John, First thing you must do is to confirm that your Z axis moves positive for up and negative for down. Jog it to a position well above the work surface, Touch Off or Home to zero it, and then in MDI (hit F5 to get there) type in G1 Z-0.5 F1 or something similar. If the axis goes up instead of down you need to reverse it which you can do in the settings to the output pin on the parallel port.
