Reverse input polarity Duet 3 Mini

dc42

Does the SD card read OK in a PC? Have you another SD card you can try?

Which country are you in?

@dc42 The SD card reads fine under windows. I tried a different one, formatted to FAT32, copied the contents and got the same behavior. Are the SD card contents not compatible with the new firmware or should this be independent on the issue of a M21 command? I'm from Germany.

I understand this is a new build, but were you at a point yet where you had previously been able to access the SD card?

@Phaedrux No, I was just installing the board in the printer when the mishap took place. I never was at a point where I turned the Duet on before. Now I tested everything and was able to verify that its still working. However, the SD card does not work the way I'm trying right now. I cannot say if it worked before.

I was shortly able to get it running:

SD card in slot 0: capacity 7.95Gb, free space 7.94Gb, speed 22.50MBytes/sec, cluster size 32kb<\n>
ok<\n>
<\n>
SDHC card mounted in slot 0, capacity 7.95Gb<\n>
ok<\n>
Error: Cannot read file, error code 1<\n>

However, after I tried to access DWC, I got the error message "Error: Cannot read file, error code 1" and after that I wasn't able to mount it again. I was not able to see the DWC from my Browser.

Okay after another hour of testing: No SD card works, only that one time it worked for a couple of seconds. I've read that a couple of other users of the Mini had the same issue. However, after my input voltage reversal I can't be sure if it wasn't working from the beginning or only after that. Seems like I got an expensive piece of junk now without a working SD-card interface. Very disappointing

It could be an unrelated SD card issue. Where and when did you purchase the Duet?

Please contact your vendor and initiate a warranty exchange. Include a link to think thread as authorization.

@Phaedrux I bought it on the 6th of January from E3D-Online. I think it could be a problem with the SD card socket itself, since I was able to very shortly mount the SD card it, maybe some contact problems?

@Phaedrux Thanks! I did this and my return package is already on its way. Thanks for the great service and help.
