Router wiring and emergency stop

Hi,

I've read the guide and watched the video for adding an emergency stop button.

Am I correct in thinking that “the router AND it's power" have nothing to do will the supplied machine, duet board and power supply?? In other words, the router cable goes “up in the air to a hook" then back down to a 13amp mains plug socket??

Placing an emergency stop button in that scenario is easy - break the live feed, wire in stop button - job done.

Your guides “stop the actual machine and stop the program being sent" - however, the router would still be running ………, which would be dangerous.

How can I wire an emergency stop button that “does ALL three" i.e stops the router, stops the machine, stops the programs??

If this is possible, is it then possible to have, 2, 3 or 4 stop buttons - one on each side, one at the front, one on a breakout “control console" located 3 feet to the right of the machine? (I'm planning of trying to get the Duet/Power Supply/Mini PC remotely located in a large flight case, so that the “brains" can be taken home each night and not left in my workshop).

Thanks - Kev :-)
