Camera not working after latest firmware

Recommended Posts

Curiously my camera has not been working since the last firmware update. 

 

So after some poking around I did a few things. 

 

1) Does my Ultimaker 3 Extended have a IP address (yes)

2) Can I connect to it (yes)

3) Can I view the live stream using the http://<ip_address>:8080/?action=stream (no)

4) Can I view the snapshot of the camera at http://<ip_address>:8080/?action=snapshot (no)

5) Reset cura on the machine (done) Still can't see camera

6) Restart machine (done) didn't help

 

I've also left the machine unpowered for a while (unplugged) and that didn't help either. Although I did have to re-associate the machine to the print group. 

 

I can't seem to connect to the camera from any of my PC's nor my iPad / iPhone. 

 

Ideas? 🙂

Blank screen from the "Monitor" tab in the App. From the web page when you to the view print jobs, and click the camera, it's a black square and no image. No errors no warnings. Just no image. 

 

iOS app shows a black screen and will time out after a moment with a camera icon and a line through it.

Can you dump the logs (especially after a reboot) to the USB stick and upload them?

From the information you gave,  I think the MPEG streamer fails to load due to not being able to find the camera hardware. This might be caused by a simple loose cable, so could you check those?

I'm having the same problem, though, I just got my new Ultimaker 3 yesterday.... Went through the network connection steps with the app on my iPhone.  Everything seems to be working except for the camera, which is behaving just as the OP described.  I've attached a few screenshots from my phone of the behavior if it helps.

Here's the transferred logs. https://we.tl/c7MQx4q8C4

Unfortunately not much information in them; also seem to be missing some files.

Is it possible to do a reboot after a print finishes, then immediately after reboot dump the logs?

That should show more information on the booting up process being executed.

@jimmieshear from the logs I gaterh that mjpg streamer is running fine:

 

Jul 11 03:43:19 ultimakersystem-ccbdd3004dc8 mjpg-streamer[246]: MJPG-streamer [246]: serving client: fe80::c1c:d4c4:d08c:3146%wlan0

Jul 12 02:39:33 ultimakersystem-ccbdd3004dc8 mjpg-streamer[246]: MJPG-streamer [246]: serving client: 10.0.1.50

 

If you really can see the image directly using the printer API, then I think the problem is with the camera part: is the lens clean and visible, check the housing of the camera.

 

The chance is small, but it still can happen, that the camera even tho it is detected by MJPG streamer, is broken.

Looks all good. Nothing in the way, no poop on the lens. Housing looks fine. One thing I can't find an answer to is how to check this elusive "Camera connected via usb" question I've seen come up in other threads. How do I make sure the physical connections are solid? I could tear the printer apart to figure that out, but if there's a nice document then that would be awesome 🙂

Actually, I got it working.  I ended up resetting the Cura Connect settings by the System menu on the printer and that fixed it.  Everything is working great now

 

Probably a stupid question but how do you reset the Cura Connect settings? In system menu I don't see a tab "Cura Connect"...

Interesting - after resetting my Cura Connect settings my problem is fixed as well. I thought I'd done that once already, but I guess not.

 

EDIT: 2 hours later, we're back to no video again. I've got a longer print running so it'll be Wednesday before I can pull logs again.

This morning I noticed something weird. During the print I had running yesterday, the camera wasn't working. I came in this morning, removed the parts and set up another print as usual from Cura. I started the print and the camera worked again. Briefly. Most of the way through the auto bed leveling process the camera feed cut off again.

 

So there's that. This is ~6 hour print, I'll pull logs again after it's complete.
