    I just wanted to show what you can do with Mpost, or Postform.
    This Post is for a simple 3 axis Fanuc 0MD system, but can easilly be modified for most 3 axis system.

    It is asking for Vise 1-4 and zero setting for left hand Vise in X, solid yaw in Y and bottom of the Yaw in Z.
    Also at the end of the program it is repositioning the selected Vise at the center of the machine door at the end.
    And all values can be changed, (Number of Vises, Values for Zero) , etc etc etc etc.
    All in Metric, that of course can be translated to the "Imperial system"

    (It is an 1000 X 500mm machine) The tools are in Swedish by the way, sorry.

    The Mpost can also be used with 4 and 5 axis, but it has its limits.

    Re: An advanced <Mpost for Surfcam

    Using your example line by line I was finally able to modify my post for Fanuc 0i to work exactly as I needed it to...

    Thank you very much for your post...
