R79 looks fine at first glance. My last print was severely underextruded before the failure but i don't know if that has something to do with it

It doesnt seem to detect it under any circumstance. The problem probably lies somewhere else.

I don't think so, the warranty is 6 months right?
Edit: the two on the right do seem a bit less inside the solder than the other ones

it does look like its resting on top a bit but it's not really clear

Thanks for the quick answer!
I have run a M122 and it says : SD card 0 not detected, interface speed: 30.0MBytes/sec
SD card longest block write time: 0.0ms
M21 says a similar error : Cannot initialise SD card 0: Card not found.
I have had my duet board for around 8-9 months i think so i am probably not under warranty anymore.
Replacing the socket does sound good. How do I contact you in regards to replacing it.

Did my sd card reader on my duet wifi die? It doesn't detect sd cards anymore. I have tried reformatting, two other sd cards and putting in new files but nothing is working. It just seems that it isnt reading my sd cards anymore. Is this also a part that is replaceable or will i have to replace the entire board?
