Chris, many thanks for your massive contribution the 3d printing community! Your channel has became a very useful tool in my arsenal. I wanted to share this with you in case you didn't already know, concerning the "Layer Height" viewer , in which is indeed quite helpful when saving a failed print or continuing a print for whatever reason. I have personally had very clean results by doing the following: Homing the Z axis to the highest point of the salvageable object, while monitoring and documenting the Zed's coordinate reading (i.e. Z = 50.8) which of course is equivalent to 50.8 mm. Secondly, Open an instance of Octoprint. In the "Files" section, click on the name of the file that you want to continue printing, open the "GCode Viewer" tab. To the right of the viewer grid, slide the vertical (Z) and you will see your layer number along with the layer height (i.e. Layer #468 (Z= 50.8). Finally, scroll down below the viewing grid to "Layer Info" to find our layer number, height, and GCode command number, along with a new ETA. Now we can reload the model, and start printing from where we left off. Now, It has been awhile since I last used this method, but I want to say that I temporarily disabled bed leveling and auto home. it was something of that nature, but when you get to that point you will certainly know what I'm talking about! I hope this helps and if this is nothing new, Thank you again, Regardless. This would make for a great tutorial BTW ;) Peace!
Took 3 viewings to get it all, installing 1st Raspberry Pi and Octopi / Print. Thank you Chris !! You have covered some small but important details for me and clarified the use / non-use of Etcher etc. What seemed very complex to me is now quite straightforward, yet detailed enough so I can understand the what and why. Love your channel and thanks for everything you've done for your followers.
Hi, Chris. I'm new to your 3D printing world as well as 3D printing in general. I just wanted to tell you that I really appreciate your tutorial methodology. Not only do you show the necessary steps, you consistently reinforce some of the Linux basics and also point out tips not always obvious to noobies, such as myself. I'm 68 years young and my computing experience goes way, way back (Dos 1.0) but I'm new to Linux, saving the best for last. I really appreciate your help on my final journey. It's going to be a fun ride
Dude, Chris. You saved me with this video. Literally nowhere else on the internet that I can find has this info. I struggled for DAYS to get multiple instances running on the new Raspberry Pi 4, mostly referencing your old video, and had absolutely no luck. Thank you very much for posting this updated video which got everything working for me :)
Chris, as always, tons of terrific info packed into 30 minutes (+). Maybe consider disabling the announcements settings and add 'change filament' to plugins in the master image? I cant help but to customize the name, header, colors for each 'printer session' via the (Settings / APPEARANCE) controls. That is the cherry on top. Thank you, your channel is 1 of the best.
You gotta appreciate how clear and detailed he makes these videos... I’m very impressed at the level of detail you include, especially because of how easy it would be to just assume people know things beforehand or can find in Google by themselves. I highly believe this sets you apart from all the other channels! Thanks for the great tutorial!!
oh my god! it's the third time I'm writing such comment. every time I decide to upgrade or to do something to the printer, I'm opening youtube and you just made a video about it. you are the best! thanks mate!
Chris, just got my first Pi 4B setup with Octoprint. Followed your video step by step. It worked perfectly. Outstanding video as usual. Many thanks for your efforts. Making our lives so easy! Looking forward to more great content!
It’s m not sure how I wasn’t subscribed to you all this time but that just changed. Your videos seem to be the most in depth for us newbs. I can’t believe you don’t have more subscribers though.
Thanks Chris, another great video (wish I had it last week when I was setting up multi-printer instances of octoprint). In order to differentiate the different instances, I go to Settings>Appearance and change the title and colour. That way, the browser tabs take on different titles as well as the title bar in the window, and different colours are instantly recognisable for each printer.
This is really good stuff and I really appreciate the quantity and quality of the content you create! +1 for compressing the image(s). It works really well and saves the hassle of trying to dig up an old 4 GB card, tracking down an adapter, etc. My 16 GB image compressed down to the same size as the 4 GB images you shared. That said, for sharing images as you have done, using a smaller base image is nice since it makes it easier for us to use on any size card we choose.
I like how you are doing this because it is exactly what I'm doing when I'm installing a Windows system for the 1st time, installing it on a small partition then making a disc image of the fresh install, then another one with drivers, then another one with drivers and a few applications. Thank you for making this as simple as pie.
Hi Chris, I am new to 3d printing and its a bit more complicated than expected. I really appreciate your thoroughness with OctoPi/OctoPrint. Very well presented and appreciate not skipping any steps, I was able to follow through. Excellent post!!!
Thanks, amazing video, will watch fully later. I am Just starting with OctoPrint... got a 8gb pi 4. Everyone be aware; this is not supported. Someone posted an octopi build image in the github forums... I am using this, it works. But it means I am dependant on someone’s kindness to keep up with updates, cannot use images like Chris’, and who knows what problems it will cause, so, new comers, keep to a 4gb pi! 8gb requires 64bit version which is still on beta.
Great video, used some of your older videos when I was installing Octoprint originally. Definitely going to have to install that background image plugin, I have just been color coding the different instances of Octoprint. For me, one of the most useful plugins is sidebar webcam. You can setup multiple cameras with it too. I have one on each individual printer, then a single camera that covers all the printers. So you can always see the printer or all the printers.
Out of curiosity, how would you disable the extra instances? I don't need the 4th instance running in the background. Is there a command I can send to the pi to stop one or more of the instances?
Thank you Chris for your hard work and fantastis videos! I follow your videos for multiple instances of OctoPrint on my Debian 11 server. Everithing work for me. But I have issue with thumbnalis from Prusaslicer. I want one uploads folder for both instance. Thumbnalis work perfect on instance which is set up in Prusaslicer (ip, api..) but on second instance is not show thumbs. But after I press rescan button in thumbnalis settings, all thums show up. I don't know how to fix it. Do you have any idea?
