Great!!! Now we have more points of view of our 3d prints. Thank you Chris.
Happy to help!
Thanks! I find your videos to be the most informative and has helped me a lot. So, you have the first youtube channel I've ever become a member of. Keep up the great work!
Thank for your pledge!
Thanks Chris. About three weeks ago I went through the steps in your video from February 2021 to set up multiple cams and instances. Wish you had this a little sooner! 🙂
Thanks for watching. Sorry I was late. ;)
The OctoPrint MultiCam plugin page should just have a link to this video. This is an amazing video, and after all my searching it’s the only resource I’ve found that fully explains, in more-or-less layman’s terms, how to make multiple cameras work with the MultiCam plugin.
There are some coding gurus and people with lots of experience who have contempt for those of us who aren’t experts. I’ve seen people even in this comments section who fit this bill, saying that 3D printing isn’t plug & play and that if you don’t know this stuff, then basically you have no business 3D printing. There’s no room for that kind of elitist mentality. If it weren’t for hobbyist printers fueling and funding this field, the technology would be nowhere near what it is today.
All this is to say, thank you so much, Chris, for striking the perfect balance in this video, by assuming the viewer to be neither a total ignoramus nor a first rate computer genius.
It’s actually mind blowing how few resources out there actually seek to strike this balance, and I really appreciate you taking the time and care to actually teach people and help grow this amazing field of technology.
Awesome! Thanks for your comment!
Timely and useful, thank you
Glad it was helpful!
Thanks so much for making this!! I even figured out how to hook up my thermal camera !
Glad I could help!
Nice approach , thanks
Glad you liked it!
Glad someone finally made this video!
Thanks for watching. I'm happy to help
Great info glad I watched this video it was very helpful 💯
Glad you liked it
This tutorial worked great!
Glad it helped! Thanks for watching
Great revisit of the topic, thanks ! It's way easier than preparing extra daemons and services manually. The inclusion of the haproxy config is a great addition too, as it allows for dynamic IP, port forwarding, ingress tunnels and such
Thanks!
haproxy is also a must if you use a web-application that adheres to recent protection-standards and has tight CORS headers. Apparently OctoPrint isn't that security-minded in this regard and as long as you use it within your LAN only, I can't really hold that against them. With Mainsail however, I did have to map the cameras into the same host as the Mainsail UI to get them to show in the UI, but having all these camera's with Klipper and Mainsail is probably a totally different video ;-)
Thanks!
Awesome, thank you!
"Overcomplicating" is just another term for explicitly complete! Thanks for the video Chris much appreciated!
Thanks for watching!
Thx Chris !!!! :)
Thanks for watching!
Goddammit! I wish your video came out BEFORE I set my cameras up!! Great work and thank you!
Thanks for watching anyway! 🙂
Great video Chris!
Thanks!
Thanks chris fro Algeria north africa keep it up
Thank you!
I have had my three usb cams set up like this for quite some time. It works great at first, but then the streams drop off one by one. Sometimes a reboot of the Pi brings them back, sometimes not. Drives me crazy. The rest of Octoprint runs fine, so no apparent memory leak or anything like that. I’m guessing it is one of my other plugins that interferes. Great video as always!
Thanks! I see that some folks are going to Ustreamer, I think it is. I wonder if that would help with this? I will have to try it.
Hi, Nice video as always! I'm using a DSLR do you know if there is a way to use it to Monitor the Printer as a webcam when it's not on a Timelapse mode??
Thanks! About the only way I can think of is maybe a camlink or streaming adapter of some type.
Great video!
just one question, so my octopi.txt does not include the same parameters as the one you are showing in the video, it appears to be missing some parts like the #camera="auto" do I just add it? . also I have setup Gphoto with octolapse previously to use my DSLR for timelapses, and now I would like to add my C920 to the pi and use it as the default webcam since my DSLR does not provide a stream and my snapshots are actually saved in the Camera's SD card instead of the Pi. do I edit the octopi.txt inside /boot for using it for the C920 or do I create a new octopi.txt like you did for it and keep the default one untouched? I want the C920 to supply snapshots to my telegram bot since the DSLR won't cut it.
