Duet 3 v1.0 Fault on SD slot

  • Hi,

    Switched my machine on this morning and was unable to connect..did the usual check still nothing noticed no network activity on the board so erased and and opened bossa installed firmware install all OK but still no network activity so connected a Pi and network comes up
    and I can connect as usual through the Pi but as the Pi is not working with my board not much actual use the slot has always been a bit of a fiddle with it not latching 1st time but wasn't really a bother as don't remove the card that often.

    Any Advise?


  • administrators

    please connect over USB (with a terminal like YAT) with an SD card in the socket and send M122

    @Carlo said in Duet 3 v1.0 Fault on SD slot:

    SD card 0 detected, interface speed: 12.5MBytes/sec

    Although that is not a great speed it does appear to be working. please post your config.g thats on the SD card.

    Its saying SBC mode so is the Pi connected? I wonder if you get a different response with the Pi not connected.

  • Tony the Pi is not connected
    and it was working yesterday in stand alone mode

    @Carlo Thanks

    So when connected in YAT, with the Ethernet plugged in if you send

    M552 P192.168.0.25 S1

    Does it work as expected?

    Another test is to send M665 with no parameters and see if the correct ones are displayed back.

    Basically trying to confirm if the SD card it being read or not.

    Laos if you have another SD card it would be worth testing that.

  • @T3P3Tony

    Response from YAT

    M552 P192.168.0.25 S1
    Ethernet running, IP address =

    Error: M665: M665 parameters do not apply to Cartesian kinematics

    Still can't connect:
    Your Duet rejected the HTTP request: page not found
    Check that the SD card is mounted and has the correct files in its /www folder

    First thing I tried of the usual thing was swap the card with a backup of all the folders
    Before I re-flashed the firmware

  • Moderator

    It definitely seems like it's not reading the SD card. Not executing the config.g and can't read the /www folder.

    Can you try sending M22 followed by M21? This should unmount and remount the SD card.

    Also M122 P104, which should try to measure the write speed of the SD card.

  • @Phaedrux said in Duet 3 v1.0 Fault on SD slot:



    Yat output of M21/M22

    SD card 0 may now be removed
    Error: M21: Cannot initialise SD card 0: Card is unusable

    I've tried a third card which this is output against, weirdly the SD slot is now latching 1st time?.

    M122 P104
    Error: Failed to create folder 0:/gcodes in path 0:/gcodes/test.tst
    Error: M122: Failed to create file


  • Moderator

    When and where was the board purchased? There seems to be a fault in the SD card slot.

    Can you post close up photos of the slot insides and the solder tabs?

  • @Phaedrux

    Yeah Pic to follow
    08/04/20 E3D


  • Moderator

    Sorry, is that August 4th or April 8th? Not that it matters, either are within 6 months.

    You can contact E3D and initiate a warranty exchange. Use this thread as authorization. I'm not sure what the current Duet3 stock status is due to the current manufacturing issue with driver diodes, so there may be a delay on replacement. At least in the meantime you can use SBC mode.

  • @Phaedrux
    LoL no I can't use SBC mode it has never worked "under investigation"

    IMG_1617.jpg IMG_1611.jpg
    Best I can get on my phone

    I can't see anything obvious with the slot or pads?


  • Moderator

    Right: https://forum.duet3d.com/topic/16191/duet3-pi-dwc-freezing/31?_=1597246408031

    All the more reason to swap it out. Something is amiss.

  • @Phaedrux

    Thanks as always appreciate your help.


  • Moderator

    It sounds like FW 3.2 beta1 is arriving shortly (maybe this week), if you still have the board when it lands, perhaps you can test it to see if it has an effect on your other SBC issue.

  • @Phaedrux

    E3D is out of stock so I'll keep hold until I've tested 3.2.1beta may be helpful.


  • Moderator

    Do you happen to have a different pi to test SBC mode with?

  • @Phaedrux

    Yeah tested it with 3 Pi's 2x 4b and 1 3b+ all exactly the same result with nothing else attached and even tried a new 26 pin cable still the same.

  • @Carlo
    The freezing I sorted by not using duetPi and just adding DSF to another distro but thats a far as I could get I could do everything but print ..just went nuts on the purge line or first move
    actually damaged my print bite sheet rammed the head in to the bed bent the heat break
    but same files Iv'e printed many time in stand alone

  • i didn't read the whole thread i'll admitt, but if you want to verify the individual parts that make up the connection between the pi and the duet this old-ish thread has a ton of information on where to go digging https://forum.duet3d.com/topic/15551/duet3-pi-dcs-is-unavailable-after-wiring-24v/119?_=1597267914698

    (and if not, disregard:)

  • @bearer

    Thanks bearer I was following the thread at the time I did check continuity and chris did manage to recreate an issue I was having so expect there would be a fix at some point
    though at the time it was still freezing my issues which are many but with the duet even weirder and may not have been software or communication between the 2 as it ran as expected until a file was loaded everything else perfect probe, mesh G1's all extruding, heaters maybe a buffer/memory conflict/issue ?

  • Moderator

    @Carlo These two pins of your SD card socket do not look well soldered:
    Screenshot 2020-08-13 at 14.50.20.png
    Can you take a picture of the socket from an angle across the board, as shown here https://duet3d.dozuki.com/Wiki/SD_Card#Section_SD_Card_Socket


  • @droftarts

    Hi Ian,

    Sorry the board went in the mail run today wanted to keep it a while to test 3.2 beta 1
    plus it is out of stock...but you get 7 days for return once they issue a returns # and I may have no access to office or workshop due to another possible 2 week lock down in my area

    all the pins looked to be well attached and no oxidation all the contacts look ok..bit hard to see inside the slot

    Image I took yesterday from a different angle.


    Dunno if it is of help.
