S3 lost connection with DF and Cura


Recommended Posts

Posted · S3 lost connection with DF and Cura



My Ultimaker S3 has lost the connection to the Digital Factory. This issue just occurred today. The S3 was connected and visible before today.


I was not able to add the printer back into the Digital Factory so I upgraded the firmware to 5.8.0. the connect issue still exists.


When I disconnect the S3 and try to connect via the webpage, the webpage resets and printer does not show up. The Printer appears to be connected and the disconnect button is visible. 


My system information

Cura 4.7.1

Mac OS Catalina


I would be interested in your thoughts.

    Please export the printer's logs via the settings menu on the touch screen and upload them here or send them to me in a private message. Hopefully the logs will reveal why the printer is no longer appearing in your Digital Factory.

    Hi Chris,


    Thanks for engaging the Engineers to review the logs. From your note, the printer lost connection with the NTP servers (potentially a network connectivity issue) which then caused the Digital Factory certificates (which are time sensitive) to be invalid.  To resolve the issue I performed a Digital Factory reset from the menu and removed/added the printer back in Cura which resolved the issue.


    Thanks again Chris and the Engineers for looking into my issue. I am able to print and complete my jobs! I appreciate it!
