Hi.
I am building my own gantry style CNC router and have come to setting up the e-stop. The manual for the Bob shows a wire from P10 through the N/C e-stop switch and back to the ground next to P15. However this does not work. I have enabled the e-stop in Mach3/ Config/Ports and Pins/Input signals with port 1 and with and without Active Low with no result. How do these outputs work? Should there be, say, 5 volts from P10 to ground? It looks such a simple problem but, as a newbie, I am stumped. Any advice welcome.
