Another Home - Limit switch question

[EddyCurrent]

I wouldn't worry about the bob inputs just provide a 0 or 5v signal.

EddyCurrent, you mention that I have the proximity sensors wired correctly to a point! What do you mean by that?

I meant you have the correct coloured leads going to the right places i.e. brown + ,blue - ,black load

Is there a benefit to giving MACH3 a separate input for limits and emergency button, can MACH3 act differently?

Breakout board diagrams will generally show them using separate inputs, Mach3 has a dedicated E/Stop input.
If you want the machine to do something different depending upon the emergency stop button being pressed or limits being hit then use different inputs, you can make Mach3 act differently. I think it's a matter of personal choice, for me I want the machine to do the same thing if either happens and I don't want to rely on software that's why mine is like this http://www.mycncuk.com/forums/router...html#post52213
