@t3p3tony Thank you for helping debug this.

It is working now, the issue was with the end-stop extender wire.

Apologies for the inconvenience.

The challenge is not resolved even when connecting to other IO ports.

M98 P"0:/sys/config.g" commands shows below response.

@t3p3tony This is what I did as the first hardware debug, Swap the X-axis and U-axis end-stop, and X homed but U has a similar response.

@t3p3tony

I think the challenge is here, it senses the end-stop is always at Home.

I have tried connecting the end-stop to other IO pins but the results were similar.

Hi

I am trying to run a U-axis Cartisian configuration. It was working fine when I was using Sensorless homing but when I changed the homing with a 5V inductive end-stop it stopped working. The U-Axis does not move for homing.
I am using a similar 5V inductive end-stop switch for the X Y and Z-axis and they work fine with them.

Please advise on what I am doing wrong in the config.

@dc42 Thank you, I will try this.

@neo0204 Confirmed it from igus documents, it's PNP.

Please help me on how to connect this.

@dc42 Thank you for your response.

I have got this, Is it PNP or NPN?

If it is PNP, how do I connect it to the duet board.

@jay_s_uk I tried this yesterday and sadly it's not working.

What else I can do to make it work?

@jay_s_uk Yes the PSU is the same,

Like this?

M574 X1 S1 P"!^io0.in" 

@jay_s_uk Also when the sensor is triggered, I checked with the multimeter, and it's passing the 24V signal to the board.

Am I am missing something in the config file or at the firmware level?

@jay_s_uk Yes, i am testing it in both states.
But it's giving the same results on M119.

@jay_s_uk
Thank you, Now the sensor detects power, and when manually triggered the LED on the sensor goes ON.

Sensor Vcc and GND are connected to PSU 24V and GND respectively.
Sensor Signal is connected to pin io0.in

But When trying M119 command from DWC it says

Endstops - X: not stopped, Y: not stopped, Z: not stopped,

Also, I tried changing the end-stops pin to,

; Endstops

M574 Y1 S1 P"!io1.in"                  
M574 Z1 S1 P"!io2.in" 

The M119 command returns below response,

Endstops - X: is at min, Y: is at min Z: is at min,

@jay_s_uk Thank you for your response.

Just to confirm, The Vcc and GND wire of the end-stop should be connected to PSU and only the signal will be connected to input/output.

Also would you please help on which pin (input/output) to use for 24V NPN Normally open end stop.

Apologies if my queries are too basic.

Hi,

I have got a new Duet3 6MB and I am very new to this field.

I have got the iGus gantry which I am able to move around and have set up the senserless homing.

Now I would like to install the igus 24V inductive sensors NPN NO.

I got the 24V endstop because the duet documents say that Duet3 6MB can handle end stop up to 30V.

But they seem to not work, there is no LED when connected the Vcc wire to 3.3V or 5V.

Please help here.

PS: I have tried the general microswitch endstops and they are working fine.
