    I am having difficulty setting up the homing.
    Marlin pronterface - when I hit the home button in pronterface - the x axis move towards the endstop. But instead of moving all the way it will only move 75-100 mm then stop. I hit enter again and will repeat the short movement. Does anybody have any clues as to why this is happening?

    Reverse the end stop logic in config.H

    so which ever one is giving that behavior, change
    eg:
    from this:

    // Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup).
    #define X_MIN_ENDSTOP_INVERTING false // set to true to invert the logic of the endstop.

    to this:

    // Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup).
    #define X_MIN_ENDSTOP_INVERTING true // set to true to invert the logic of the endstop.