Hi Crhis, o have a question, im trying to connect 4 anet a8 to the raspberry with octoprint as you do on the video, but it doesn't recognize the printers, and i don't know how to get the serial number an that info, because the step by step that you teach on the videos doesn't work too. Could yo help me please, i really need to make the upgrde. the step by step works very well on ender3
Hello Chris Great videos i am learning a lot. I have a little question. Do you need 4 raspberry pi 's for 4 printers with what you explain or just one for the 4 printesr? If you need only one , how do you connect the printers on one raspberry? Thanks for your respone.
Thanks so much Chris, One question for you if i can, is there a way to set the addresses to each printer, i noticed that one i power down the address mixes up for that printer... eg i have 2x cr6se the address for the 1st is 192.xx.xx.62 and the 2nd 192.xx.xx.62:5001 after power down the address for the 1st printer becomes :5001 and 2nd xx.62. makes it very hard when trying to work out what printer i am sending the gcode to. thanks in advance :)
great info! one question.. .why not mount 'boot' partition as read/write from your putty session and re-add that os expansion flag back into cmdline file?
Thanks, Chris. I find your videos very informative. I've just installed OctoPi with the intent to run two printers from it, but the octoprint.service file isn't there. The script in /etc/init.d/octoprint is there, but that's generated from somewhere. Is this because I grabbed the stable 0.17 release instead of the 0.18rc?
Fantastic video. I'm setting up three printers in the basement and would really like to use the multi Octopi install but it appears OctoPrint 1.5.3 Python 3.7.3 OctoPi 0.18.0 has once again changed how cameras are handled. A follow-up video on how to install one camera for each instance using the latest versions would be very much appreciated. Keep up the great work.
Great video as usual. But I'm having trouble upgrading from 1.4.0 to 1.6.1 Octoprint, it just errors each time. I have used a terminal to "sudo apt update/upgrade" the Rpi. but nothing i try will upgrade Octoprint. Any idea what's wrong and how to upgrade OctoPi? Or do I have to re flash an image and start again? thanks
Say... Do you have any information available to get an i3 MK3S with an MMU2S working on OctoPi? Gave the latter a try today as an alternative to the Toshiba Flash Air-04 SD Card ( thanks for that video! ) I've been using so far, and I'm already not impressed with how things are running in terms of getting things started as the Printer keeps nagging about the Filament 😐
I have no update on it, but I would very much like Prusa to get this sorted out. You might check on the status over on there github. I am sure there are tons of posts on it.
@@ChrisRiley Found the issue... I "forgot" to config the Printer to have more than one Extruder - But in my defence, I saw that setting but since it technically doesn't have more than one Extruder, I didn't bother with it at first which is why I didn't activate that setting so I never saw the option to select a _Shared Nozzle_ option - So yea... I was now able to send it a single colour Print and it actually selected the proper one instead of complaining.
Question for ya. I have a Raspberry Pi 3 B+ and when I try to connect to it thru Wi-Fi I can't. When I boot up to it I get a green light blinking for a few seconds then its not there anymore. I try to connect via web browser and it tells me that something about network domain. What am I doing wrong? I followed your directions the right way, I don't know what's wrong. Any suggestions would be greatly appreciated.
Hi Chris, thanks for another great video! Can you please help me with my Octoprint problem? I have it running absolutely fine but for some reason all of my prints sent directly via the Cura plugin are so under-extruded as to be only fit for the trash bin! You can actually see through them in places. What am I missing here? Any advice would be greatly appreciated, keep up the excellent work ✌
@@ChrisRiley I am still in the process of trying that out, I had a bit of a minor problem in that I accidentally severed one of the hot end thermistor wires. I have repaired it now so I may try printing from the SD tomorrow. I will keep you posted, thanks.
A small note" if backing up your tweaked Raspbian system, have a look at pishrink and similar. These take your inflated image and deflate it (like from 16 GB to some 5 GB or whatever space it really needs). I have a script somewhere, that combines pishrink with wput and/or dd for an easy backup in one. But well, if yo have a 4 GB card around, suit yourself.
Hey Chris....ever heard of MK3 motherboard going bad? The heater cartridge, 2 diff new ones, temp keep fluctuating wildly at times.....any ideas besides a bad board? Thanks
I am working on getting this going and thank you for a very informative video! If I have no intention of a farm, do I really need to worry about the 4gb card? Also I see in your other video that you thought Octoprint anywhere/everywhere was great. Should I use that instead of port forwarding? Thanks!
Chris, can you recommend good budget IDEX printer? Any opinion on the tenlog tl-d3? Just for hobby use, I want to avoid anything proprietary. .Thanks for the great content, I got octoprint running last night!!
I don't know of many actually. The only budget one I know about was this one, haven't heard great things. www.amazon.com/Artist-D-Extruder-Printers-300x300x340mm-Pre-Assemble/dp/B08YN8QQ21/ref=asc_df_B08YN8QQ21/?tag=hyprod-20&linkCode=df0&hvadid=509686536470&hvpos=&hvnetw=g&hvrand=13700612628043708239&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9023193&hvtargid=pla-1268918102354&psc=1
For the multi instance install, wouldn't it be a bit faster to sudo su to skip all those sudo commands, and copy instance 2 to instance 3 and 4 after editing instance 2?
Hey Chris. While I have watched all your other Octoprint videos, still enjoyed this as well. Have you looked into Docker at all? Would be curious to hear your thoughts on it. I've got it working on a Raspberry Pi 4 and had 3 printers running off it until recently where I moved one down to my basement. Only catch is having to restart the docker instance after powering on all the printers. Minor inconvenience really. I found that when having multiple printers on one Pi that the plugins would overlap and I ran into a couple instances of one print stopping midprint because of it. Haven't had that happen since using Docker. Still too early to tell though, but am liking it so far. One other plugin I like is Themeify. Can have it with a dark background (Discorded theme) and also expand Octoprint so it takes up the whole screen if you like. Just click the checkbox to "Enable customization", then add the following entries under Advanced options > Custom style. This is how I have mine set, but adjust to whatever your preference is. .span8 - width - 1000px .container - width - 1400px Also TP-Link Smartplug is another good plugin so I can turn the printers on and off remotely.
Nice, the dark theme sounds cool. I have tried docker and it seems to work well. I don't show it on the videos because I think the docker install is a bit much for some folks and I can script this process pretty easily into a one liner. It might be something I still try to do a video on in the future.
