OctoPi 0.18 - Multi Printers & Cameras On 1 Pi - Chris's Basement

[@coyottedundee3642]

Clear, consistent, easy to apply.... 2023 starts in perfect conditions... Thanks a lot and best wishes for this new year...

[@ChrisRiley]

Thank you! Same to you!

[@davetpilot]

I opted to follow along with the tutorial rather than use the script. Excellent tutorial! Thank you so much. I was going to buy another Pi to run my second printer. When I went to order one, I was absolutely shocked by the current prices! Crazy. I was happy that a KZbin search yielded this gem. I am successfully running a Creality CR-6 SE and a Sovol SV04 on a Raspberry Pi 4. Both printers use Creality boards and all of the attributes are exactly the same so I had to go with the "last ditch effort" and use the devpath attribute. So far, so good. I have restarted the printers multiple times and in different orders. I've shut down everything and connected printer 1 only, printer 2 only, and both printers together. I can connect and print on both printers at the same time. To keep things organized, I bookmarked the tabs for the two instances of Octoprint (xxx.xxx.xx.xx and xxx.xxx.xx.xx:5001) and gave them the same name as the printer I want to control with that tab. I also created a printer profile for each printer on its corresponding tab.

[@ChrisRiley]

Awesome, I know man, it is crazy what they're going for. Glad you got it working.

Chris, FFS, thanks for this. And the Google Doc too??? You're the man.

[@ChrisRiley]

[@eescabar]

Awesome video! So happy you figured this out for everyone. I hated it when the old method no longer worked. This was much easier though. Maybe one day the folks at Octopi will implement a supported method.

[@ChrisRiley]

Thanks! That would be pretty sweet!

[@eescabar]

@@ChrisRiley One question Chris. I have everything set up and working except my webcam2 will show up when outside my network. I figured that was because it was using a non routable IP. So I changed it to the wan IP with 8081 as the port. Still not go. I tried a few other configurations to no avail. I should also add that I have configured my router to forward all the appropriate ports. Any ideas? I have also noticed that the time-lapse does work when using 127.0.0.1:8081 both in about outside the network. Why is that?

[@ChrisRiley]

@@eescabar It's probably something in the router, you will have to forward that port to make it accessible from the outside.

[@eescabar]

@@ChrisRiley I appreciate the reply. I ma 100% positive it is not the routerter. I am sure you doubt that., and its ok. On the old set up I had to forward the 8081 port on the octo2 and use the public ip on octo2 to configure it. On.18 I have it set up with the 192.x.x.x ip on the pi and forwarded 5001, 8080, and 8081. No go. I tried setting up webcam2 on the pi with the public IP as I did on the old version, and no go. One thing to note is that on the older version of octopi you could access the webcam streams directly in the browser outside of Octoprint. With .18 you can not wether you are in or out of the network. Its like they have been firewalled. Try it and see if you can. Id be curious. For now I went back to two separate Raspberry Pis. I know its not your job to provide support, and Im not really asking for it. I just think there is something in .18 preventing it, and if there is maybe in the future you can figure it out. Its beyond me.

[@pedroambrosio3759]

@@eescabar I'm having the same problem. Only the snapshot works using 127.0.0.1:8081.

[@bernardfocquet1258]

Thanks Chris for the video. Most people run only one printer, so it would be nice to update the tutorial to install multiple cameras for a single printer (typically usb webcam and usb endoscope) under OctoPi 0.18

[@ChrisRiley]

You're welcome, yeah, we will take another run at the multi-cam plugin sometime soon.

[@spedi6721]

So awesome! Perfectly explained as every time. Watching your tutorials makes it seem so easy 👍

Happy to hear that!

[@lucasthompson1650]

Great video as always, Chris. Just wondering, do you know if Marlin's UUID capability is (or can be) exposed over USB as a solution for a lack of serial # for, say, a basement full of Ender 3's

[@ChrisRiley]

Great question and I have tried to get it to show up over USB before with no luck. I was hoping someone would show up in the comments sometime and tell us how this works.

