During the initial test I was still wondering what the folowing terms meant: Whether trigger occurs on an inactive to active edge of that input (S1,default.... Does it mean that I0x.in will trigger when there is a connection between 3.3v and the I0x.in or the power is applied and connection broken. With the actual configuration I was able to have an external response only when the power was cut of from Iox.in. then the message in the Dwc was stating that an external trigger was active.... this is my first Duet board and modifying an ender 3 pro to print in 4 colors one nozzle... would really like to be able to get the trigger to work for the next steep of filament detection... E-stop first! thank you for your help with the request.

My Cr touch worked fine until i decided to incorporate a trigger for an E-stop.

I actually worked a few time while doing the test with either the pause or the reset board options.
Started a new print this morning and the zprobe did not prevent contact with the bed. I removed the wires for the Io6 in to volt a 3.3... reset the machine and it started to work again. the z-probe is on Io3. in and out. Made a few tests and has soon has the wire are connected the zprobe stop working.

What can cause this type of issues. I should be able to asign external trigger without causing problem with the zprobe. Is there a sequence of how to use this or should the e-stop trigger be in another files than config.g?

; Z-Probe
M950 S0 C"io3.out" ; create servo pin 0 for BLTouch
M558 P9 C"io3.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X-45 Y-15 Z3.718 ; set Z probe trigger value, offset and trigger height (3.63+.15)=3.718
M557 X10:235 Y10:235 S30 ; define mesh grid

; Emergency stop of the duet board
M950 J1 C"io6.in" ; Create J1 external trigger on io6.in
;M581 P1 T0 S1 R0 ; Trigger Pn trigger J1 to execute T0; to reset motherboard T1 to put in pause with S1 positive to negative reading R0 for all the time R1 for printing from sd.
M581 P1 T1 S1 R0

During the latest connection with M552 S-1 command the board is now behaving like it has PI SBC board connected. Wifi command are now rejected! The only thing connected is the usb port on com5 to power the unit.

Error: M552: Network-related commands are not supported when using an attached Single Board Computer<LF>ok<LF>

Is there anything that can be done to remedy that situation..
program files have been updated ?

I was able to update the firmware on the card to the latest versionFIRMWARE_NAME: RepRapFirmware for Duet 3 Mini 5+ FIRMWARE_VERSION: 3.4.1 ELECTRONICS: Duet 3 Mini5plus WiFi FIRMWARE_DATE: 2022-06-01 21:07:06<LF>ok<LF>

The wifi is now stable and connect without issue.
still no access to the webpage.
Thank you for you help.

Is there a way to reset the network in case this could be the reason why the webpage is not loading anymore.

@thalaniel
Thank you.
I have it now... but still same issue.
could the original firmware be corrupted with my initial upload.
I have two networks registered one without a ip adress and a second with it
is there a way to erase the network and restart anew.

First time user... I am still able to connect with the yat on the card and it says the wifi is working.
During the reprapupload i got the message that there was conflict with the software but could still navigate in the webpage. I disconnected the duet from the usb and reconnected it.
Followed some advice on the document about reformating the sd card... I could not see any files on it anyway from the beginning.

I tried roloading the sd card with the reprap

This is what I got on the last attemp at connecting.
The server at ******** is taking too long to respond.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

What are the next step in trouble shouting?
What do i need to put back on the sd card to have acces to the webpage. Is the decompressed files complete from the setup enough to reinitiate the webpage connection.

Thank you for your help.
