@jeffouille I've updated the CNC Pendant wiki page, to include your wiring diagram (modified to show the connections for Duet 2 as well), the wiring tables from the Github page, and revised the text for clarity. Thanks for your help!

@dc42 Thank you for your answer.
So for the moment, I will wire the serial port to the IO_1 of the mainboard 6XD as it is working and move my button (in this io for the moment) toward the expansion board. It is not a problem I think.

The commands that I send to the UART are just json data.
The WLED support json API via Serial : https://kno.wled.ge/interfaces/json-api/
JSON over Serial
You can send commands to the WLED instance via Serial using the JSON API.
To request a JSON response containing the state and info objects, send {"v":true}.

for example I send such command :

; TURN ON ALL THE STRIPS M118 P5 S"{""on"":true}" ;LAUNCH HOMING ANIMATION M118 P5 S"{""ps"":1}" ; LAUNCH ALERT ANIMATION M118 P5 S"{""ps"":99}" ; PUT BRIGHTNESS TO 255 M118 P5 S"{""bri"":255}"

@dc42 Thank you for your answer.
As you suggested, I connect directly the nc output on the IO_IN and it is working very well. No need opto-iso indeed for NPN Proximity sensor

Already done by T3P3 on github. What a job !!!

Less than one minute to do the job.
Thank you !

@wilriker said in Laser Mode, Endstop Limit and Homing:

Your Z position after homing is beyond the configured max of 70

That was it !!
Thank you.

Now without the tool offset. Everything is ok.
I can move freely after homing