[@60AQI]

Great video, thumbs up! One question: I have two PlayStation 3 webcams connected to the PI (there's no serial number in neither one) and can't get them to work. Even tried inserting the devpath for both, but still no success. Any ideas?

[@ChrisRiley]

Do the cams work on the standard install. I am not sure about the PS3 cam.

[@60AQI]

@@ChrisRiley Both PS3 cameras work fine in a standard install - anyway thanks for the reply, I'll be using other webcams, since they have no issues.

Chris, great video! Just what I needed. Clear, concise, and a little hacking. Perfect. Keep up the good work.

[@ChrisRiley]

Thanks for watching, great to hear!

[@SeanTaffert]

@@ChrisRiley I just tried to follow your hack and setup 3 cams on my OctoPi with one printer....it didn't work, but I'm almost certain it's due to the lack of serial numbers on two of my cams. Lesson is, use good quality hardware or risk configuration issues.

[@WesMcGee68]

Hi Chris, I used this instruction to set up my two E5+ printers to my octopi and it works great. Only thing I can't get to show up is my first printer in the first instance of octoprint. I checked and double checked the Vendor, Product, and Serial numbers as well as the link name. printer two shows up in octoprint2 instance but printer one just connects to tty/ACM0. Cams show up fine. Printers work fine. It's just one of those things that you feel like you just HAVE to figure out LOL..... Great lesson and big help for my first time at using Octoprint. Thanks

[@ChrisRiley]

Does the first printer show up with the new name when you look at ls /dev ? If it does, the ATTRS settings are right.

[@WesMcGee68]

@@ChrisRiley Hey, I solved that problem. Under the serial connection I had added /dev/OctoEndeer1 and it should've been OctoEnder1. One extra character. I having a little issue with my octolapse on the second instance right now. And I haven't tried it on the first instance yet. Starts to print then instead of taking the initial photo the head goes to home and the bed just starts going down down down . So this morning I have a message that an update to octoprint is available. So I figured why not go ahead and update then start dealing with the octolapse issue. Well I did the update on instance one and no problem. Now, of course it only updated the first instance. So I run the update on instance 2 and it says it completes but could not restart, restart manually. So, I restart and its not updated. So, I'm going through your little walkthrough to copy and edit the files so that they are all pointing in the right directions and I'm sure that will take care of that part. And yes I know this is all just for entertainment purposes and all that, but my guy....... It is something that works pretty well when all the wheels get a little grease. I am actually able to see both printers with OctoEverywhere when I'm away. (Havent been able to control them for some reason. But I can SEE em....LOL)

[@ChrisRiley]

One character or comment makes all the difference. I'm glad you got it going. Good luck with your projects, let me know it I can help.

[@Morrlex]

Great video! Although unfortunately not 100% for me. Is it possible to assign serial numbers to printers? Followed the tutorial to a T. Unfortunately both my Ender 5 pro and Ender 5 S1 lack serial numbers and ID tags. Forced to use only USB ports and as you mentioned in the video, as soon as I turn off the PI for a few days, there’s a whole load of confusion and it can’t actually assign each printer to the instance of octoprint they should be running on.

[@ChrisRiley]

I have a new video out today that will help fix all of this.

[@Oidium45]

Do you happen to have a recommendation for two identical printers? I have two Neptune 2S. They both have the same info (name, ID, Serial, etc). I contacted Elegoo and asked if they could help me change some numbers on the main board and they declined :P

[@ChrisRiley]

This is always tough. Check this out, Paul has away to get around it. kzbin.info/www/bejne/eoLRaGBsacaAd80

[@TDHobbies]

Is there any way I can use a Pi cam on the ribbon cable and USB web cameras together? the ribon cable camera stops working after editing the files, and when I plug in the USB camera is shows it plugs in, fails to show video, but it does not show it vendor id, serial number, or nothing like that, it keeps refreshing trying to connect also. When I type in the SN manually for the webcam (that I got off the box) it will not connect that way either, I suspect it more information, or the SN is digitally different. The Pi cam doesn't show up in the log file at all, and it works before editing. Any suggestions would help, Thanks

