    X offset question.

    I am using Marlin 2.0 and I have looked and looked all over the Internet and the only thing that made sense to me was how Smoothie solves my issue but what I have a 330x330mm bed and my X Max endstop is 3mm too far over. How do I tell the ABL/Marlin/Etc... that I need the nozzle to move to 327 and go no farther over and it may fly to the left by 330mm?

    // The size of the print bed
    #define X_BED_SIZE 330
    #define Y_BED_SIZE 330
    // Travel limits (mm) after homing, corresponding to endstop positions.
    #define X_MIN_POS -3
    #define Y_MIN_POS 0
    #define Z_MIN_POS 0
    #define X_MAX_POS 327 //X_BED_SIZE
    #define Y_MAX_POS Y_BED_SIZE
    Doesn't do what I need because the nozzle is sitting there at 330 but shows 327 and to reach the end of the bed is -3 not 0. How can I get it to be 0-330 as having to always remember to add 3 to get where I am really at seems crazy.

    Something that should be so simple eludes me or Marlin is doing it wrong, or not at all. After stumbling onto the Smoothie site and reading how they did/do it I have to say theirs makes sense.
