off the top of my head..... mach setup is saying iv 4 inputs i can use... that would have been fine if i didnt have the slaved x axis
i need one for E-stop two for Z home one for Y home and one for Z home

i know there are other exotic ways of running switches parrallel/series etc but i woul like my "home" away from the extream edeges of my machine so i can easily keep an eye on lost steps

im assuming another port will give me another 9 inputs ???? cant remember,,,, my brain is melting :)
