I have a 2 pole NC E-stop that I want to wire into my system for safety. I am using a BOB from DIYCNC which is their PCPPS-3PS (power save) and their driver 25PS model on all three axi'. They can be viewed at
www.diycnc.co.uk. for layout and Pdf on information I am using a regulated 24V PS with 3 lead points. So what I am asking is where is the best place to wire in the E-stop.
Wiring between the Mains plug and the power supply ensures that power is shut off when I hit the switch and allows me to wire the limit switches to the board and keep them as separate controls (personally a good idea in my book). The E-stop has one 2NC switch in it and space for a second one if need be. Wiring a second one in would allow for information going back to the BOB, but if the E-stop is before the PSU why would it be needed as that seems a bit too redundant to me (still learning, if there is a reason please explain).
So, any and all help or input would be helpful diagrams would be greatly appreciated as tend to be a visual person (though if given good reference points can figure alot out).
