Changes can be made in the pins.h file of the firmware. Look under the section for the motherboard number you are using (probably 33).
You might just try temporarily move Z to X, just to verify it is not the wiring. Typing M119 will tell you the status of switches (at least what the firmware thinks). You can just manually click the switches and type M119 to see the changes.
