Duet Maestro cannot mount SD card

martijnschouten

My Duet maestro suddenly stopped accepting my SD card. If I run M122 I get:

Free file entries: 10
SD card 0 detected, interface speed: 15.0MBytes/sec
SD card longest read time 0.5ms, write time 0.0ms, max retries 0

If I run M21 I get:

Error: M21: Cannot mount SD card 0: no FAT filesystem found on card (EXFAT is not supported)
[ERROR] Error: M21: Cannot mount SD card 0: no FAT filesystem found on card (EXFAT is not supported)

I have tried formatting two different SD cards, the 512MB one that was delivered with the board and a 8GB one that I had lying around. I formatted them both as FAT32/FAT16 using windows (not using quick format) and using the official SD card formatting tool. However I keep getting the same error...

Is my board broken or am I still doing something wrong?

When and where did you purchase the Maestro?

Can you post a photo of the solder points on the SD card slot? Close up, well lit.

I ordered my duet on 26-04-20. This is picture from my board.

The fourth joint from the top looks a bit sketchy. Will try reworking that one tomorrow.

You're pretty close to warranty. I'm not sure what the current stock situation is for the Maestro though.

If you're comfortable with soldering give it a shot.

I checked the stock with the reseller where I bought the board; It is sold out.

I reworked the solder joints. I'm pretty sure they are connected properly now, but I still get the same error.

@martijnschouten, which country are you in?

I'm in the Netherlands, I bought my duet from 123-3d.nl. But I already had an A4403 that started to smoke and I used my warranty to get a replacement board for that one. But in the meantime I ordered some new A4403 chips, so now I have soldered one of those new chips on the old one and now I can print again.
