You need to install PronterFace. And using its target in the upper left hand corner... Can you move the X and the Y axis in the correct directions? I presume this will work OK.
After you verify that... Can you move the Z-Axis with Pronterface? When you tell it to go up... Does it go up? Same question for down. When you tell it to go down, does it go down?
If both up and down move but they move in the wrong direction, you need to invert the Z-direction...
