Z optical switch.

[Karim]

Hey guys how do I wire this switch below on a duet 2 wifi. Also do I configure and prob or switch. I want to use this as a Z probe. (Voron Tap)

@Karim best to use the probe header. You just need 5v, ground and probe.in

@jay_s_uk I got 5v +- from the panel due port. I am trying to configure it. below is my Endstop and probe.

; Endstops
M574 X2 S1 P"^xstop"                              ; Xmax endstop on hall effect board
M574 Y2 S1 P"^ystop"                              ; Ymax endstop on hall effect board
M574 Z1 S2                                        ; configure Z-probe endstop for low end on Z
 

; Z probes
M558 P5 C"^zprobe.in" H5 F300 T6000            ; set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z.74                       ; set Z probe trigger value, offset and trigger height
M557 X0:282 Y0:275 S40                        ; define mesh grid

@Karim that should be sufficient. You don't need the M574 Z1 S2 line.
Does it not work with that setup?

[Karim]

@jay_s_uk no, the switch doesn’t work , z axis doesn’t stop when triggered. That setup work when the probe was installed.

[jay_s_uk]

@Karim assuming you've followed the wiring above, i don't see why it wouldn't work.
you could try removing the ^
I have a tap kit on the way. i'll be using an assembled PCB though rather than just the bare sensor

[Karim]

@jay_s_uk I got the 24v on order too, but it will ship mid December, when I get home I will work on it.

@Karim I use a sensor similar to this one in X, Y, and Z. It's a simple 3 wire interface, and the LM393 comparator helps keep precision very high. It has an LED on board so you can tell when it's triggered without having to look at the controller.

@jay_s_uk Hey I got it working, But the Z offset is a little different.
