    The question marks are normal.

    You bought it all from the site? There are a few other questions in the sticky that really help out as well.

    Lets see some pictures of you board wired up.

    Can you move the steppers from the screen?

    Your power wires are in the wrong spot. Move them over to the other pair.

    push the button (knob in), a menu pops up, select prepare, push the button, select move axis, push the button.
    no movement at all

    If you’re going to use a 3d print head on the cnc, you’ll need those jumpers. Doesn’t really matter which pair is connected to the power adapter.

    Double check your connections. If that doesn’t do it lets see some pictures of your wires and connections.

    I have disconnected the motors from the double wire harness . I have installed just one motor to the ramps board and it still did it . I then installed the opposite end motor and still does same thing . I have moved the drivers around , but the problem stays on the x axis

    24V will most likely fry the voltage regulator on the arduino

    Yes will cause damage, you have to modify the shield first and use a second power supply. Lots of info on this out here, this used to be a common thing.
