SD Card failure
-
Hi,
I am having a terrible time getting my Duet 2 WiFi card to work. First a dead WiFi port. Now, the SD card has died. I have downloaded the Duet2CombinedFirmware.bin, and have a replacement SD card, but what do I DO with the .bin file? -
Unless the firmware on the Duet has been erased, you don't need to do anything with the .bin file.
See https://duet3d.dozuki.com/Wiki/Firmware_Overview#Section_SD_card_structure for the file structure needed on the SD card. There is also a link to the SD card image there.

OK, I've found this site: https://github.com/T3P3/Duet/tree/master/Duet2/SD Card Contents but I have no idea how to actually download the files. Clicking on them opens up their contents. There is no download button.
-
My SD card is not recognised by the Duet board, or either of my two laptops. To all intents and purposes, it's dead.
-
does the card show up in windows disk managment? it might just be a corrupt partition
-
Hi, I've had this before. The card is not even recognised by Windows. The only acnowledgement it receives is a message saying that the card is not recognised.
-
So basically, I need to build a new card. I have the card, and I have the files. I just can't figure out how to get the files onto the card.

Format the card as FAT32 (or if needed open the disk manager and create a partition on the card, format it and assign a drive letter)

you should have a removable drive that is accessible under My Computer after the step above, then just copy the files accross.

Download the SD card files as a .zip file as @bearer shows 2 posts up. Then extract the files from that zip file to the root of the SD card. If your PC runs Windows 10, see https://www.simplehow.tips/a/56/how-to-zip-and-unzip-files-in-windows10.
-
(Files other than .zip wil have a similar button that may saw "Raw" that will allow you to download individual files off GitHub, but in this case the zip file is the convenient way to do it.)
-
Hi. I have downloaded the zip file, unzipped them into the root of a new SD card, and inserted it into the Duet board. I switched the power on, but there is no light which comes on to show that the WiFi module is active. And navigating to its IP address results in a time out error message. I'm running out of ideas.

The Wifi was working flawlessly till the SD card died. Do I just copy the files onto the card? Nothing else? How does the board know that boot files are there? Does the SD card need any special partitions or boot files? How does it even know to read what's on the card when it fires up? -
@duncan-rtfm The SD card doesn't need anything fancy. It's just an SD card. The only thing that needs to be there are the folders and the config files. The main system files that the duet uses are located in the /sys folder. Config.g is read at startup and all the gcode commands within it are executed to configure your printer.

OK, it sounds then like my WiFi card has somehow given up the ghost again. What commands can I issue from YAT to verify it is OK and healthy?
-
You can manually reset the wifi module if you have console access via USB, or a PanelDue. Send M552 S0, to disable networking, followed by M552 S1 to enable networking. When you do so, you should see the blue led on the wifi module blink a few times and then go solid when it has a connection. If the light is off, and stays off, that would mean there is a problem. In that case, send M122 to get a diagnostic report. The wifi part is towards the end, and may provide some insight.

OK, Here's what happens...
M552 S0

M552 S1
Turn off the current WiFi mode before selecting a new one

Do you happen to know what main and wifi firmware versions you are running?