[@ChrisRiley]

I have a secret video on how to do this. :) kzbin.info/www/bejne/l3-ceJdmfdagqs0

[@400AGLNET]

Mr. Chris, Great video / tutorial. With your instruction I was able to get the main instance up and running, using 2 different printers and 2 different camera's. My problem is no matter what port or ip I use on the 2nd instance I'm not able to open in the browser. Error says (site can't be reached). I've tried other ports and everything I can figure. Searched available ports and tried some of those as well. No Luck. So because I can't open the "2" I'm not able to connect both printers. Any thoughts or guidance would be awesome. Thanks Mel...

Hi Chris Thanks for the updated video. I'm having issues getting the cameras working. I'm using a pi-cam and a usb camera. I had this working on the last version but its not working this time round. The pi cam is on webcamd with the usb on webcamd2. webcamd is running fine but d2 starts and gives a init_videoIn failed. Any thoughts where to look. Thanks you

[@ChrisRiley]

The config has changed so much, you need to make sure you have the base config set to raspi I think, the other needs to be USB, just don't use AUTO which is the default.

[@flowgorithm]

@@ChrisRiley Thanks Chris - I'd fiddled and managed to gt it working but it was a bit flaky so i've gone down the two usb devices. Don't know about you but the new version seems to be more resource hungry on a pi3 with two instances. Restarting the server seems to take an age before it comes back up but when its up it seems to work fine. Thanks for the work you put in

Awesome work Chris, just a question. So I was able to setup 2 3D printers on to OctoPrint. I have 2 Wyze Cam v3 & would like to set them up on OctoPrint. Do you have a possible solution or video tutorial on this?

[@ChrisRiley]

I have tried to do this a couple of times with Wyze cams, it never turns out well. You have to flash them with 3rd party firmware, it's just too difficult.

[@ericsilvestri3618]

Great video. Thank you for posting this. I am running a Pi 3b, and I've successfully gotten both printers up and running on my Pi, but I cannot get my cameras to work. I have followed line by line. I don't know if it is because both of my cameras show the same serial # but I did put it in on both of them but also used the ATTRS{devpath} with the correct ports. Should I delete the serial numbers out or maybe these cheap cameras I have are not compatible?

[@ChrisRiley]

I would try to remove the serial number settings and see if that changes anything.

[@andypauloramirez9522]

Hi Chris i have 2 ender 3 and im trying to set up this octopi config, in the differntiation of the 2 3d printers (minute 12:40) when i put the commnand cat /var/log/messages putty dont bring me info about serial number (its 0 in both cases). Can i just use the serial number that is presented in the barcode that is right on the cover of the motherboard. Note: my id vendor and mi id product is the same too, just the devpath is different (1.4 and 1.3), I hope you give me a hand.

[@ChrisRiley]

Hey, no, that serial won't work. You can use the devpath parm, but it's really hard to do multiple machines like the Ender3 when they have no board serial.

[@subseauk]

Hi Chris, I am trying to add two Logitech cameras ( C270 & C920 ) to a single Prusa. Both cameras work ok with the feed appearing in octopi if I only have one plugged in. I have Multicam installed and have tried to follow yours and other KZbin and written guides on how to get them working but as yet have been unable to do this. I there any chance you could do a revised video on the easiest way as Octopi 18 says you should not need to go into the depth of file editing you had to with previous versions. I use a MacBook Pro and Terminal to SSH into the SD card on the Pi4 but I am in no way proficient at the programming language stuff so would not know where, if at all, I was going wrong. It seems as if a lot of videos take it for granted that we can all understand the very basics and leave out where files should be located etc. Please can you help?? Thanks Kev

[@ChrisRiley]

I get all my CR10's confused, but the V2 looks like it uses the stock LCD screen, so that is easier to figure out. There are a lot of great swap out boards for the CR10. The BTT Mini E3 v2.0 boards work well with Marlin at a pretty low cost.

