Blank Page after update of Duet Web Control



  • I just updated my duet web control and now all I see is a blank page. The tab at the top says Duet Web Control 2. Suggestions???

    It sounds like maybe the update didn't proceed properly.

    First check with a different browser to see if it's just a browser issue. If it still doesn't work, I would pop the SD card into a PC, and manually replace the /www folder with the contents of the DWC 2.0.7 zip file.



  • @Phaedrux I did try the different browser still same issue. Pulled SD card and loaded a fresh download of the DWC 2.0.7 to the card into the /www folder and still same issue. Blank screen

    What board and firmware version?

    Can you connect via USB and verify that it's actually loaded up?

    M115 will give the firmware version.
    M503 will try to read the contents of config.g to verify that the SD card has loaded config.g properly at startup.
    M112 will give a diagnostic report.



  • Maybe add M20 S2 P"/www" to the list?

    And if everything looks good, the developer console in f.ex. chrome has a network tab to help identify issues as well.
    (in chrome hit F12 key to bring up the developer console in a new tab then type in the url for the duet)



  • @Phaedrux So it will eventually load after about 15min and everything seems to be ok. Then I wanted to see if it was fixed so reloaded the page and we are back at the blank page

  • @bearer what am I looking for in the developer console? I have it open.



  • This post is deleted!


  • @Phaedrux I also seem to have just a ton of files in my system folder now. I have never seen this many before:

    page 1.PNG page 2.PNG page 3.PNG

    Looks like you might have accidentally placed the contents of the dwc zip file in the /sys folder instead of the /www folder.



  • @Phaedrux Wow super rookie mistake.


  • Moderator

    no big deal. You have a backup of your SD card from before you started updating right?



  • @Phaedrux right...... No but I guess I need the practice and the lesson.



  • @Phaedrux fixed and fixed, comes up no problem now. Thank you
