Failed to initialise WiFi module

[CreateAndCarveCNC]

@Phaedrux I purchased back in December last year with my CNC machine from Ooznest.
Yeah, It has been working perfectly fine for all this time, with almost daily use, up until the end of last week

[Phaedrux]

Can you also send the following commands via usb terminal and report what they return?

M552 S-1
M552 S0
M588 S"*"
M552 S1
M997 S1

@CreateAndCarveCNC looks like your wifi module has died to me

[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

[CreateAndCarveCNC]

@jay_s_uk said in Failed to initialise WiFi module:

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