Thanks again for making it so easy to do these things as some of us are not as experienced as you are and struggle to make it happen.
Yes, they changed this up right after I made this video. RPi cam is no longer supported in this way, so it defaults to USB, no statement needed. You can do either, but creating a new file for the C920 might be cleaner. Glad the videos have helped you! :)
Great video as usual Chris, I've learned a lot from all of them.
Thank you so much! Glad you like them!
you have a natural ability to explain and teach. Thank you for taking your time to make these videos.
I appreciate that!
Which Version of octoprint you use? My original USB cam on /webcam/?action=stream (classic webcam) does not work anymore.
Yes, using the newest version. 1.9.3 I think and all the webcam stuff has changes. th-cam.com/video/n9smmmH1O7Y/w-d-xo.html
For the least amount of issues I highly recommend using a mix of cameras. I've run into issues on multple OSs with multiple cameras having the same Manufacturer and device ID on the same USB bus. Also if you are running into USB bus bandwidth limitations you can use USBtop, much like htop, iftop, to find which camera is hogging the bus.
you can use by-path instead of by-id, it works with same brand cameras
🙂👍
@@kazolar Oh my god, thank you! You just saved my RPi-illiterate a$$ about 2 hours of internet searching, if my recent luck with this stuff is any indication. Seriously, thank you!
Edit: Well crap- when I used the command ls /dev/v4l/by-bath, it brings up 7 different strings of data with different index numbers and variations like "codec" or "isp". I'll do some searching and experimenting to see which one works and I'll try to remember to report back here which one worked in case anyone else finds it helpful.
Edit 2: I got it to work by using the device path called "platform-fd500000.pcie-pci-0000:01:00.0-usb-0:1.4.2:1.0-video-index0", so hopefully that's a good reference for someone. I'm no expert, so I have no idea if this is the correct route to go for everyone, but it worked for me.
It is highly recommended to use a powered USB hub for multiple cameras even with a decent power supply for the pi to avoid the possibility of under voltage issues.
Absolutely.
AWESOME video brother. Much easier than the last. One quick question, i am able to view each of the cams thru the URL, and they show in the multi-cam plugin window, but on camera control i do not have buttons to switch between them. Any idea why that option would be hidden? 19:40
Thanks! Huh, that's strange. Do you have any other plugins installed? Maybe another is overriding multicam as far as the control tab is concerned.
@@ChrisRiley Turns out the newest version of octopi has the different camera buttons inside the camera window. Thanks again.
Hi Chris, great video bud. After a big change out to the printer / Rasberry Pi etc etc i came across this video ( for some reason i did not get an alert to the addition on TH-cam!! ) Anyway after a clean install of octoprint i tried following the guide but i am not seeing the part about the Pi Cam in the octopi.txt file you show!! Any thoughts? i saw a comment in the same file about the raspberry pi cam being somewhere else?? Cheers mate
Thank you! That's strange. Run a grep on that file see if it can find it. If not you can probably add the line.
pi@OrangeJuice:~ $ cat /boot/octopi.txt |grep camera=
#camera="auto"
# options to be ignored. Set `camera="raspi"` to avoid these issues.
@@ChrisRiley Thanks Chris I will try that on a fresh install asap.
Hi Chris, thanks for the video, i have a question I am currently running a Raspberry Pi 4 but am about to swap it out for a i5 NUC and run muplitle Octoprint and multiple cams, how many incidences and cams would you suggest I could run? P>S I was planning on running a USB 3 Hub to give more ports as well
my experience as been that on intel mjpeg-streamer only supports one camera per usb host. So you run lsusb to see how many usb controllers the NUC has; I would not expect many.
You're welcome! Not sure how many, I have been able to do 3 printers and 3 camera really easy. I think the NUC can do a lot more, but I have never tested it.
