SD card doesn't auto mount, Wifi module won't auto start

@Macua if a new SD card doesn't help, please send a close up photo of the soldering of the contacts on the back of the SD card socket. We've seen issues with that in the past, although not for a year or two since we changed the brand of the socket.

This is what I get:

M39
SD card in slot 0: capacity 7.86GB, partition size 7.85GB, free space 7.83GB, speed 20.00MBytes/sec, cluster size 32kB
ok

No issues with the card in the laptop.

Cheers,

Yes, but do you have another new SD card to try?

Macua

Thanks for the help everyone.

I’ve tried reformatting a few times with no joy. Just ordered a new SD card so will give that a go tomorrow.

The duet I got second hand off eBay, so it’s quite possible it’s of the generation that suffers from the connection/soldering issue.

My suspicion is that it’s a hardware issue, but new card tomorrow will confirm hopefully.

Many thanks,

Anthony

Well, this is very frustrating. I've got a new SD card, and a replacement Duet wifi 2. I have exactly the same problem, the card is not mounting. Its not running config.g or the runonce.g, so the only way i can set a network up is through YAT manually. I am at a complete loss! The firmware was compiled using RFF config tool, correct version selected. Not sure what to do next?

Can you put the card in your PC and take some screen shots of the root directory as well as the sys directory?

Perhaps the file structure is incorrect.

@Phaedrux

Thanks for the reply. Turns out it’s all working now with the new duet board! I expected the card to mount and run the runonce.g for the network settings. When it didn’t assumed same issue. However did some Googling and found that file doesn’t work (?) so programmed the network the usual way through YAT. Now all working perfectly.

Thanks for all the help. Now I have to tackle the layer shift problem it’s got. No successful prints yet. Does the duet need active cooling?

Never hurts. It depends on how it's mounted and if it's enclosed and how many drivers are being used and at what current, but if you have the means to at least blow a fan across the back side of the board along the drivers it's a good idea.

With motor currents as low as those, you don't need to cool a Duet 2.

@dc42

Just to draw a line under this, layer shift was a mechanical problem, nothing to do with Duet3D...which is simply, amazing. I will start another topic on quality of prints though - my 2014 ultimaker original seems to outperform the Duet with the same hardware, not sure if I can tune it out.
