On a miller, I am installing separate hall-effect home (1 per axis) and mechanical limit switches (2 per axis).
I have the G540 controller and UC100 motion controller, so limited inputs are available.
In this configuration, the limit switches should never be actuated under normal conditions, so I was thinking of connecting them in one NC loop to the G540 Estop input, together with the Estop button.
I will then connect the home switches to other input(s), possibly using one input per axis.
An advantage is that if the limits are tripped, the G540 will halt the machine, without the intervention of the controlling computer. A disadvantage is that such a stop will be interpreted as an Estop by the controlling software (Mach3 in my case).
But I'm very new to this. Is there anything "wrong" with this approach?
