Ultimaker S5 camera stops working after a while

Recommended Posts

Posted · Ultimaker S5 camera stops working after a while

Hello,

 

our Ultimaker S5's camera stops working after continuously streaming for a while, about 4 to 7 days.

After it stops working, accessing the stream at <ipaddr>:8080/?action=stream or <ipaddr>:8080/?action=snapshot loads forever without any image data transferred.

mjpg-streamer reports no errors, other HTTP API endpoints still work. After restarting mjpg-streamer it works again, until it doesn't.

I have found this issue jacksonliam/mjpg-streamer/issues/100 on a fork of mjpg-streamer describing the same problem.

 

The printer is running firmware version 5.2.8.20190320 but this happened with previous versions too.

 

Here is the most recent log, but there are no errors. The stream stopped sometime on the 31st of March:
