SOLVED DWC connection/ SD card disconnections

  • hi,
    my printer lost connection suddenly after editing the config file and reset the board.
    first, i was not able to connect through the web.
    so i connected directly with usb and check m552 at YAT terminal, i got it to work under my requested IP.
    now i able to connect the web but every time i tried to update the config file i loose my connection and my IP (checking again with YAT)

    im not able to move axes or anything and my tool/additional axes and all my config is not applied to the board.
    the SD still show his files but almost any action cause disconnection without able to connect again.

    this was included more weird things such as:

    1. YAT working only when SD is off and only when the board power(24V) is off.- never happened to me
    2. web show printer "busy" when only connects
      and more..
      things i tried to do:
    3. update firmwares.
    4. reformatting the SD card
    5. change SD card

    all with no help i mange to connect with the web but nothing is moving and every reset i lose my connection.
    appreciate any help

  • sounds like a syntax error in you config file, which you should attach

  • @bearer said in DWC connection/ SD card disconnections:

    tax error in you config file, which you should attach

    ok tnx
    i wasn't Familiar with this guide. I'll stick to that from now on.

  • @bearer said in DWC connection/ SD card disconnections:

    nds like a syntax error in you config file, which you should attach

    still not working for me.
    I will try to refine the problem:
    the board only able to connect YAT on pc when it power is off.
    i need also to eject the SD card otherwise im getting a disconnections + wierd warnings:
    ![alt text](10b6a1b1-c006-46e7-9c6b-cad852c32575-image.png image url)

    than im able to get him work on the specific with M552.
    ![alt text](c4561231-1a2d-4137-8de7-fd7607d10592-image.png image url)

    in here im able to connect with chrome to the specific IP but i get an error that tells me SD card is not insert.
    ![alt text](e0293c0c-38a2-47c8-9deb-3ca2acccf8b0-image.png image url)
    than i insert back the SD card to is slot and send m21 command(see picture above).

    now, im able to connect and see the web interface,
    i power the Vin for the board and im still connected, see the SD files in their place and everything looks good.
    after Vin supplied i see printer "busy" on dashboard with no command sent
    ![alt text](b3bb8a0a-2666-42df-8412-12b1e90ebddc-image.png image url)
    so the printer cant get moving cause it busy.
    each time i will try to change config file save and restart the board will disappear and i back to start.
    in addition the printer will lose connection by itself and disappear as well.

    even tried to get my printer a static address still with no help.

    appreciate your advice thank you before head.

  • a lot of white space and long lines, any errors if you run M98 config.g ?

  • @bearer said in DWC connection/ SD card disconnections:

    M98 config.g

    no errors.
    only missing p parameter (m98 pconfig.g)
    meanewhile im not sure what cause the disconnection. i downgrade the firmware version(all) again and it suddenly work well so far.
    i saw post with the same problem and same not sure solution attach here:

    it maybe in house network problem but with all my action im not sure which made it work.
    thank you for advice i will improve my post techniques.
    for now i close this thread.
