Limit switches were also fitted by the factory in preparation for the Proto Trak system to be fitted to my mill. The micro switch modules on the X-axis and Y-axis are wired to separate DB-9 plugs ready to be connected to the controller. I have sketched the wiring connections after continuity testing the circuit. I shall incorporate these limit switches in my drive E-Stop circuit before testing the motors.
Thanks Skullworks, I can see how easily safety can be overlooked in the enthusiasm of getting things running.
