Duet not connect in anyways - Clue: nozzle fan always on

genioluiz7

@droftarts I'll try too. Thanks

jay_s_uk

@genioluiz7 it doesn't look like you've killed anything and it also doesn't look like the firmware has been erased.
I suggest unplugging everything and seeing if you can get it back to life

@genioluiz7 The 'diag' light is on, between the SD card and USB. In https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond it says:

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.

You haven't shared your config.g, so I don't know what probe type you're using, but most likely the firmware has been erased.

@droftarts I checked the SDcard and seems like every thing is there.

@genioluiz7 That's not where the firmware is that the board actually runs. The firmware needs to be flashed to the board itself. If it has been erased (and it looks like it has), you will need to flash it with BOSSA, see https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#all-other-duet-boards

Looking at the date of your firmware on the SD card (30/07/2023), you were running RRF 3.4.6. Use the "Duet2CombinedFirmware.bin" from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.6

@droftarts ok, I tried and finally now I can homing the axis. But the board still not connect to wifi connection.

@genioluiz7 From M122, the WiFi has not started up:

 = WiFi =
Interface state: starting2
Module is disabled
Failed messages: pending 0, notready 0, noresp 0
Socket states: 0 0 0 0 0 0 0 0
ok

Send M552 S1 and see if it reports any status change.

If not, you'll need to reflash the WiFi firmware. Fortunately, this is easy. First, make sure you have the 'DuetWiFiServer.bin' file on the SD card. It will be either in the /firmware folder, or in the /sys folder. You can check this on the Duet by sending M20 P"/firmware" and M20 P"/sys". If it isn't in either, you'll need to copy it onto the SD card, into the /firmware folder, from the 3.4.6 zip file.

If it is in the /firmware folder, send M997 S1. If it is in the /sys folder, send M997 S1 P"/sys/DuetWiFiServer.bin". This should flash the firmware to the Wifi module. Then send M552 S1 and see if the WiFi module turns on.

After that, you may need to set up the WiFi again. See https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-5-connect-duet-to-network

The .bin is in the SD card but the command I sent didn't produce the expected result

droftarts

@genioluiz7 The last command you sent was M552 S0, which tries to turn the WiFi module on but in idle mode. You need to turn it off again with M552 S-1, then run M997 S1.

@genioluiz7 Can you comment out the M552 in config.g? I think it's stuck trying to start the WiFi module. Then reset the Duet, connect via USB and serial terminal, then send M997 S1 without sending any other M552 commands.

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
