Ok, there are two different things here, FeedHold and E-Stop.
FeedHold will stop your machine in a controlled manner and you will not lose position.
E-Stop is for emergency use, it will stop immediately but you will lose position.
You could have either or both from external buttons but I would say a properly configured E-Stop is a must on any machine.
The way most Breakout Boards, I have seen, work is you can have an E-Stop button connected and when that contact is broken the BOB will stop putting out pulses and at the same time will inform Mach of the E-Stop condition, which will put Mach into Reset.
I have no experience with your BOB so I am not sure if this is the case with it, I will try and have a look later in the day.
