Oh for the drive select switches you will need to use inputs as well for each axis, I use rotary switches for this as it saves space. You can then either have a macropump or Brain look at the inputs to select the axis or you can have the inputs set as OEM Triggers and then from Config menu, System Hotkeys you can configure the triggers to whichever OEM code you like, you will find a list of OEM codes either on the wiki or in the sticky near the top of this forum.
