sd card corrupted
-
hello,
My Duet2 wifi is not starting up anymore, after unplugging it and plugging it back in.Usually, I control the Duet through a PanelDue , but the PanelDue now showing "Connecting..."
then i remove SD card and check it's not even detected via USB.
and on board DIAG LED will be on permanently. i go throw this link

but can't understand why this happened. -
@R006 Sounds like the firmware has been erased, if the DIAG LED is on permanently.
However, if the SD card has also been damaged, it could be you have had a short circuit, possible VIN to 5V or 3.3V. The SD card and WiFi module usually take the damage first, before a short circuit damages the MCU.
I suggest:
- Connect via USB only (no PSU power)
- Check that you are getting 5V and 3.3V (LEDs should be lit)
- try and flash firmware to the Duet over USB using Bossa: https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#fallback-procedure-2
If the SD card can't be read in your computer, you will have to make a new one. Hopefully you have a backup of your config? See https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

Look in sys on the SD card and see if config.g or config.bak are still there. If not hopefully you have a copy stored elsewhere. If it is missing look in your macros folder and see if you have a file called 2_test_completed. If so delete it.

Thank you for a quick response.
I would like to re-flash the firmware, but both the sdcard & wifi module heat up a lot, so will the SD card again corrupt again?
a) IS there a way to repair these either by sending over OR if i can get similar modules to solder?
b) When I connect via com port, board is not being detected, to flash via Bossa.
Any suggestions?

@KenW I lost config.g file few times too.
most likely this is going to be a problem with his printer -
@Aurimas Yes, after reading his newest reply it does sound like something worse.

@R006 That doesn't sound good. Unfortunately, it does sound like there's been a major short circuit, and it's taken out the SD socket, WiFi and quite probably the MCU too. I don't think it will be viable to repair. I don't have any insight from your description to understand what caused this; you said you unplugged it and then plugged it back in. Faulty PSU? What caused you to unplug it?

@droftarts
Thank you for your response.Means you say i can't use the board

If the DIAG light is on with no SD card inserted, most likely the firmware has been erased. I would disconnect everything, remove the Duet from any enclosure, and test it on your desk with only USB plugged in.
Connect via USB only, and check that the 5V and 3.3V LEDs come on. Make sure to manually erase the firmware (with the erase jumper, see https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#all-other-duet-boards), in case the firmware is corrupted and causing the board not to start properly. Check how hot the SD card, WiFi and MCU are getting. Check if the board is being seen by your PC (device manager in Windows, system report on MacOS).
If the board isn't being seen on the USB port by your PC, and things are getting hot, it's most likely that the board has failed, and is likely to be uneconomical to repair. It's hard to say what caused it to fail, though the SD card and WiFi getting hot does usually mean a short of VIN to 5V or 3.3V. If you want to post a good, sharp, high resolution image of both sides of the board, we can have a look for failed components.
