It depends to some degree on what controller card you are using as well as the control software. Some have the ability to have both home and limit switches while others are limited to one or the other (or even none at all). It also depends on whether you are using mechanical or optical switches.Originally Posted by Hack
It's not a simple case of 'one size fits all' unfortunately.
Can you give us some info on your particular card/software set up and then maybe someone can come up with a circuit that would work in your case.