When using your image, my webcam (PS3 Webcam) does not work... I can see it is connected with ls /dev | grep "video*" ls -l /dev/v4l/by-id But the stream does not come up... How can i use the camera? (is it possible to use the same camera for all instances?) thanks!
sir, i heard that we can connect raps pi to printer using gpio, is it really fix the buffering issue when connecting via usb? and can we use it for multiple printers?
Yes, you can connect up using GPIO, but it's not going to give you any improved performance over USB. It would be really hard to use on multiple printers.
Hello Chris; thanks for your video, is a good explanation for noobs like me, hahaha, However, I have a quick question for you Sir, I tried to install 2 printers with 2 cameras (one for each), I checked out your video of how to do that in your channel, I did exactly the same procedure and actually the camera services 1 & 2 runs with no problem, I can get the image in the Octoprint Service, but just only from the main camera of the main octoprint, if I tried to get the image from the second octoprint I have " webcam stream not loaded" however if I unplug the main camera and reset the raspberry-pi the streaming service goes directly to the second camera, but never goes to the second octoprint as I configured, have you seen this issue before?
Chris, the longer pins were ordered from the link you posted and will take a few weeks to receive according to the delivery status. That is ok. Would like to make use of the Wireless loading of files while I wait on pins to arrive, could I use a USB cable connected between the Zero and Prusa printer? What would be different in the setup if the Zero USB connection was plugged into the USB port on the Prusa printer? Does the Rambo board provide power via the connection to the Zero? Thank you for incredible job you do with your videos.
@@ChrisRiley on Monday decided I would plug the power into the one USB port on the Zero and the other USB would be the connection to the USB port on the Printer. It worked. I created on SD card for piggyback setup and one for USB cable only setup. What I find absolutely maddening is they brought +5v, GND, Tx, and Rc out the back of the Rambo board but left out the power pin and gnd on the connection ontop of the case of the printer.
What do you suggest to upgrade to OctoPi 0.18.0 RC 2? If I make a backup in OctoPi, with restore I'll found all the settings of the HyperPixel display and so on?
Can you connect to your 3D printer via Octoprint if you are not connected via your WIFI meaning via cellular network? Mine disconnects if I am not at home
I did everything for OCTOPRINT on my "rpi3 B+ " but can not able to connect with my wifi router.I used angry IP scanner but not found any devices ( rpi or OCTOPRINT ).Can you please give me any suggestions what can I do ? ( For testing purpose I installed raspbianOS .It was perfectly ok or able to connected with Wi-Fi).
@@ChrisRiley I am using "Raspberry Pi Imager" and using ctrl+shift+X for password.there is no way to mistake.can you tell me if I connect it with a monitor can I check the wifi router status ?
I used Chris's multi image system image and I can connect to octoimg.local but not to the other 4 like octoimg.local:5001. any help would be appreciated
Great video! One question though, running multiple instances of Octoprint is great I like it, but I've read online that sometimes the USB connection can sometimes cause issues when it's communicating to and from the printer and even cause prints to come out funny. I was reading where someone used the GPIO pins TX(14) and RX(15), like in a simple RS-232 connection actually made their prints better and didn't have any comms issues after that. Have you ever tried this before? I would think using the GPIO pins you could only do this on one PI per printer and the motherboard has to have a UART connection to communicate to. Great video by the way! Let me know what you think.
Great video but I’m having issues. I set my ssid & password and as from uk I didn’t need to change that. Saved it when I plugged into raspberry the green LED flash’s a bit then doesn’t. Not sure what’s gone wrong
It almost has to be something with the SSid or password, or a comment didn't get removed or did get removed on accident. You can plug it in to a wired network connection to login and see what's wrong. The wired connection is always available.
When is that camera video popping? Also, btw, I dont know if its because of a change or something, but I added host and port to the config.yaml under the servers section because the -- help no longer listed the host and port options so it seems like it has changed. I did try the method here, but it resulted in failure to start the services. Edit: Also of note, I did have to also remove the port and host options from the services --- Another Edit: So I have followed the official guide and am modifying the webcamDaemon to run both my c270 and Raspberry pi cam on different ports (I have 2 printers so Im using 5000 for printer 0, 5001 for printer 2, 5100 for printer 0 camera and 5101 for printer 2 camera. I just duplicated the webcamDaemon file and set one to usb and one to raspi and added a -p [port number] to get them on the right ports I did also change these settings: camera_usb_options="-r 1280x720 -f 30 -l blink" camera_raspi_options="-fps 30 -x 1920 -y 1080" OK last edit I promise..... So I think a lot of the difference Ive seen is I manually installed octoprint on a fresh lite Raspberry OS
So I'm attempting to add multiple instances. Whether I try using the quick way on your doc or by going through line by line, it gives me the following message: update-rc.d: error: cannot find a LSB script for octoprint2 and it does the same for 3 and 4. any help?
As someone who had a fileserver running on a 32gig Micro SD that was only half partitioned burn out its boot device: Can one install Octoprint for the Raspi 4B on an SSD for reliability? Not bc I want to leave 116gig unpartitioned but bc the controller actually can stand the test of time. Thx in advance!
@@ChrisRiley Yeah, you have to update the firmware and change the bootorder to USB first and there are videos where ppl boot RaspiOS but I haven't seen any other operating system being bootet from USB^^
Hey Chris, thanks for doing this video. I used your script file in the docs, but it seems my USB rules file that was created isn't writeable....any ideas how I can put that right?
Chris Thanks for another great technical video! You have made me wonder about the advantages of switching from my Pi 3 to the Pi 4. Are there advantages that make it worthwhile? If so, is it best to get the larger on board memory size? David
@@ChrisRiley, all - as I said I got it to work, based on a beta image someone compiled on 64 bits and posted on the forums. I have not tried many plugins and only tried it with OctoDash, I don't know what will work and what will not on it, I need further time (after holidays period) to test it. See it as a bit of risk now as it is 'unofficial'. Now I notice there is a 64 bit release candidate on the OctoPi site, that might support the 8Gb verstion natively. I think it's just a matter of time for them to support it.
