Two wires endstop

[Neotko]

Hi,

I'm trying to understand a thing. I have NO endstops with two wires.

On the help it says
"Duet and RAMPS. If you are using simple microswitches, connect them to the two outer pins of the 3-pin endstop connector. For other types of "

What means the 'outer pins'? Should I use

• Z endstop
• 3.3V

Or
-3.3V
-Ground

I suppose that outter is referred according to the board img on thw wiki, so it would be pins 2-3 and not 1-2? The 'outer' word did confuse me sorry

"outer" means pins 1 and 3, i.e. the endstop connector pins labelled STP and GND on the underside of the board. Leave the middle pin (Iabelled 3V3) unconnected.