This is great but I'd prefer to just re-install my working Octolapse on another Pi - Chris can you help? I have a fully working Octopi with Octolapse on my Raspberry Pi 4 (using with Prusa MK3S+) - I now want to use the same settings and copy them to 2 more Raspberry Pi's. The first with the same WiFi but different Octopi web address and the second with a different Wifi but the same Octopi address. I'm an amateur when it comes to the Pi so all help appreciated! A few questions: - How do I duplicate a Raspberry Pi SD card image and maintain the structure and files? I remember reading somewhere I can't just copy-paste the files Once the SD card has been duplicated: - How do I change the Wifi details? - How do I make the Octopi web address different from the original? So if 2 have the same WiFi, I can access both at the same time Is there anything else that might come up? Thanks again!

This video might help. kzbin.info/www/bejne/gWGkXqZ_iqd5nLc Basically, you will pull your working SD card, mount it on your computer and create an image, like in this video.

Chris, Awesome tutorial, worked great. Currently running 2 instances for an Ender 3 v2 and a CR10 S5 using Octoprint v1.8.4. My one question is, at 18:45 in your vid, you discuss changing the sudo commands under Server menu for "Restart Octoprint", "Restart System" and "Shutdown System". My 1st instance, these commands work fine; sudo service octoprint restart sudo shutdown -r now sudo shutdown -h now My 2nd instance, these commands fail to execute; sudo service octoprint2 restart sudo shutdown -r now sudo shutdown -h now I named my 2nd instance octoprint2 (as in the vid) and I didn't create 2 more instances. Octoprint gives me an error message saying command failed to execute. I have had to use the 1st instance to reboot as I'm not sure in Restart Octoprint is actually restarting both instances. Seems like that tho. Any insight would be great. Again, You're a F**kin badass!

Hi Chris, thanks again for the great content. Hey, do you know why the estimated time to print completion is so far off compared to what the MK3S+ screen is displaying and the code say? The MK3S+ is always almost spot on.. sometimes the print finishes slightly early. But the Octoprint estimate is way off.... and then as the print gets closer to finishing it gets more accurate. Is there something I need to calibrate in Octoprint to get it to show accurate print remaining times? Thanks for your help.

[@ChrisRiley]

Yes, Prusa is tricky! LOL They inject an M73 command at every layer to get you those accurate times. I think there are some Octoprint plugins now that can handle that same type of thing.

So all the cams are on a usb splitter hub thing like in the earlier videos. Everything works except webcam3 gets lost every now and then. I set up webcam3 by going through all the webcam2 steps and replaced 2s with 3s. Was that right? If you assume I made no errors and all my hardware is working, would some step have been different?

I'm having a hard time setting up multiple cameras for my printer. I've followed your tutorials, your old ones and your newer ones. I'm trying to get my 8mp raspberry pi camera and a logitech c920 to start with. I feel like there are some differences between what you're doing and what in front of me in putty. I also want to make a webcam with my rpi hq camera. I would just connect it to my octopi but it's heavy and makes more since to run on a tripod. The small rpi camera is perfect for mounting on the printer. My goal is to have a top down (c920), an x-axis cam, and a front camera to catch the majority of the printer.

There was also no change when unplugging the c920.

When only the Picam is plugged in I see video0, video10, video11, video12, video13, video14, video15, video 16. Yeah, I dunno why there are so many just for the Pi Cam. Also, when I plug in a second camera (endoscope) video1 AND video2 appear after an ls command. I even tried to plug in a second USB Cam (Logitech c920) making 3 total cameras total. After the third camera was plugged into the pi via a powered hub the ls command showed two more, video3 and video4. I can now tell my cameras apart (for the most part) but how do I set multiple videos into one video? Also, there are other differences as well. in the /root/bin directory. If there is a way we could communicate like if you have a discord server please share with me. I can't find any information that isn't dated and different in some way.
