How would I get access to buy a refurbished board?

@droftarts
I bought it from RepRapWorld pretty much exactly a year ago, but I only actually installed it for the first time last week. The week before it still worked perfectly fine as I tested it.
I can't tell if there are any issues with the contacts, they seem to be looking fine to me at first glance.

I have seen posts mentioning some wiggle room with the SD card, I have noticed that with mine as well, but with no change apparent.
I'll try getting those contacts cleaned and see if that helps.

Thank you for your response!

I formatted and populated the card myself, worked perfectly fine for months before. SD card still reads fine on PC, made a backup just in case, but even changing the partitions on there a little made no difference for the Duet.

I bought a Duet 3 Mini 5+ directly from RepRap a while back, and tested it successfully, had no problem accessing the web interface. Now for some reason, it's reporting issues with the SD card.

M122 shows the card still detects, inspecting the card with a PC shows the SD card perfectly fine.
The speed reported is "0.2MBytes/sec", which according to https://duet3d.dozuki.com/Wiki/SD_Card#Section_Troubleshooting_SD_Card_issues might indicate an issue with the SDcard slot, or the processor. M21 somewhat expectedly fails to remount.

Is there any further diagnosing I could do? The warranty period has since run out. Is buying a replacement my only reasonable option?

First time on this forum, thanks in advance!
