Lost Ethernet connection (Duet2 with duex5)

Mike 0

After i had a slight crash during a test with a new Bed.g file to probe 3 point of the print bed for a 3 motor Z axis. I pushed the emergency stop button in the DWC.

Since then i have no ethernet connection anymore. The led's do not flash on the Ethernet port on the duet2.

After pushing reset, i can now connect via usb cable and send commands and get an answer (to be fair i only tried M115)

But even after several on and off switching, the ethernet is still not connecting.

By the way i added in the end of the config.g a LED macro, which normally runs the led strip. But this is also not happening.

Is there any reset? Maybe the board is stuck in a loop?

@Mike-0 It turns out the SD cad is not readable anymore.
when i send M501 via the a terminal software i recive the following message

SENDING:M501
Warning: Macro file config-override.g not found

I will try a new SD card tonight.

@Mike-0 It sounds like it is not running config.g to enable networking, or anything else. If you connect via USB you can test the SD card and slot, and get a file list if possible. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#troubleshooting-sd-card-issues

It's possible that when the crash happened, VIN got shorted to 5V or 3.3V, and zapped the SD card. The SD card socket tends to fail before the MCU. Check if the SD card socket is getting hot before putting another SD card in.

@droftarts thanks.

I could recover some of the files from the SD card via a recovery tool.

Got everything running again.

I will still check the SD slot tomorrow.

Is there anyway to backup all the data from the card, automatically or via a button in the DWC?

The quickest way to back up most folders (eg sys, jobs) is to go to the relevant screen (eg Files > System), select all the files (click the checkbox at the top of the left hand column) then right click on one of the files. You should have the option to 'Download as ZIP'.

Edit: Note this can only download files, not folders. One exception: folders in the Filaments directory can be downloaded.

There are some other options:
RRF configuration file mirroring and management
rrgit
RepRapFirmwareFileManager

@droftarts thanks a lot. I know the Zip download. Cool would be one button. I will look in the other options.

By the way, after changing the SD card to a new one, I did not face the issue anymore.

Thanks.
