The state is playing, but showing nothing, Is that true?

[craigyk]

yes, that is what it looks like… no errors or other indications of something being wrong:

I'll check what has been changed from 1.8.3. Is that the previous version you have used?

[craigyk]

Not 100% sure, but I think so. It was the most up-to-date release prior to this recent update

If you don't stop it, how long would the black sceen keep on?

[craigyk]

so far as long as I keep it going… it doesn’t seem to think anything is wrong, feel like the app might even be receiving video data and just not displaying it.

Same issue here. Black screen on app and Bambu Studio. Usually when print stops the camera shows up again.

[bambu123]

Do you have a Windows PC, Can you play and check how it performs on a Windows PC? Is it normal to watch LIVE on a mobile phone?

Did you turn on timelapse when printing? if so, please check the timelapse video.

Or check the record video on sdcard.

[jmxp69]

Switching to lan only mode appears to solve it. I just formatted the card, so cannot check timelapse.

Failure occurs on 2 macs, windows and app.

I think this is a printer-related issue, so I need a printer log. could you help to create a ticket and upload the log (https://wiki.bambulab.com/en/x1/troubleshooting/upload-log).

[jmxp69]

I've switched to LAN mode and am in the middle of a print. When it's over, I'll switch back to online mode and see about submitting a log.

Well, thank you very much.

[jmxp69]

Ticket and log submitted. 100% can replicate: LAN Only Mode camera works on 2xMac, 1xWindows and 1xiPhone App. LAN Only Mode turned off and I get black screens on all devices.

OK, we'll check it soon. Can you please give me the ticket No. here?

The problem is the same "latest release makes connecting to camera less reliable". I understand the hardware may be different, but there was a firmware update a few days ago and now "connecting to the camera is less reliable".

Studio logfile timestamps did not exactly match the printer timestamp. I uploaded Studio logs before and after the printer logfile timestamp. The files I uploaded are the closest I could find to the printer files.

From the Studio logs, it can be confirmed that there is only a problem with the remote video connection. It is a bit troublesome to troubleshoot. You need to provide connection-related logs. These logs are not output by default. You need to create a "tutk_log" subdirectory under the log directory to output them. These logs will include your device IP. It is recommended to send them to me via email.

%APPDATA%\BambuStudio\log\tutk_log

When you create the "tutk_log" directory, you need to restart Studio and reproduce the problem. It is best to wait for a longer playback time, more than 1 minute.

In LAN only mode it works. With LAN only mode off it has issues. Today it's working in both modes. It's not my network connection. It's something between the camera port and the app port excluding my LAN/WAN connectivity. i.e. The issue is upstream--your cloud service somewhere. I've removed/re-added the printer multiple times. I've rebooted the PC, Macs, and Phone. I've done all the Tier 1, Tier 2 scripted processes and have invested more time in this than I really want for a commercial product.

On the surface (without a netstat from the printer or app) the fix seems obvious: Offer local stream port for app/desktop. If printer is on lan and app can see it, allow direct connection to stream. Allow the camera local access without killing the app features. Right now if I didn't want the phone app to work, I'd have switched it to LAN only mode and been done with this. Video stream is slightly less annoying in that mode too.

[craigyk]

I enjoy watching the printer perhaps a bit too much, it’s my zen place.

On another note, the iOS app seems to still show the camera reliably- but the Bambu Handy app hasn’t been updated as recently as Bambu Studio.

I can report that without updating my MacOS Bambu Studio, the cloud mediated video connection is working reliably again- perhaps this got fixed on the server side?

I think so too. Mine magically starting behaving yesterday. It was highly unreliable when I added my initial comment and for the last 24 hours it has been fine with no updates on my side including PC/Mac and Phone.

[jmxp69]

And today we're back to black screens. Zero changes to app/desktop/mac. And obviously my network works as I'm entering this note.

Do you have any "tutk_log" for me ?

[jmxp69]

Added to ticket

[jmxp69]

After the print completed, the image showed up.

[bambu123]

Added to ticket

Please add all tutk_logs to the ticket. For every instance of Studio, there are three files.

[jmxp69]

In the future, you should be explicit about what logs you want. The 2nd/3rd logs from that session are no longer in the folder. However, I'm starting a new print right now and it's doing the same thing. I had video before I sent the job to the printer, and after sending the job to the printer, the screen went black. After a short wait, I pressed the play button and saw "loading" on the right. Then loading went away, the screen remained black, and the play button turned green again.

I will upload three logs to the ticket: 27760.

The job has been running for more than 1 minute now and I still do not have camera.

The green button has self toggled between grey/green a couple of times.

Status is sweeping x/y mech.

Status is cleaning nozzle tip.

Printing Progress is 23%

Screen remains black

I will stop the print and upload logs now.

Upon cancelling the print, the camera displayed the print table. Sometimes it does this, most of the time it does not.

[jmxp69]

Uploading logs fails on your ticket system.

[jmxp69]

Tried on different machine with different logs, still fails.

Sorry, I didn't explain it clearly. From your detailed description, it seems that the printer turned off LiveView during printing. In fact, the printer does turn off LiveView when starting to remotely download the model, and then opens it again after the download is complete.

I asked our colleagues on the printer side to analyze the printer logs in the ticket again.

OK. Please continue to use it, and if you have any questions, please continue to report them to us.

[bambu123]

@jmxp69 Reply from our colleague on the printer side: There is a memory leak issue in the current version of A1, which may cause the inability to generate liveview images. The current suggestion is to restart the printer. The memory leak issue will be fixed in the next version and can be resolved.

We are very sorry for the inconvenience we have caused you.
