I found this diagram, mentioned in an old thread, that seems to be a good way to wire up limit, home and E-Stop switches.

My question, is if I can just put the E-Stop switch in series with the limit switches and free up a parallel port input? I assume so.

Also, should the home switches be in the same location as X--, Y-- and Z++ limit switches or offset from each other?

I am using Mach3, if that matters.
