UM3 - Camera not working (even after factory reset)

[Macooki 1]

Hello,

 

I've use in the past UMS3 and had no problem see webcam feedback on local network and Digital Factory.

Now on my UM3 i'm unable to see any image on local or Digital Factory.

I've tested directly Cura + on different web browser but i only have a loading screen.

I've followed few topic on this same problem but nothing resolve my problem.

 

- I have a local IP, can connect to local webpage but no image stream

- Keep showing loading with a blue circle moving.

- Firmware 5.3.0

- Factory reset change nothing

- Digital Factory reset, nothing change

- Not working on iPhone app

- Tested on Firefox, Chrome and Edge

- Unplugged printer electrically

 

Thank you!

Have you tried going directly to the stream? That would show you if the camera is still alive and there's something else going on preventing you from seeing the output.

Something is wrong with the camera electronics. In the dmesg.log file you posted there should be a few lines for the camera being detected on the USB bus. Something like:

Quote

[    6.699785] usb 2-1: New USB device found, idVendor=28c7, idProduct=3841
[    6.706554] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[    6.713891] usb 2-1: Product: USB 2.0 Camera
[    6.718304] usb 2-1: Manufacturer: Ultimaker B.V.

 

These lines are missing.
Check the usb cable to the camera. Check both sides, i.e. at the camera and the connection to the cpu board.

Sorry for late response, i was away from my printer.

I've check cable on both end and it change nothing, can I plug the camera module on my PC to test it?

The camera used to be a standard usb webcam, but then they didn't have enough usb connectors on the cpu-board, and the connector type was changed.
I'm looking at the schematics and it doesn't make sense anymore.

It seems to be a micro usb to mini usb cable:

- micro usb for webcam interface

- mini usb for board interface

 

I tried to plug the webcam with a micro usb to usb cable and my PC don't detect it.

When your camera has a (micro) usb connector, then it can be connected to your PC. In my printer it has a different connector, but my printer is an early protoptype.

How to show the image on your pc is another thing which I didn't look into.

I've successfully link the camera module to my PC. I've just plug with another micro usb to usb cable, open Camera app in Windows 10 and switch to it.

 

I've replug it in my printer, restart it and it worked perfectly now!

To conclusion for this topic: I think that plug it directly in my PC reset my camera module. I've tried plug/unplug camera module few times, factory reset my printer but it doesn't do anything. It has worked only after i plug into my computer and replug it in my printer.

 

Thanks for helping me 😇

 

 

EDIT 14/08/2023: I found the exact problem: the micro usb port on the camera module was bent, so as any micro usb port (damn I hate this kind on port) it could'nt connect properly. More precisely, pins inside was bent, so i gently push it back (could'nt really see diffrence visually) but now it worked!
