SD Slot problem
-
I got my Duet WiFi version 1.19 running on Duet WiFi 1.0 a couple of days ago and have been trying to get the settings right.
first i got some wifi disconnect errors but i did not think much about id at the time, just figured i got a bad reception on my old spare tablet.
The it just stopped mid print and the whole thing just froze. Restarted by cutting power but it would not start again.
So after many tries i read something about disabling the wifi by putting the SD card in the computer and uncomment the command to start wifi i did that.
After putting the SD card back i got it to work again by manually activating wifi. So i try to do the same print once more. Same problem but much earlier and i was still able to access the webpage and it said that it couldn't read the SD card. Tried the SD card in the computer and it works. But still i got a brand new SD Card and copied the config over to it. This time i had a real problem getting it to start again. but it came online for a short time. So after all this it wouldn't start and i couldn't connect trough the usb. At this point i pressed the erase button and followed the instructions to reprogram and update the firmware to 1.19.2 and yes it started again.
Started a new print but this time with serial connected. Worked trough several tests and i desided to make a new test print, but a dry run without filament.
After a while it stopped again but this time i was able to make a M122 command that i listed below.
After this i have made several test prints trying to figure out whats going on and several times i have had Error reading file in the g-code console.
Then i accidentally bumped into the table and it stopped… tried it agan and it seems as it is very sensitive to vibrations... Is there something I can do to fix this myself or do i need to replace the board?Edit: forgot the diagnostic*

My guess is that you have either a bad soldered joint on the back of the SD card socket, or a bent contact inside the SD card socket. Either way, replacing the SD card socket should fix it. How old is your Duet, and which country are you in?
You can test access to the SD card by sending M21 to re-mount it.

Its a week old, and i live in Sweden.
I have continued to try this morning and now it works perfekt. I will try some more before giving in, thinking it could be som dirt inside the slot -
I suggest you also look at the contacts on the back of the socket to see whether they all look properly soldered to the PCB, in case some of them are just resting on the PCB.

I have checked the soldering and it looks fine, took a a picture but i have no idea how to attach it to the thread.
Also i removed the SD card to see if i could see anything odd inside but it locks ok from what i can se.
Tried to start agan and it had stopped work….. pushed the SD Card in and out a couple of times and started and now it works again.
