Failed to initialise WiFi module

[CreateAndCarveCNC]

@jay_s_uk Do you think it is unsalvageable?

[jay_s_uk]

@CreateAndCarveCNC I would guess it will need the wifi module changing. It may be possible with a soldering iron. I usually do it with a hotair station

[CreateAndCarveCNC]

@jay_s_uk ok, thank you.

Would you say that would solve the problem or would I need a new one all together?

[jay_s_uk]

@CreateAndCarveCNC i would say that will probably solve the problem, or at least its a good place to start

[CreateAndCarveCNC]

@jay_s_uk ok thank you, can you suggest the best place to purchase from please?

[jay_s_uk]

@CreateAndCarveCNC which version of the Duet 2 do you have? The older ones have an ESP-12S. When I replaced them, I went for an ESP-07S so I could use an external aerial

[CreateAndCarveCNC]

@jay_s_uk The one I have is Duet2 Main W51596. It has an external aerial.

[jay_s_uk]

@CreateAndCarveCNC then you would need a ESP-WROOM-02U

ESP-WROOM-02U

Thank you, can you recommend a reliable place to purchase at all please?

[jay_s_uk]

@CreateAndCarveCNC amazon, aliexpress, ebay, RS. depends how long you want to wait to get one

[CreateAndCarveCNC]

@jay_s_uk thank you, I need it asap to be honest, I have orders building up

[jay_s_uk]

@CreateAndCarveCNC don't forget you can still run commands from USB so you can operate the machine

[CreateAndCarveCNC]

@jay_s_uk can I? I didn't know that?

[jay_s_uk]

@CreateAndCarveCNC yes. Any of the gcode commands will work, such as G28 to home, M23 to pick a file from the sd card and M24 to run the job. https://docs.duet3d.com/en/User_manual/Reference/Gcodes

[CreateAndCarveCNC]

@jay_s_uk thank you for this. This helps a lot. So I just send the commands via YAT bypassing the problem for now?

[jay_s_uk]

@CreateAndCarveCNC yes

[CreateAndCarveCNC]

@jay_s_uk thank you very much for the help, really appreciate it

[CreateAndCarveCNC]

@jay_s_uk Sorry to pester, but I have ben running a job and it now keeps cutting out with this code

Warning: VIN under-voltage event (9.2V)

[jay_s_uk]

@CreateAndCarveCNC that shows that you probably have an issue with your main power supply and that the board thinks the voltage is dropping below 9.2V (unless its an issue with the reference 3.3v supply on the board)

December last year with my CNC machine from Ooznest.

Meaning December 2024, a few months ago? If so, we can do a warranty replacement.
