this is the mill power circuit using the e-stop to kill the power to the mill and anything else pluged into the outlet.
note: your e-stop switch is rated at 10amps and has both normally open and normally closed terminals.
we will be using the normally closed terminals (nc) for this circuit. these wires are run with shielded cable and the circuit needs to be checked with an ohm meter before ever powering up anything. a mistake here like a crossed wire will destroy your breakout board and possibly more. keep low voltage wires away from high voltage wires (interference)
only use this method for a "total" current draw of less than 10 amps. this is fine for an x2 milling machine and a very small coolant pump but nothing larger. larger loads require a higher rated e-stop switch and probably a relay.
mach3 does not control the spindle with this circuit thats a different circuit requiring a relay.
your breakout board will control the spindle but lets make everything else work then go for options