@@ChrisRiley Thanks, Chris. It turned out to be an unreadable octoprint image on the sd card. After I sorted that out, it was a walk in the park. After getting a Pi, I'm now watching all your videos about them I didn't watch before. Great stuff, Chris!
With octoprint and timelapse, it won't matter much, even the pi3 is overkill for most of this. The only time to be concerned is with high res video and even then that is more about processing power.
Chris, a lot of information and well presented. How do you control 4 printers with one Pi via USB cables? Do you use a hub - just curious how you cable them. I have a Pi for leach printer and have them spread out in my basement, trying to figure out how the wiring would work. Thanks for the hard work
Lots of good tips here even for someone already familiar with Octoprint, so thanks for the vid. Why not compress those disk images so they don't take so much space on your hard drive?
Thank u so much for this! Your videos are super helpful and informative. My AMAZING wife just got me a pi 4 8gb and I am attempting to get it running both my Tronxy XY 2 Pro and my Son's Ender 3 Pro. I was able to get the tronxy runnung great but am attempting to set up both printers and 2 webcams with your video. However I am unable to login to the other IPs that are created?. I know that this Pi has to use the 64 bit version but I assumed everything else would work the same? Also I only need 2 instances how could I modify your script from the doc to only create one duplicate? Thank you for your time and keep the great videos coming!
You mean the IP with the port on it, like 192.168.1.x:5001 you can't login or you can't reach it. The easiest way to limit it to 2 would be to just disable the other 2. sudo systemctl disable octoprint3 sudo systemctl disable octoprint4
@@ChrisRiley When I open the :5001 IP it asks me for my login information and when I try to log in it says its invalid. For now I have loaded your multi-instance image and have that working with 2 printers and one of the webcams. Thank you for the tip on how to disable the other instances I don't need. I am going to try to do that and get the other webcam working when I have some time. I really appreciate you taking the time to make these videos and answer questions. It is a huge help to the community. I guess Ill just wait until you have a video specifically for the 64 bit image setup so I don't mess it up 😆
You are a god send, thank you. If I used a 32gb when I first got all my setting done, am I stuck using only 32gb SD cards and having a 32gb image back up on my regular computer?
The easiest way is to use pishrink ostechnix.com/pishrink-make-raspberry-pi-images-smaller/ on your current image file, you can zip it to make it small for storing.
On port numbers. I ususally like to match the port to the instance number, so for instance2 I would use port 5002, instance port 5003, etc. It helps me remember without having to think too much. :)
In PrusaSlicer 2.3 on the tab "Printer Settings" in the section "Firmware" there is a setting "G-code thumbnails". There you can put e.g. "16x16, 220x124".
@@ChrisRiley If you used an entry in the printer .ini file before to create the thumbnails and keep the field in the gui empty, because you don't know it's there, this empty field overwrites the entry in the .ini file and there will be no thumbnail.

Hello Chris, I am 7 years old and currently getting into 3D Printing. I actually have a 3D Printer, because I got one for free from the school. I've fixed almost everything on it, however it was missing it's old micro SD card, and now I have no clue what firmware to install. It's a geetech prusa i3 pro B clone, I sadly d not know the name of the board as it was not printed on the board or printer, but it's a red board that's slightly smaller than those you'd see on official machines, if that helps. Would you happen to know what firmware to use, and if not, would you happen to be able to point me in the direction to finding the right firmware? For instance something like a website that explains what the firmware does for the machine, and how to stay safe while working with Gcode. I'm sorry for asking for so much but I figure I'd give it a shot. BTW the printer powers on, and almost works, It just says "card insterted" instead of "i3 pro B ready" so I figure I need to put the right firmware on the sd
actually believe it or not i found a video right after leaving this comment that pretty much solved my issue, ruclips.net/video/cXOIoT8-zQ0/видео.html&ab_channel=Zachary3DPrints this dude has my exact same printer and he's updating his firmware

I’m very impressed at the level of detail you include, especially because of how easy it would be to just assume people know things beforehand or can find in Google by themselves. I highly believe this sets you apart from all the other channels! Thanks for the great tutorial!!
Thanks!
oh my god! it's the third time I'm writing such comment. every time I decide to upgrade or to do something to the printer, I'm opening youtube and you just made a video about it. you are the best! thanks mate!
Thanks!
Chris, just got my first Pi 4B setup with Octoprint. Followed your video step by step. It worked perfectly. Outstanding video as usual. Many thanks for your efforts. Making our lives so easy! Looking forward to more great content!
Awesome! Great to hear it's working for you.
It’s m not sure how I wasn’t subscribed to you all this time but that just changed. Your videos seem to be the most in depth for us newbs. I can’t believe you don’t have more subscribers though.
Thanks for the sub!
Thanks Chris new to the game you time to teach noobs is greatly appreciated!
Glad to help! Thanks for watching
Thanks Chris, another great video (wish I had it last week when I was setting up multi-printer instances of octoprint).
In order to differentiate the different instances, I go to Settings>Appearance and change the title and colour. That way, the browser tabs take on different titles as well as the title bar in the window, and different colours are instantly recognisable for each printer.
Thanks! Yes, I like to do that as well, anything to keep me from canceling the wrong print. LOL
This is really good stuff and I really appreciate the quantity and quality of the content you create!
+1 for compressing the image(s). It works really well and saves the hassle of trying to dig up an old 4 GB card, tracking down an adapter, etc. My 16 GB image compressed down to the same size as the 4 GB images you shared. That said, for sharing images as you have done, using a smaller base image is nice since it makes it easier for us to use on any size card we choose.
Glad you enjoy it! I should have thought of this ahead of time. Compression would have been the fix.
I like how you are doing this because it is exactly what I'm doing when I'm installing a Windows system for the 1st time, installing it on a small partition then making a disc image of the fresh install, then another one with drivers, then another one with drivers and a few applications.
Thank you for making this as simple as pie.
Thank you
same
Always great content! For as many times as I have had to re-install Octopi, I never thought of creating a master image. Nicely done as always.
