Need guidance on E-stop/Disconnect Switch connections

For the OP, Sray69:
Just connect the e-stop to mesa.
Just wire the drive enable properly.
No switching, no shutting power, nothing.

For the rest, stop confusing the poor guy, we are not launching nuclear missiles here.

That sounds like exactly what I have been wanting to do, but I am having trouble determining the correct way to hook them up. I thought there would be an easy solution for this but apparently there isn't. I was hoping someone could guide me through it (in laymen's terms).
 

tommylight,
Let me know what you think of this drawing. I came up with this iteration from another diagram I drew up that included a relay. I just removed the relay and rewired the E-stop.

I have 24V field power going through the NC side to a digital input. I am thinking this could work if I invert the state in HAL to "NOT". Does that sound right?
Also I fed the drivers using the 5V/GND from the unused stepgen on the Mesa. I ran the 5V through the NO side of the E-stop. 

I would appreciate any help correcting my drawing.

When i get to my PC i will check and report back.

Yes, that looks OK.

WOW! That is surprising. Maybe I am starting to understand.

Thanks for your assistance.
