SD Card not working

AdrAs

@Norder
I copied the files over and over again so many times that I should have gotten it right just by accident. No, files are definitelly in the right place.

@Phaedrux
I just tried the 16gb sd-card from my other printer which also uses a duet board. Also didn't work at all.
What was also weird is that when I connected the working printer via usb to my laptop the panel due turned on (without an sd-card in the duet).
For my new duet board the panel due doesn't turn on.

I also tried resoldering the pins as you can see in the picture. Pin 1 from the left looks a bit weird to me, I'll give it another bit of solder

@adras is that PCB black?

@jay_s_uk
Yes, it is. Got it from china yikes

@adras
Maybe I broke the firmware, I think at one time I accidentally flashed DuetWifiServer.bin with bossa.

Is there a way to make a complete reset of the processor? Because even after erasing it, my wifi settings are still present. Maybe there's something stuck in the memory somewhere

@adras you are running old beta firmware. Please upgrade to the 3.4.1 release.

AdrAs

@dc42
Still the same with 3.4.1. When I use 3.4.1 RC2 and run M122 I hear the windows device disconnect sound and I don't get any output at all

Failed to reset the WiFi module to factory settings
ok

This is also kinda interesting. Why doesn't that work?

@adras maybe because of this:

"Yes, it is. Got it from china yikes"

@adras try sending M552 S0 before sending M558 S"*"

It's also possible you don't have a proper firmware flashed to the wifi module. Take the wifi server bin from the latest release and try flashing it with M997 S1.

If it still can't read from the SD card, then I think your socket may need to be reflowed.

@phaedrux

M997 S1 doesn't work, because the file is never found. I put one in the sys, one in the firmware and one in the www directory, I even specified the path myself

@phaedrux
WOHOOO finally. Your reflow idea was great. I just used my hot air rework station set it to 350°C and heated the thing up. I saw some vapor/smoke coming (could have been some remaining flux from my soldering attempt).

But now ...

Error: M21: No SD card present
ok

SDHC card mounted in slot 0, capacity 31.91Gb
ok

My panel due is also lighting up now.

Cool, thanks for your help guys

Well, turned out it was something completely different. I just hooked up the board again and the panel due was blank. Suddenly everything stopped working.

It was also weird, that the Serial port changed. The working one was no. 4, the not working one was no.3. Then I thought ... wait a minute ... I've got two usb ports on my laptop, let's use the other one.

Turned out that connecting the duet to one port works, but connecting the duet to the other one doesn't.

I just used a usb tester. On the working port the duet board consumes about 300mA, on the non working port it consumes only 100mA.

And I thought the usb-port survied that 12V incident a couple of years ago. But even if the fuses seem to have recovered, that port is no longer able to deliver enough power.

So the entire problem all the time was having the duet connected to a broken usb-port which doesn't provide enough power.