Glad to help! Thanks
Hi Chris, I am new to 3d printing and its a bit more complicated than expected. I really appreciate your thoroughness with OctoPi/OctoPrint. Very well presented and appreciate not skipping any steps, I was able to follow through. Excellent post!!!
Great to hear!
Great video as always, you could be a good school teacher because you explain the subject in the right way for us to understand.
Wow, thank you!
I can't tell you how many things I learned from watching this video (most of many you probably didn't even think about, haha). THANK YOU!
Glad I could help! Thanks
Fantastic Chris. Thanks so much, again. Always come back to watch your tuts on how to do multi instances.
Thanks, I'm happy to help
Very useful. I love the new plugins. Building a baseline image is certainly a time saver. (may just be my next project.)
Good luck! Thanks for watching
good stuff, we really appreciate the work you put into these tutorials
Glad you like them! Thanks
Second this!! Best videos for learning about octopi and other topics, VERY well put together Chris, feel proud.
Brilliant tutorial, makes it seem a lot less complicated for a total beginner in 3d printing and Octoprint.
Glad it was helpful!
Thanks, amazing video, will watch fully later. I am Just starting with OctoPrint... got a 8gb pi 4. Everyone be aware; this is not supported. Someone posted an octopi build image in the github forums... I am using this, it works. But it means I am dependant on someone’s kindness to keep up with updates, cannot use images like Chris’, and who knows what problems it will cause, so, new comers, keep to a 4gb pi! 8gb requires 64bit version which is still on beta.
Thanks again for this info Juan.
I am in the same boat but Im sure someone smarter than me at this stuff (Chris) is gonna save the day 😆.
Thanks to you Chris I looked at my router from my provider and found how to assign the IP addresses as static. :)
Fantastic! Thanks
Great video, used some of your older videos when I was installing Octoprint originally. Definitely going to have to install that background image plugin, I have just been color coding the different instances of Octoprint.
For me, one of the most useful plugins is sidebar webcam. You can setup multiple cameras with it too. I have one on each individual printer, then a single camera that covers all the printers. So you can always see the printer or all the printers.
I like the webcam too. Thanks
@@ChrisRiley Merry Christmas!
Chris, great video as usual! One trick when you create images or backups, you can shrink to minimal size if you use Pi-Power-Tools.
Great tip! Thanks
Very interesting. Thanks for showing!
Thanks for watching!
Out of curiosity, how would you disable the extra instances? I don't need the 4th instance running in the background. Is there a command I can send to the pi to stop one or more of the instances?
You can disable them so they don't start. sudo systemctl disable octoprint3
@@ChrisRiley awesome! Thanks for responding, I appreciate it!
Thanks Chris. Will check it out. Have a nice christmas
You too, thanks for watching

Same to you! Thanks
Thank you Chris for your hard work and fantastis videos! I follow your videos for multiple instances of OctoPrint on my Debian 11 server. Everithing work for me. But I have issue with thumbnalis from Prusaslicer. I want one uploads folder for both instance. Thumbnalis work perfect on instance which is set up in Prusaslicer (ip, api..) but on second instance is not show thumbs. But after I press rescan button in thumbnalis settings, all thums show up. I don't know how to fix it. Do you have any idea?
That's a great question and I could never figure out why that happens. I will look at it further to see if I can get it working.
Hi Crhis, o have a question, im trying to connect 4 anet a8 to the raspberry with octoprint as you do on the video, but it doesn't recognize the printers, and i don't know how to get the serial number an that info, because the step by step that you teach on the videos doesn't work too. Could yo help me please, i really need to make the upgrde. the step by step works very well on ender3
I'm not sure how this would work, you probably have to use devpath..
Hello Chris
Great videos i am learning a lot.
I have a little question.
Do you need 4 raspberry pi 's for 4 printers with what you explain or just one for the 4 printesr?
If you need only one , how do you connect the printers on one raspberry?
Thanks for your respone.
You can run 4 printers on one pi, but you can't use any camera, you would use up all 4 USB ports for the printers.
Thank you Chris
Thanks so much Chris, One question for you if i can, is there a way to set the addresses to each printer, i noticed that one i power down the address mixes up for that printer... eg i have 2x cr6se the address for the 1st is 192.xx.xx.62 and the 2nd 192.xx.xx.62:5001 after power down the address for the 1st printer becomes :5001 and 2nd xx.62. makes it very hard when trying to work out what printer i am sending the gcode to. thanks in advance :)
If your boards have the same ATTRS and no serials about your only option is the devpath. I will explain that in tomorrows video.
@@ChrisRiley Awesome Thank You
Best videos for octoprint software! Thanks for all your work on this, you've saved me more times than I can count :D
Glad to help! Thanks for watching
great info!
one question.. .why not mount 'boot' partition as read/write from your putty session and re-add that os expansion flag back into cmdline file?
Thanks! No reason, that would work fine as well.
Thanks Chris. I have used this for a while thanks to you.
Great to hear! Thank you
i have 2 generic usb web cams and i do not get a serial number for them. how would i add these 2 cameras
You would have to use ATTRS{devpath} and the USB numbers. They 1.2 and 1.4 they are in the log.
Thanks, Chris. I find your videos very informative. I've just installed OctoPi with the intent to run two printers from it, but the octoprint.service file isn't there. The script in /etc/init.d/octoprint is there, but that's generated from somewhere. Is this because I grabbed the stable 0.17 release instead of the 0.18rc?
Yes, it's different in 0.18, try this. ruclips.net/video/dLDRzggyhKs/видео.html
Do you have a guide for Octoprint working with the Big Tree Tech Filament guide.
Filament guide, not sure what that one is, do you have a link?
Fantastic video. I'm setting up three printers in the basement and would really like to use the multi Octopi install but it appears OctoPrint 1.5.3 Python 3.7.3 OctoPi 0.18.0 has once again changed how cameras are handled. A follow-up video on how to install one camera for each instance using the latest versions would be very much appreciated. Keep up the great work.
Video on this out next week.
