External E-Stop
Adding an external E-Stop you remove the current E-Stop lines from the hal file and replace them with this. Making sure you use the correct input pin for your machine and hardware. The E-Stop in Axis should stay in sync with the external E-Stop when tested. If not you may have to invert the input pin.
