CNC Z EndStop

[rubens]

Hi,

I'm making a CNC with a Duet 3 Mini 5+ board and I'm using firmware version 3.5.1. and I want to use this as a endstop for the Z axis:

This is the code I am using:

; Endstops
M574 X1 P"io1.in" S1 ; configure X axis endstop
M574 Y1 P"io0.in" S1 ; configure Y axis endstop
M574 Z1 P"!io2.in" S1 ; configure Z axis endstop

and this is the connection I used for it:

It doesn't give me any errors, but the Z axis doesn't stop. I've checked the cables several times and it shows 5 volts.

What could I be doing wrong?

@rubens always connect endstops like that between iox.in and gnd. Never 3.3 or 5v

@jay_s_uk Thanks, that worked, I was going crazy.
