No more video signal

Sovol SV06 ACE
1

Hello,

Do you have any idea why, even though I just finished printing without any problems, Mainsail is now reporting that there is no video signal on the camera?

The USB cable is not damaged.

Thank you in advance for your help.

The ACE is Klipperized, so check your CrowsNest log file either on the screen on via Fluidd.

You can also use the top right controls to restart crowsnest while the prints running without any risk, which will fix any temporary glitch or let you change the settings (which you also find in the CrowsNest config file) on the fly.

Thanks for your quick reply.

After you read this log file, can you explain to me the issue?

BTW, the camera is working again.

Very weird, the date time in the log file is different of the present date time.

Sadly no, that doesn’t show us the answer.

You have two lines in the log for today, starting ustreamer on video0 and its completion.. and nothing logged before that till mid 2023. You’ve likely just got it either not debugging mode or clearing its logs daily since its original factory config.

You can change this in the config file;

[crowsnest]
log_path: /home/klipper/printer_data/logs/crowsnest.log
log_level: debug                      # Valid Options are quiet/verbose/debug
delete_log: false                       # Deletes log on every restart, if set to true

If we are lucky after changing this and just restarting Crowsnest it’ll show the issue. But its not a sure thing.

Thanks anyway for your help.

The most important thing is that it’s working again.

The next time it breaks down, I’ll change the camera. I noticed that the LED on this camera stopped working when I lost the feed. Maybe it’s a hardware issue.

Have a nice day.

The LED likely goes out any time the camera isn’t being told to record, so don’t take that as an indicator it was the cause of the issue.

I don’t think so.

I’m not totally sure, but it seems to me the led is always on at the same time of camera is operating

Sovol leaves the internal clock on UTC. I assume so they don’t have to add a timezone setting to the printer UI.