@@ChrisRiley Just finished watching the video. Thanks so much
Great video as usual. But I'm having trouble upgrading from 1.4.0 to 1.6.1 Octoprint, it just errors each time. I have used a terminal to "sudo apt update/upgrade" the Rpi. but nothing i try will upgrade Octoprint. Any idea what's wrong and how to upgrade OctoPi? Or do I have to re flash an image and start again? thanks
Update: had to update Python from 2.7 to 3 first.
keep up the great videos.
Ah, nice, glad you found a fix.
Nothing like a little PI for xmas
mmmmmmm
Say... Do you have any information available to get an i3 MK3S with an MMU2S working on OctoPi?
Gave the latter a try today as an alternative to the Toshiba Flash Air-04 SD Card ( thanks for that video! ) I've been using so far, and I'm already not impressed with how things are running in terms of getting things started as the Printer keeps nagging about the Filament 😐
I have no update on it, but I would very much like Prusa to get this sorted out. You might check on the status over on there github. I am sure there are tons of posts on it.
@@ChrisRiley Found the issue... I "forgot" to config the Printer to have more than one Extruder - But in my defence, I saw that setting but since it technically doesn't have more than one Extruder, I didn't bother with it at first which is why I didn't activate that setting so I never saw the option to select a _Shared Nozzle_ option - So yea... I was now able to send it a single colour Print and it actually selected the proper one instead of complaining.
Question for ya. I have a Raspberry Pi 3 B+ and when I try to connect to it thru Wi-Fi I can't. When I boot up to it I get a green light blinking for a few seconds then its not there anymore. I try to connect via web browser and it tells me that something about network domain. What am I doing wrong? I followed your directions the right way, I don't know what's wrong. Any suggestions would be greatly appreciated.
That usually means it can't get into the network. It's almost always something wrong in the WPA supplicant file.
Hi Chris, thanks for another great video! Can you please help me with my Octoprint problem? I have it running absolutely fine but for some reason all of my prints sent directly via the Cura plugin are so under-extruded as to be only fit for the trash bin! You can actually see through them in places. What am I missing here? Any advice would be greatly appreciated, keep up the excellent work ✌
Hey Fred, do those Cura prints work from the SD card okay?
@@ChrisRiley I am still in the process of trying that out, I had a bit of a minor problem in that I accidentally severed one of the hot end thermistor wires. I have repaired it now so I may try printing from the SD tomorrow. I will keep you posted, thanks.
A small note" if backing up your tweaked Raspbian system, have a look at pishrink and similar. These take your inflated image and deflate it (like from 16 GB to some 5 GB or whatever space it really needs). I have a script somewhere, that combines pishrink with wput and/or dd for an easy backup in one. But well, if yo have a 4 GB card around, suit yourself.
Thanks for the tip, a lot of others have suggested this. I need to try it.
@@ChrisRiley It is a linuxey thingy. :o) But I am sure there will be some port for windows too.
Hey Chris....ever heard of MK3 motherboard going bad? The heater cartridge, 2 diff new ones, temp keep fluctuating wildly at times.....any ideas besides a bad board? Thanks
I haven't but it can happen for sure, if you are out of warranty contact Ultimachine, they can probably help.
Great video. Can I follow the same steps from your Linux multi instances video to add multiple web cams on a raspberry pi multi instances install?
You can, but somethings have changed with the newer versions. You should be able to put the two videos together and make it work.
I am working on getting this going and thank you for a very informative video! If I have no intention of a farm, do I really need to worry about the 4gb card? Also I see in your other video that you thought Octoprint anywhere/everywhere was great. Should I use that instead of port forwarding? Thanks!
No, you don't need to worry about the 4gb card unless you want to save the image off. Yes, octoprint anywhere is a lot safer than port forwarding.
@@ChrisRiley thanks Chris! Your videos are great and very informative!

Great stuff! Thanks Chris 🙏
Glad you liked it! Thanks
Verry Good !!! do you have a solution to get Webcams for any Instanze of Octoprint ?
This one should work ruclips.net/video/FIPbiImixZM/видео.html
For the multi instance install, wouldn't it be a bit faster to sudo su to skip all those sudo commands, and copy instance 2 to instance 3 and 4 after editing instance 2?
Sure, you can do it whichever way works for you. I use root in the doc so you can do this all at once.
Hey Chris. While I have watched all your other Octoprint videos, still enjoyed this as well. Have you looked into Docker at all? Would be curious to hear your thoughts on it. I've got it working on a Raspberry Pi 4 and had 3 printers running off it until recently where I moved one down to my basement. Only catch is having to restart the docker instance after powering on all the printers. Minor inconvenience really. I found that when having multiple printers on one Pi that the plugins would overlap and I ran into a couple instances of one print stopping midprint because of it. Haven't had that happen since using Docker. Still too early to tell though, but am liking it so far.
One other plugin I like is Themeify. Can have it with a dark background (Discorded theme) and also expand Octoprint so it takes up the whole screen if you like.
Just click the checkbox to "Enable customization", then add the following entries under Advanced options > Custom style. This is how I have mine set, but adjust to whatever your preference is.
.span8 - width - 1000px
.container - width - 1400px
Also TP-Link Smartplug is another good plugin so I can turn the printers on and off remotely.
Nice, the dark theme sounds cool. I have tried docker and it seems to work well. I don't show it on the videos because I think the docker install is a bit much for some folks and I can script this process pretty easily into a one liner. It might be something I still try to do a video on in the future.
When using your image, my webcam (PS3 Webcam) does not work... I can see it is connected with
ls /dev | grep "video*"
ls -l /dev/v4l/by-id
But the stream does not come up... How can i use the camera? (is it possible to use the same camera for all instances?)
thanks!
I am not sure how the cams work on 0.18, I will be doing a video on this soon.
Great video. I would like to add two security cameras for around my shop. How would I do that?
If the camera have an IP interface all you need to do is out that IP in octoprint settings and it will pull it in.
@@ChrisRiley That is what I was thinking, thanks for confirming it. Thanks for a quick reply
sir, i heard that we can connect raps pi to printer using gpio, is it really fix the buffering issue when connecting via usb? and can we use it for multiple printers?
