    Default How to change "Home"

    Hi.
    Just wondering if anyone could tell me how I can change the home location on my router. It uses a Syntec controller, which I'm told is similar to a Fanuc . The problem is after a program runs, the spindle comes to the front left corner, X0, Y0, before shutting off. This is great if your changing tools all the time, but I'm not and just would like it to finish cutting and move to the back, say X0, Y80. This way I can unload, load without having to jog it out of the way. There must be a way, but I can't figure it.

    Thanks kindly!

    Are you sure it's not your g-code sending it there?

    1. Move the machine to the position you want.
    2. Use MDI to send G28.1
    3. At the end of your program make sure there is a line with G28

    When the program gets to the G28 line it will move to the position stored by the G28.1 command.

    Note: The above will invoke a straight line move from the previous position to the G28 position. If you need it to move up first to clear clamps or fixtures, then the G28 line at the end of the program should be something like:

    G28 Z3

    What this will do is move the Z axis first to the absolute coordinate where Z=3 and then a straight line move to the G28 position.

    The position stored by G28.1 should be persistent, meaning it should be stored permanently until changed. This should be true even if the controller is turned off, but with so many controllers out there this can't be guaranteed.

    BTW: G30 and G30.1 work the same as G28, G28.1 giving the ability to store two such positions. For example G28 could be used for a tool change position, and G30 used at program end.
