Can you comment out the M552 in config.g?

where I have to insert the comment M552? Please, can you specify more prcisely what I've to edit in config.g?
I'll post you my config.g here

By comment out, I mean 'stop that command running'. So here:

...
; Network
M552 S1 ; enable network
M586 P0 S1 ; enable HTTP
M586 P1 S0 ; disable FTP
M586 P2 S0 ; disable Telnet
...

put a ; at the beginning of the M552 line, eg:

...
; M552 S1 ; enable network
...

@droftarts
Many thanks. Ok. Is it correct? (See the code below)

After do that, how can I upload the edited config.g from the SD card to the board?

; Network
; M552 S1 ; enable network
M586 P0 S1 ; enable HTTP
M586 P1 S0 ; disable FTP
M586 P2 S0 ; disable Telnet

[droftarts]

@genioluiz7 Yes, that's correct. If you edited it on the SD card, that's all you need to do. If you edited config.g on your PC, then you need to copy it to the SD card. Then replace the SD card in the Duet and reset.

The config.g file is read by the Duet at start up. It shouldn't now try to turn on. Connect via USB and send M997 S1.

If the WiFi updates correctly, and sending M552 S1 turns it on (check with M122), then you will need to edit config.g to enable networking at start up, by removing the ; from the M552 S1 line.

@genioluiz7 I'm not sure. Try sending M552 S0 to put it in idle mode, then M997 S1.

If that doesn't work, I think whatever event caused the firmware to be deleted in the first place may have damaged the WiFi module. Looking back at the first M122 report you posted, it says:

Last software reset at 1988-01-29 20:06, reason: HardFault undefInstr, Platform spinning, available RAM 106152, slot 0

We have found "HardFault undefInstr" (undefined instructions) are quite often associated with ESD (static discharge) events.

Ian

[genioluiz7]

@droftarts So, how can I verify this?
I saw during the tests that the blu led on the wifi module sometimes flashes. Maybe is a signal that it is still alive
There is somenthing else we can try to do?

[dc42]

@genioluiz7 did you try using M997 S1 to reinstall the WiFi firmware?

[genioluiz7]

@dc42 yes I tried but nothing happened. What do you think?

[droftarts]

@genioluiz7 I've read back through the forum thread, and it does seem that the WiFi module has failed. Because the firmware on the Duet was also erased, I'd suspect either a wiring short or ESD "static electricity" shock has caused it to fail. The way that the Duet circuit is designed is that short circuits to the 3.3V rail are first absorbed by the SD card holder and WiFi module, hopefully before the main processor, so that they fail first. They are easier to replace than the main processor.

Most likely you will need to replace the WiFi module. If you can't do this yourself, there may be others local to you that can help, see https://forum.duet3d.com/topic/13875/community-repairs. Unfortunately Duet3D does not carry out these repairs itself. Otherwise, I think you will need to replace the Duet board.

Ian

[genioluiz7]

@droftarts, I've replaced the WiFi module. Now what have I to do?
I post a picture of the LEDs that are on now.

[jay_s_uk]

@genioluiz7 flash it using M997 S1

[genioluiz7]

@jay_s_uk as you can see the 'diag' light is on, between the SD card and USB.

So I follow the next instruction you send me previous in this conversation:
On Duet 2, in normal operation:

• the DIAG LED will turn on as power is applied, then turn off as soon as the firmware starts loading, usually less than 0.5 second.
• In normal operation, it will turn back on if the probe type is set to M558 P1 in config.g. Removing the SD card and resetting should switch it off. Apart from this case, the DIAG LED should normally be off.
• Errors in config.g may cause the Duet to get stuck in a boot loop, which will cause the DIAG LED to be on permanently. Remove SD card and reset.
• If the reset button is stuck in (rare), or has been mounted so it is pushed in by an enclosure, the Duet will get stuck in a boot loop, which will cause the DIAG LED to be on permanently. Check there is clearance around the reset button, or use some tweezers to gently pull the button out.
• If the firmware has been erased the DIAG LED will be on permanently.

Diag LED still on

I tried also to flash it with BOSSA, with the erase pin but the LED doesn't turn off.

Now when I connect via USB the YAT software doesn't detect the COM10

[Phaedrux]

Do you still have the heat sinks mounted? Perhaps they are making contact and shorting something.

Have you removed the board from the case and disconnected everything except for the USB connection?

Give the board a blast of compressed air to dislodge any debris that may be causing a short.

Does anything get hot to the touch shortly after being connected to usb power?

[genioluiz7]

@genioluiz7

• Do you still have the heat sinks mounted? Perhaps they are making contact and shorting something.

No, they are correctly mounted.

• Give the board a blast of compressed air to dislodge any debris that may be causing a short.

Ok

• Does anything get hot to the touch shortly after being connected to usb power?

No, nothing

As you can see below, I unplugged everything, and everything is clean and all the LEDs are on.

Now the COM10 is detected. So I tried the Fallback procedure #2 with BOSSA, but after clicked Write I clicked Verify and this warning message appeared.

What could I do now?

[jay_s_uk]

@genioluiz7 did the heatsinks come with the board?

[genioluiz7]

@jay_s_uk yes

[jay_s_uk]

@genioluiz7 then its a clone board and not covered by a duet warranty etc. Clone boards come with those blue heatsinks, duet boards do not.
If its none functioning then theres not much you can do

[genioluiz7]

@jay_s_uk Since I bought it from someone else, could it be that they were added later? I believe that is original.

I said yes becouse when I received the board they were already mounted. Ma non so di più.

[jay_s_uk]

@genioluiz7 i mean you could add them later.
The ultimate way to tell would be remove the heatsinks on the main MCU and see if theres any evidence of a sticker.
Having the heatsinks on the drivers and MCU do nothing anyway as the board takes the heat away
