UM3 and Cura Connect video problem

Recommended Posts

Hello to everyone,

since a few days I own a UM3, so far working fine, but I'm having an problem with the built in camera, or better the software to access it.

Maybe the fault is the typical f40 (sitting 40cm in front of the computer).

UM3, firmware, connected to wifi, IP lets say assigned via DHCP.

If I open in a browser I get a connection to cura connect. But I will not get a live stream from the camera, neither on the print job page nor on the printer page, because as shown on the screenshot cura connect seems to use internal IP127.0.0.1. (localhost?)



If I click on the camera icon on the print job page the popup for the video opens, but stays black.

The explore function of the firefox gives the following HTML phrase with the wrong IP as well.

<img class="video-stream" style="width: 600px; height: 450px;" src="">


Typing I get a stable video live stream.


Is this a wrong setup by me or a bug?

Thanks a lot for any help,

Sometimes the issue is due to mismatched settings between Cura and your machine. Try deleting your machine profile and adding it back in. This will be under Settings-->Printer-->Manage Printers. Once that is done you should be able to connect your machine again to confirm if the live stream is no available.

If that doesn't work, try doing a Cura Connect Reset in the printer menu and/or hook it up via LAN to see if that changes anything.

Thank you very much Priddy,

I had already deleted the machine profile and added it again several times.

But the reset of the Cura Connect data in the printer itself solved the problem! Very helpful!

@nallath: Thanks as well, but I have no idea how to make a dump, so I'll go back to the manual first. Still have a lot to learn about this machine ;)

Regards, Tom

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