So much easier than what "we" went through the first time back in '19 or so.
Oh yeah!
Great guide, I have been pulling my hair out trying to get multi cameras going. I finally got it working but now the problem is only 2 will come on at the same time. and its random. one boot up will let cameras 1 and 2 work while the next time i boot it might be 2 and 3 working, i cant find a pattern to which ones will come on or why its doing it. any suggestions? pi 4b, and everything is updated.
I have had a couple of people say the same thing. I will have to set it up again and see if I can get 3 going.
Hey dude trying to follow video but it says in the octopi.txt that the locations have now changed so I presume this is out of date because of the latest release ? I can't add an additional camera for the life of me ...
Hey, they have changed a bunch of stuff. See if this video helps you out. th-cam.com/video/n9smmmH1O7Y/w-d-xo.htmlsi=D7Jikq4ocXx337wT
Chris I have a Pi I’m not using currently. How would I set it up to be the Pi that the camera’s (spool cam, bed cam, nozzle cam) are connected to so that I take that load off my Octoprint Pi?
They easiest way would be to setup octoprint like this just with no printers attached. Then on your Pi with printers attached, just use the camera pi IP instead of local host. Not sure of the load savings, but it might be worth a try.
@@ChrisRiley what about MotioneyeOS?
With the newest update that uses pi cams as usb, what needs to change to be able to use a pi cam and a regular webcam
Paul just made a new update to his script. That should help folks get going. github.com/paukstelis/octoprint_deploy
Hmm. Followed this video but port 8081 can't be reached. Wonder if something changed?
By default, a fresh install should have that port open. If you can, start will a new image and go from there.
How about multiple of the same camera without serial numbers to identify them. I had to do something similar to this with my multiple klipper install and assign each machine to a specific USB port, my trigorilla board are not unique.
I have a video coming that uses a script to identify all of this, it can help with the no serial devices.
I have a problem, in output terminal I didn't find the path 'dev/v4l/by-id'
There might be a problem with the cam you are using. If you tail the messages log, unplug then replug the camera, does the log know that it's there?
sudo tail -F /var/log/messsages
Im trying this with only one camera and cant get it to work. running the Octopi on a VM inside windows 10. just cant figure out how to enable 1 camera... help
What virtual host are you using? Likely a virtual device issue.
What tool are u using to connect to ur pi?
Putty, here is the link. www.putty.org/
You made this just in time for them to push the camera-streamer branch. How do we go about the multicam setup now? Also, could you go over the by-device setup. I have two ELP cameras I'm trying to use that both come up with a singe instance of the same ID.
I'll see what I can do!
@@ChrisRiley or maybe it needs to be by-path, not really sure
Try this video. Paul's script should take care of all of that.

Hello Sergio, thanks for stopping by!
Good video, but how many cameras is enough?
I need ALL the cameras Dave!
how to set multiple camera on octoprint (running on mini pc - proxmox) ?
It should work the same way I show here.
Is there anything special that needs to be done when using webcams on a powered USB hub? And I've tried to follow along with your instructions as best I can but still haven't been able to get my 2 webcams working. Both are Logitech with USB connections. I've tried the hub and plugging them in directly to the Pi with no joy. I can only get one working at a time and can't figure out the rest of it. I don't suppose there's a complete copy of the text files used to make all of this work?
The hub should work with this just fine. Can you see the cams with the ls /dev command I show? If so, this should work. I can get you copies of 2 files I have on hand. drive.google.com/drive/folders/1j3yYkHEFrqr1BurIVbK-BBRVTWgaVBd1?usp=sharing
@@ChrisRiley Thanks for getting back to me Chris. Yes I can see both cameras but can't get both to work. Even when I plug each directly into the Pi. I'll give your files a try and let you know.
@@ChrisRiley No joy Chris........I can't imagine what I'm doing wrong.
I have a arducam imx519 that I can not get to work.. Any idea?
