Get Camera working

[tommy4111]

Anyone got camera working? I'm running on Windows.

Went through everything in https://github.com/TFyre/bambu-farm/tree/main/docker/bambu-liveview

Not sure what I'm missing.

Some errors I'm seeing trying various ports:

PRINTER_PORT: 8883

As per previous comment https://github.com/TFyre/bambu-farm/issues/111#issuecomment-2169164564, please dont fiddle with the ports unless you are doing fancy port forwarding!

Assuming this is a X1C?

REMEMBER to enable LAN Mode Liveview on the printer

Test if you can connect to SSL Video Stream (and paste the output after stripping sensitive information like printer serial):

openssl s_client -connect 192.168.50.203:322

[tommy4111]

Thanks for reply. I tried both A1 and X1C. LAN mode liveview is enabled.

Here you go:

openssl s_client -connect 192.168.50.203:322

Awesome!

Please remember liveview (high FPS) is only applicable to X1C. The A1 will use the normal jpg streaming (low FPS) route

[tommy4111]

Sorry, so base on this certificate error output, I can't make SSL connection right? Anything else you think I can try?

[TFyre]

Quite the opposite, since you can see the certificate exchange, we know that its working correctly.

Please retry/restart the docker container bambu-liveview-myprinter2-1 since it should be working correctly now.

I'm either getting "invalid data found" or "Error opening input: Connection timed out"

Everything else work, just camera not working.

TCP 8883 <--- this is WRONG TCP 322 <--- this is CORRECT

Please specify the models for myprinter1/2/3

The streaming is ONLY for x1c.

for the A1, you need to use the normal jpeg frames

[tommy4111]

Got it. Thank you so much for your help. I gave up on XC1 for now (only need A1) and A1 is working.

[TFyre]

Dont give up on the X1C 😄

Below is GOOD!!!

openssl s_client -connect 192.168.50.203:322
CONNECTED(00000004)

Below is where it goes wrong... Change the port from 8883 to 322 and it should work