Yes, you can connect up using GPIO, but it's not going to give you any improved performance over USB. It would be really hard to use on multiple printers.
@@ChrisRiley thank you.
Thank you for the incredibly detailed tutorial. I really appreciate the effort taken to put this together. Cheers 👍😎🇦🇺
Glad it was helpful!
Dude, you are an awesome youtuber Thanks for your time and effort, we appreciate it!.
Wow, thank you!
Hello Chris; thanks for your video, is a good explanation for noobs like me, hahaha, However, I have a quick question for you Sir, I tried to install 2 printers with 2 cameras (one for each), I checked out your video of how to do that in your channel, I did exactly the same procedure and actually the camera services 1 & 2 runs with no problem, I can get the image in the Octoprint Service, but just only from the main camera of the main octoprint, if I tried to get the image from the second octoprint I have " webcam stream not loaded" however if I unplug the main camera and reset the raspberry-pi the streaming service goes directly to the second camera, but never goes to the second octoprint as I configured, have you seen this issue before?
Yes, this config has changed a bit. I have a video coming out next week that will explain this all.
Chris, the longer pins were ordered from the link you posted and will take a few weeks to receive according to the delivery status. That is ok.
Would like to make use of the Wireless loading of files while I wait on pins to arrive, could I use a USB cable connected between the Zero and Prusa printer?
What would be different in the setup if the Zero USB connection was plugged into the USB port on the Prusa printer? Does the Rambo board provide power via the connection to the Zero?
Thank you for incredible job you do with your videos.
You can use USB but you'll need a power supply for the Pi. Don't make the Linux file changes.
@@ChrisRiley on Monday decided I would plug the power into the one USB port on the Zero and the other USB would be the connection to the USB port on the Printer. It worked. I created on SD card for piggyback setup and one for USB cable only setup.
What I find absolutely maddening is they brought +5v, GND, Tx, and Rc out the back of the Rambo board but left out the power pin and gnd on the connection ontop of the case of the printer.
What do you suggest to upgrade to OctoPi 0.18.0 RC 2? If I make a backup in OctoPi, with restore I'll found all the settings of the HyperPixel display and so on?
I don't know that your back will be able to reload on to the new 0.18, I would use a new SD card and try so you don't lose your install.
Can you connect to your 3D printer via Octoprint if you are not connected via your WIFI meaning via cellular network? Mine disconnects if I am not at home
You can, but you would need to open a firewall port or use a VPN. Check your octoprint anywhere.
@@ChrisRiley thanks so much, Chris

The only thing I can think of is a firewall issue. Make sure the services are running. sudo service status octoprint2
Great video! One question though, running multiple instances of Octoprint is great I like it, but I've read online that sometimes the USB connection can sometimes cause issues when it's communicating to and from the printer and even cause prints to come out funny. I was reading where someone used the GPIO pins TX(14) and RX(15), like in a simple RS-232 connection actually made their prints better and didn't have any comms issues after that. Have you ever tried this before? I would think using the GPIO pins you could only do this on one PI per printer and the motherboard has to have a UART connection to communicate to. Great video by the way! Let me know what you think.
I have tried that and it does work well. You are right though, it would be difficult to run multiples that way.
do I need to do the multi instance install if I only have one printer?
No, only if you have more than one.
@@ChrisRiley yeah I figured it out, thanks!
SUPER useful, and thanks especially for the prefabbed images!

Great video but I’m having issues. I set my ssid & password and as from uk I didn’t need to change that. Saved it when I plugged into raspberry the green LED flash’s a bit then doesn’t. Not sure what’s gone wrong
It almost has to be something with the SSid or password, or a comment didn't get removed or did get removed on accident. You can plug it in to a wired network connection to login and see what's wrong. The wired connection is always available.
When is that camera video popping?
Also, btw, I dont know if its because of a change or something, but I added host and port to the config.yaml under the servers section because the -- help no longer listed the host and port options so it seems like it has changed.
I did try the method here, but it resulted in failure to start the services.
Edit: Also of note, I did have to also remove the port and host options from the services

Another Edit:
So I have followed the official guide and am modifying the webcamDaemon to run both my c270 and Raspberry pi cam on different ports (I have 2 printers so Im using 5000 for printer 0, 5001 for printer 2, 5100 for printer 0 camera and 5101 for printer 2 camera.
I just duplicated the webcamDaemon file and set one to usb and one to raspi and added a -p [port number] to get them on the right ports
I did also change these settings:
camera_usb_options="-r 1280x720 -f 30 -l blink"
camera_raspi_options="-fps 30 -x 1920 -y 1080"
OK last edit I promise.....
So I think a lot of the difference Ive seen is I manually installed octoprint on a fresh lite Raspberry OS
Yes, things the octopi install will do will make it look different, but basically that is how we will need to do camera going forward.
What do you do if you need the image in 6 months time, and it is completely out of date? Sorry if this is a noob question.😔
I rebuild mine every year or so with all the updates built in.

Are there advantages that make it worthwhile? If so, is it best to get the larger on board memory size?

Watch out 8gb pi 4 not supported. Someone posted a compiled octopi image for this but not part of official releases, Chris’ image would not work, etc
Not yet,
Hopefully soon!
Thanks Jaun
Thanks Juan, I had heard there were some pi4's that weren't working yet. As of right now the pi3 works just as well as pi4.
@@ChrisRiley, all - as I said I got it to work, based on a beta image someone compiled on 64 bits and posted on the forums. I have not tried many plugins and only tried it with OctoDash, I don't know what will work and what will not on it, I need further time (after holidays period) to test it. See it as a bit of risk now as it is 'unofficial'. Now I notice there is a 64 bit release candidate on the OctoPi site, that might support the 8Gb verstion natively. I think it's just a matter of time for them to support it.
I can't set up my raspberry pi 4. I got as far as the red light coming on and I'm lost on the rest. Help!
It's probably a network issue. If you can't get the wifi to work, try plugging in a network cable.
