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:

It is an old problem which still exists. After some time, can be days, sometimes weeks, the stream is not working anymore. A Cura Connect Reset via the printer menu helps to recover the stream again.

We are having the same problem with our new S5 too. The reset of Cura connect on the printer fixes the camera, but only for a short time.  Never have a problem sending prints over the network to the printer. It is a hard wired network. Not using wifi

Yes it is not depending how you have connected the printer and only the video stream is affected.

 

UM3 has the same issue, so it is not isolated to the S5.

Thank you for your replies.

Reset of Cura connect also resets all the analytic data, so we do a reboot of the printer. 

Is the video stream problem related to an unstable connection?

 

I have one display constantly showing the webpage "/print_jobs".

Will printing the printer connection looks very unstable, every 1-5 minutes its is unavailable for 1-3 seconds.

Is this a part of the same problem?

Hi. Are there any news about that topic? We have 3 Ultimakers and the webcam on all printers stop working after a couple of hours.

It seems not ...unfortunately. Is there an easy way do downgrade the firmware? I just find the actual firmware to download.

Yes, absolutely but requires removing the bottom cover.  Talk to your reseller.  For a while they would only let you downgrade UM3's and S3s because the S5 has deadly  voltages inside but if you promise to be careful  and demonstrate competence you can downgrade S5 as well now.  They really really really don't want you to kill yourself.

 

You will need a micro SD card.  Here are the general instructions but only the resellers know where to get the images:
