Firmware modification for I3Pro C

[WoletzMi]

Hello friends
I am new and therefore I would first like to say a few words to me.
My name is Michael and I am from Germany / Bavaria
I am new to the 3d pressure fever and bought myself an I3 Pro C.

So far, I'm really happy with the printer.

Now I've played the "new" firmware 1.1.8 on my GT2560 Rev A + Board.

However, I would like to work with only one extruder and use the second extruder port as the second z-axis driver.
With a 2nd Z-axis stop switch

What do I have to change everything in the firmware to operate only one extruder?
Countless entries seem to refer to the 2nd extruder.

Thank you for your help.
