I've got Mach in the E/stop circuit because I'm thinking that if it stops running I'd like to stop the machine. Now obviously the machine should stop if Mach stops so you could say, as you have, that it's not required.
In document Mach3Mill_1.84.pfd on section 12.1 it shows the charge pump circuit being used in the E/stop. From my tests I found that when Mach is running and the big RESET button is flashing there is no output from the charge pump, when the big RESET button is pressed and it stops flashing the charge pump output is present, so I have a small N/O relay from that signal in the E/stop circuit to trip the E/stop relay should Mach stop or crash. To restart the physical RESET button would be pressed on the control panel door and this would reset both the emergency stop relay and Mach. (if the issue above was sorted out).
It may seem like belt and braces and maybe it is, I know how to fix it with extra hardware but I'd like a software fix if possible.
I will look at using brains too, thanks.Last edited by EddyCurrent; 26-11-2013 at 08:32 PM.
