I read what your saying as use two switches but conect them to the same input pin on the BOB like cropwell sugestead. Is that what your saying?

No I'm saying just use One switch. These switches sense a metal object for the trigger so just place trigger at each end using only one switch and one input.
Then set the limit Inputs for both ends to the same pin number. Mach doesn't care or even Know which switch tripped it just watches the designated input.

You can even Share the same Switch and one end trigger for Home function if you like by just setting Mach Home input for that axis to same pin number. Then turn off the Home SW option in General config so turns off Limits while it's homing and you don't get a limit trip. After homing Mach turns limits back on so your safe again.

Doing this means you only need 3 inputs for all axis including homing.

Edit: Doh didn't see Rob beat me to reply.
