B.O.B. Limit Switches, E-Stop, Hall Sensor (Oh My!)
Ok so I have most of my controller put together, but I need some advice on connecting some things. I have a hall effect sensor for spindle speed that has a sinking output, so I need a pull up resistor on the input of my C10 B.O.B. BUT my limit switches (in series) and E-stop are NC as usual and so I need a pull down resistor for this input. Is there anyway to have these both play nicely on the same BOB? I'm thinking of putting the limit switches in parallel and have them NO but I can't have the E-stop NO. Could I cut a resistor off the C10? Everything else is working perfectly, though.