Sorry, I've never tried one of these cams, but they look interesting. Maybe they will work with the new camera stack? I am testing that now.
@@ChrisRiley I got it to work with manual focus. Can I send you a link from GitHub/octopi forum. Flipside101 is the guy that figured it out.
So as of now the octopi.txt file says, 5/13/2023
### Heads-up: The "input_raspicam" input module of mjpg-streamer is no longer supported.
### Raspicam support is now available on the "input_uvc" module.
There is no camera auto line in it either.
What's this about? Fresh download and install of octopi yesterday. Seems your new video is out of date already, LOL.
EDIT: Yea i got this all setup with four cameras, one raspi V2, one logi C615, and 2 arducam usb adapters with raspi HQ cams, and since the octopi.txt file has this new entry, and is missing some entries, when it reboots it grabs the first usb camera (the Logi) as the main webcam. All cams and streams work, it just has them out of order basically. Logi first. on what should be the raspi "channel" then the second channel is broken, cause logi should be it. The 2 HQ cams work fine.
I saw that the file had changed. Thanks for reporting back, I will do some further testing.
@@ChrisRiley Ha, I don't know if you saw this, but they also, just a couple days ago, released a new Octoprint version that does away with the MJPG streamer and goes to the camera-streamer setup, and uses libcamera instead. Haven't got it up and running yet, but folks are starting to roll that out too. Love to see the progress, but at times is hard to keep up, LOL.
Hey Chris. I've been trying to get this working and have followed the instructions to the letter (as far as I can tell). I get to the point where the first camera (a usb cam) is working both in Octoprint and by the direct link in another tab. But I can't seem to get the 2nd camera working. I get the "can't reach this page and a "refused to connect" message when trying to get to the 2nd camera. Sure could use some guidance......
Can you see both the cams when you run the ls /dev command?
@@ChrisRiley Yes I can. Both show up with their dual stream addresses (0 and 1) just as you described. I can see the "primary" camera in both Octoprint and directly by IP. But can't see the other one using the IP/port address. I've confirmed that both cameras work just not simultaneously. I did this by plugging in only one at a time and by removing power from their respective USB outlets on the powered hub.
@@larryrankine8088 Sounds like a addressing problem. If you do ps -aux |grep mjpg are both ports listed?
@@ChrisRiley Doesn't look like any port is listed. This is what I get from that command
pi@octopi:~ $ sudo ps -aux |grep mjpg
[sudo] password for pi:
root 546 0.7 0.5 63380 4600 ? Sl 10:39 0:02 ./mjpg_streamer -o output_http.so -w ./www-octopi -n --listen 127.0.0.1 -i input_uvc.so -r 640x480 -d /dev/video0
pi 1175 0.0 0.0 7452 516 pts/0 S+ 10:46 0:00 grep --color=auto mjpg
When I plug both into the powered USB hub I get one of the cams. If I remove one of these and plug it directly into the pi I get that camera. I've only got the webcam2.txt setup since I've only got the two cameras.
Can we see the 2 camera videos at the same time side by side?
Only if you pull them up in a new browser with the direct URL, not in the octoprint web view.
@@ChrisRiley thanks
"My setups can be complex."
* shows us five cameras *
Complexity maintained.
🙂👍
I think this video is not applicable anymore. The Octopi.txt file has changed and this option is not there anymore...
I think I am going to have to do this one more time.
@@ChrisRiley finaly we got new tutorial, major changes was applied again :D so we have to wait :)
Over complicating? Wtf? Really? It’s amazing what people think 3D printers, software and 3rd party addons knowledge level should be. 3D printers are not plug and play… unless you like crappy prints and don’t know any better. Then buy a Bamboo labs and be done with it and stop watching TH-cam videos on 3D printing. After that you can spend your time talking to Bamboo email support to replace your broken proprietary hardware. 3D printing has come along way over the years… it’s close but not perfect. Yet. It’s still a DIY hobby with a lot of smart people making improvements that other companies are incorporating as their own. I would like to say a BIG “Thank You!” to Chris for simplifying these processes for the masses. Keep up the great work Chris! ❤❤❤
I think 3D printing is a hobby, that is making tremendous advances. While many don't like Bambu, I think you have to admit they have added a new dimension to the hobby. I have both the P1P and the X1 Carbon and they have added a new dimension to my abilities. I have had 6 Creality printers and have two Rat Rigs. All are welcome in my house.
