I've looked at the user manual and it says that by default Pin 1 of the parallel port is ESTOP OUT, in the outputs section (PC to Mill). I find this strange; isn't pushing a E-stop switch an input as opposed to an output as the manual suggests?
I also read up about something along the lines of an E-stop loop, where all the relays wired to auxiliary devices (spindle, coolant pumps etc) are in series.
Any suggestions and simple working circuit designs would be greatly appreciated. Thanks in advance!
