Ok regards the Z axis then you need to enter a negative number, all Z moves are usually negative moves. So try something like -20. If you don't enter a value after it moves then Mach3 will default back to what was entered before.

I'm not clear on what your saying regards it not moving.? I think your saying it's NOT moving when you enter g0 Y20 X20 into the MDI.? If this is the case then make sure you are not at those coordinates already as this about the only reason I can think of why it wouldn't move.!

Best thing to do is ZERO each axis then enter G0 Y20 X20. If it doesn't move then I can't imagine why not as just setting the steps per with the calibration tool shouldn't stop it moving unless something went badly wrong. What are the numbers entered into the Steps Per for each axis.?

Regards the tiny move distance then make sure you haven't accidentally put it into Step Mode. Click the TAB key and the Jog tab will come out from the side. In there you will see JOG MODE button which will cycle between Step and continous Mode.