@@ChrisRiley Thanks, Chris. It turned out to be an unreadable octoprint image on the sd card. After I sorted that out, it was a walk in the park. After getting a Pi, I'm now watching all your videos about them I didn't watch before. Great stuff, Chris!
On your view what RAM option on the PI4 should you use 2GB or 4GB, I want to do time-lapse so would a 32GB SD card be good or should I go bigger?
With octoprint and timelapse, it won't matter much, even the pi3 is overkill for most of this. The only time to be concerned is with high res video and even then that is more about processing power.
Chris, a lot of information and well presented. How do you control 4 printers with one Pi via USB cables? Do you use a hub - just curious how you cable them. I have a Pi for leach printer and have them spread out in my basement, trying to figure out how the wiring would work. Thanks for the hard work
Hey Dave, I use all 4 ports on the pi, I just don't run any cams. Running multiple cams is a real pain.

You mean the IP with the port on it, like 192.168.1.x:5001 you can't login or you can't reach it. The easiest way to limit it to 2 would be to just disable the other 2. sudo systemctl disable octoprint3 sudo systemctl disable octoprint4

I am going to try to do that and get the other webcam working when I have some time. I really appreciate you taking the time to make these videos and answer questions. It is a huge help to the community. I guess Ill just wait until you have a video specifically for the 64 bit image setup so I don't mess it up 😆
You are a god send, thank you. If I used a 32gb when I first got all my setting done, am I stuck using only 32gb SD cards and having a 32gb image back up on my regular computer?
The easiest way is to use pishrink ostechnix.com/pishrink-make-raspberry-pi-images-smaller/ on your current image file, you can zip it to make it small for storing.
On port numbers. I ususally like to match the port to the instance number, so for instance2 I would use port 5002, instance port 5003, etc. It helps me remember without having to think too much. :)
That's a great idea! Thanks a lot
Well, I am trying to install a second instance and this is the error I get: cannot find a LSB script for octoprint2
I have seen that, but most of the time a reboot will fix it. If not try restarting the service. sudo service octoprint2 restart
On my 5 Pro's Ocotprint setup, I lost Prusa thumbnails. Have not been able to recover that functionality yet.
In PrusaSlicer 2.3 on the tab "Printer Settings" in the section "Firmware" there is a setting "G-code thumbnails". There you can put e.g. "16x16, 220x124".
Nice, glad to hear they added this in 2.3, that should help.
@@ChrisRiley If you used an entry in the printer .ini file before to create the thumbnails and keep the field in the gui empty, because you don't know it's there, this empty field overwrites the entry in the .ini file and there will be no thumbnail.
@@WalterLayher , I already have the thumbnails in gcode. Still cannot see them.
@@tonykyle2655 I only see them in the file manager in Octoprint. Used to be able to see them in the status display as well, but not anymore since a few days.
Hi Chris:
Do you have any tutorial for Prusa Slicer?
This is the only one I have for general info. ruclips.net/video/d4alPrZ3wG4/видео.html
Thanks a lot for your video, I have tried to set this up a few times now, hopefully with your help this will be the last, then the adding Octoscreen challenge begins. Maybe you could do an updated video and add that to your default image ??
There are so many different screens it would be hard. I do have an update video on screens coming out soon.
@@ChrisRiley yes, after trying to get Octoscreen going I realised how many different screens there actually is :( Still not setup. At least for now I am happy with a fully functioning Octoprint with Octolapse and TSD setup. I have burnt that image so at least I will have a good starting point after I mess the OctoScreen install up another 20 times this weekend :)
Can you make your desktop screen image available? I want to use it for a black t-shirt! Only members "in the know" will recognize the wearer discretely! Happy New Year from Japan!
Just for you! ;) drive.google.com/file/d/1ewNDcuKLMuF5521rMLspn7pEjZX8cyB9/view?usp=sharing
@@ChrisRiley Thanks Brother!
tried 3 different cables from the pi to printer will not hook up
What kind of printer board do you have?
@@ChrisRiley hi I used your image ender 3 pro all good except cant get cura hooked up to it for some reason
4.2.2 board
@@danmatthew1720 I am not sure how that works with Octoprint, does it send gcode over? If so just make sure you added the correct port to the config.
Hello Chris, I am 7 years old and currently getting into 3D Printing. I actually have a 3D Printer, because I got one for free from the school. I've fixed almost everything on it, however it was missing it's old micro SD card, and now I have no clue what firmware to install. It's a geetech prusa i3 pro B clone, I sadly d not know the name of the board as it was not printed on the board or printer, but it's a red board that's slightly smaller than those you'd see on official machines, if that helps. Would you happen to know what firmware to use, and if not, would you happen to be able to point me in the direction to finding the right firmware? For instance something like a website that explains what the firmware does for the machine, and how to stay safe while working with Gcode. I'm sorry for asking for so much but I figure I'd give it a shot.
BTW the printer powers on, and almost works, It just says "card insterted" instead of "i3 pro B ready" so I figure I need to put the right firmware on the sd
17* lmao but ill leave 7 cause it seems way more impressive
actually believe it or not i found a video right after leaving this comment that pretty much solved my issue, ruclips.net/video/cXOIoT8-zQ0/видео.html&ab_channel=Zachary3DPrints this dude has my exact same printer and he's updating his firmware
Awesome, Zack is a good guy. Let me know how it goes.
@@ChrisRiley oh forsure, thanks for the response!
Hi Chris, this was awesome. I just installed Octoprint on my Pi 4 and I love it. having multiple instances is a great idea. What size Pi should we buy for a 4 instance Octoprint with cameras?
4 printers and 4 cameras is going to be hard on any Pi. Good luck with your projects!
@@ChrisRiley Thanks, what would you say is a limit on how many instances would be acceptable? 2, one for every two USB ports?
@@ShahriarFarkhan 3 is about as high as I'd go
@@ChrisRiley Got it, thank you!
@@ChrisRiley Thanks!!
Super good stuff, but will be useful to see some octopi 0.18 multiple instances
Tomorrow is the day!
It's very frustrating, because the structure of files is very different from 0.17 to 0.18
Thanks Chris.
Thanks for watching