@@woodwaker1 Bamboo is nice for those that want to just print. AMS is another story just like the MMU2 was. But, nothing on the market is plug and play and or maintenance free. Closed source and proprietary especially from China is a little ironic given they are the worst for copyright infringement. But, the guys from DJI are very smart and no company has ever come into the market with such high quality printer since Prusa. So… it is good for innovation and competition. Given bamboo labs is still new as far as being on the market. Only time will tell if quality products and customer service will last. The stories are already coming out and almost as many bad issues as good. Time will tell.
Hey, is the Carbon X1 hardware and software on the machine, Bambu studio and handy 100% functional as a standalone machine only using SD card? How about just connected to your personal network? I do not ever want to be connected to the cloud or loose functionality on hardware or software if I am not connected to the cloud. I’ve talked to them a few times and could never get a straight answer. Best I got was wiki site with the same vague answers.
Thank you! I enjoy the deep dive stuff trying to make it work. If it's easy to do, what's the fun in that?! :)
@@ChrisRiley Thanks for putting out all this great content and take the TH-cam peanut gallery comments with a grain of salt. You are doing a great job.
Hey, can you do a deep dive into Bamboo Labs. I would like first hand from someone that I trust and in the know. Is the Carbon X1 able to be used as a standalone printer, lan printer and cloud. I’ve seen others say that the bambu labs Studio software and Handy will not work completely without being connected to the cloud. Some say most things work others say studio will slice but not see the printer without the cloud. And Handy won’t work at all without the cloud. The WIKI doesn’t state early… things on the site are up for interpretation with what may be left vague for a reason? Is the firmware safe? Also is the printer itself secure? They have addressed the security issues stating it wasn’t a priority when building the printer and it is now kinda safe? Plus with security issues with IoT and sending data to the cloud and to other prying eyes? I noticed they finally put out the code for Bambu Studio. So… you get the direction I am going with this. Yes it prints good out of the box, for most. But, I want the real dirt on this printer.
Prusa XL is killing me… chop chop!
@@ChrisRiley Hi Chris. I wish you could make a tutorial video on how to incorporate the Sovol SV06 to the Sonic Pad from Creality. Regards

It doesnt work for me
What kind of error are you getting?
@@ChrisRiley Im using a rpi 3b+ with a usb camera and tried to add an endoscope. I got everything till 10:45. In my config file (the big blue text) there are only about 26 lines of code and not really much to change. (using the camera stack image).

@@ChrisRiley it's a Thumbs up :) after all these years we are still talking about MultiCams/MultiInstances on Octoprint. Keep up the Good/Hard work Chris (y)
I have 3 webcams on a powered usb hub (2 Logi Brio’s and a generic usb cam for a nozzle cam). I can see all 3 with the ls /dev/v4l/by-id command. After configuring the octopi.txt, webcam2.txt, and webcam3.txt files (the two webcam#.txt files are in the octopi.conf.d folder), only the 2 Brio’s streams show up when duplicating tabs and adding the port number. On one reboot, the nozzle cam and one of the Brio's were the 2 available cams. After rebooting again, I was back to the two Brio's. Any idea why the nozzle cam won’t show up? Could this be overtaxing the Pi? All cams are set to default resolution 640x480 @ 10fps.
I wouldn't think it was a Pi performance issue. Only thing I can think of is maybe it is trying to access the alternate stream (index 1 rather than 0) Take a look in /var/log/syslog after a reboot and see what the errors might be talking about.
