That sounds most unlikely. The test procedure for Duets reads the test file from SD card, so the SD card socket is known to work when the board passes testing. Are you sure that both SD cards are OK - do they work in other equipment? How often are you removing and replacing the SD card in the Duet?
-
Any chance you're using an SD card extension cable?
How are you powering the Duet? If by USB, have you tried a different USB cable or powering it by the screw terminals?
As for concerns about it being a whole batch, I know you got it from us (Filastruder) and I don't believe we've had any other similar reports.
-
I haven't been using an extension cable. The cards are recognized fine by my computer. I'll try using the screw terminals tonight, and see if it makes any difference.

Ok so I unplugged my LCD and now it works. From the wiring diagrams I thought the LCD was in the right connector, but now I'm not so sure.
-
What LCD are you using?
-
I was using the LCD from my Tronxy P802MA kit.
-
no idea if this is a good thing but i turn on my duet wifi with no sd card then off then put the card in and back on and it takes the changes. I am sure there is a better way to do this probably via software but it works for me so stuck with it…
-
I presume you are plugging the LCD into the "LCD" 2x5 connector, and the "SD" connector? That LCD is not yet supported in firmware so its probably interfering. Does the SD card read work fine without the LCD plugged in?
-
I was plugging into the 2x5 connector not the SD connector. The SD card reads fine without the LCD plugged in.
-
Yeah so there must be some interference from that LCD, 20x4 character LCDs are not supported yet either. At least we now know what the issue was!
