Just for fun! CNC puzzle!

Well I was building my CNC I came across with a problem. I had already connected the end stops for each axis separately as always ON switches and then I figured out that the controller has the end stops pins connected together for each axis (the - and the + as one). So I had to figure out how to connect them without changing the wiring..
So here is the game!..
