WIFI connection does not work and COM poe

Mike 0

I have a duet 2 in my E3d toolchanger. But now i face 2 issues.

The wifi does not work anymore !
If I connect the USB cable, i can not find a comport.
Everything was working fine until I tried to change the WIFI to an other network.

So I used:
M587 S"SSID" P"PASSWORD" I192.168.1.14 via the console in the DWC
But I used the wrong IP address. The IP address the Duet should use is 192.168.10.114.
After restarting, I can not connect to the printer via WIFI so I tried a USB cable to connect. But I do not see the com port. I went through the documentation and checked the LED's, and they seem to work fine. Whereby, the documentation tells me the WIFI LED should be blue and mine is Green, but I do not think that is the issue.

Now, is there any way to change the WIFI settings via the SD card. I tried to add the M587 S"SSID" P"PASSWORD" I192.168.10.114 to the config.g. But so far no luck.

Also, I do not find the reason why the USB connection does not work. I tried 2 Laptops, and it was working during the setup of the machine 9 months ago. The Laptop does not find any usb connection. No Port, no unknown device, no error

No that won't work.

Have you been through this guide yet?

What LEDs exactly are lit?

Have you done the erase firmware and reflash with Bossa procedure yet?

@phaedrux Thanks a lot. I did that already, the LED's look fine.
But maybe you see something:

No, I did not try that. Is the firmware on the SD card or on the board ?
I will try to use an old backup of the SD card first.

Is there a manual for the Bossa procedure ?

I’d try a different USB lead. That one looks like it’s more for power only. Also, the Duet appears to have firmware on it, as it initialises the WIFi, and connects. So you should be able to see it on the network router, to get the IP address.

No, I did not try that. Is the firmware on the SD card or on the board ?

The firmware that controls the Duet is on the board’s microcontroller. A copy of the firmware can be kept on the SD card, but it needs to be flashed to the Duet board itself to work.

I will try to use an old backup of the SD card first.

Ideally you need to use the same version of DWC as RepRapFirmware. To recreate the SD card, see https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

Is there a manual for the Bossa procedure ?

As I said above, I think the Duet has firmware on it. If you want to use Bossa to flash, see https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#fallback-procedure-2
For the firmware files needed, read the above link from the top of the page.

@droftarts Thanks for your feedback

I tried 3 USB cable. The one in the video is just the last one I tried.

I thought that the firmware is on the chip and I also think it is running. I only changed the network settings. But that the com port is not working is rather strange.

Well, I do not find the Board in the network and also not on the router. I guess because is used the wrong IP address.

Flashing the Firmware would set everything back would be an option. But i not like to go down this road if it is not necessary.

I will try a new SD first.

Thanks again

@droftarts Funny enough, I used a 4th USB cable, and it worked. I have fixed the issue and it is running again.

@phaedrux @droftarts Thanks a lot.
