5 years passed and this guide is still great
Thank you!
Thanks dude. When not even the prusa guide helped me, you saved the day. Great video.
Awesome, glad it helped!
Thank you so much, I tried other tutorials but yours got me there!
Awesome, thanks for watching!
I've never commented on a video before ever, but you sir did an awesome job. I tried to figure out all this stuff on my own based on the prusa and octopi web sites and came close, but they were missing some really key info that you had. Great, great job and thank you for making this.
Thanks David, that means a lot. Glad it was helpful!
I don’t have a Mk3 or a RPi Zero W... but I like the way you tell me about them! :) Great Video, and have a Great Vacation!
Thanks Mike! I will be doing some live streams during vaca, so I am sure we will chat soon.
First time finding this dude's KZhead Channel "Hey Guys, I'm going on Vacation for the Summer!" :(
Ha ha ha! Thanks for the comment, videos will start to roll again very soon. I am working on some as we speak, stay tuned. :)
Nice! I just got a mk3 and checking out all the different things you can do with it.
I am getting my first Prusa on Friday, thanks for the video. I will mount my Zero W during assembeling, saves me a litte time I guess.
Sweet! I am sure you will love the MK3.
Thank you for such a concise walk through.
You're very welcome.
Great work as always Chris. Cheers
Thanks, Fred!
Dude! How am I just now finding your channel?!? Great content, keep it up!
Thanks!
WoW! Slight shenanigans for the camera extension aside, this seems to be a very well designed integration. I am impressed with Prusa for making this possible. It is kind of a testament to how much value is added to the printer by OctoPrint. This is also an amazing demonstration of how the concept of Open-Source has allowed more than two companies to make money though the course of your build. The fact that you can succinctly present all of that in less than 15 minutes is no less amazing. Great Video.
Thanks man! I agree, the camera cable is a bit of a hack job. I agree, it's cool that Prusa even thought to integrate this at all. Very nicely done. Thanks for watching!
Awesome Video. Have a great vacation!!
Thanks Sam! Thanks for watching!
great video, I'm going to use your advice to do this.
Great! Yes, they are a little slow, but they work pretty well.
Thanks you Chris!!!!! learnt a lot from you. My first time working with Raspberry's and it works like a sharm.
Great to hear!
Great vid, everything worked as expected!!
Glad it helped!
Fantastic instructions, thanks! I did this with a raspberry pi B. All the steps for setup were identical, just had to print a different case and use jumper wires to connect everything.
Great! Glad it helped you.
Another fantastic video Chris, well explained and should be easy for most people to do. You might put a step-by-step process in the link below as a reference.
Thanks David! Thats a good call, I will work one up.
great video Chris I'm going to add this to my Prussia printer!!!
Nice! Thanks, they are very handy.
Hello Chris , I just subscribed to your channel, all your videos a very helpful, thank you so much !
Thanks for the sub!
Thank you for your job, everything is working and it's a miracle for me!
You're welcome! Great to hear!
Thanks :) the latest cases for the main board are designed so you can cut a section out, install RPI and glue it back ;)
Yes, very handy, I actually printed one the other day.
Do you have a link to this?
Fantastic! Thank you for the help!
You are very welcome!
Great video Chris.
Thanks Randy! How's the E10 working for you?
Chris Riley, it's working great. Using it today to print up legs for my lack tables. 😊 Already added heat bed wire support and a new fan shroud from CNC Kitchen.
Aweeeeesommmmmmeee!
Dude this is an awesome video. Thank you!
You're very welcome!
I used a USB OTG cable for all this and it works great on my CTC I3 clone.
Nice, glad it's working.
Nce video and congrats on 3.5k subs.
Hey James! Thanks man!
great stuff! enjoy your VACAY
Thanks!
Pretty cool, you can edit that boot.txt file and reduce gpu meme as well to reserve more RAM for octoprint to use...very cool setup
Thanks! I need to get in there a mess around on the Pi a little more. I will check that option out.
Great Explanations thx
Thanks Nicholas!
Excellent Vid, you saved me from going mad.
Thanks! Glad it was helpful.
Good video.. thanks!
You're welcome, thanks for watching!
Great video and very clear. I'd love to see a Mac version.
I wish I new more about Mac. Maybe someday.
I thought your soldering looked kinda rough then I got the kit in myself and man it's hard to get a beautiful soldering joint on these, that pad is so small and the solder would kindof wick up my pins!
Man, I am not very good at soldering anyway, but these are something else.
The header pins you linked are 6mm in length. I am very disappointed that I did not check that. I ordered them and was surprised that they were that short.
That's a bummer, I just checked the link, it takes me to dual 20's. Maybe they sent the wrong ones? www.amazon.com/DIKAVS-Break-Away-2x20-pin-Header-Raspberry/dp/B075VNBD3R/ref=sr_1_6?ie=UTF8&qid=1541968179&sr=8-6&keywords=dual+pin+headers&dpID=61nSEH42RSL&preST=_SY300_QL70_&dpSrc=srch
Very well done Chris, Thank You. Is there a way to power cycle the Rpi from the OctoPrint UI?
Thanks RJ, I don't think so. If there is, I would very much like to know how.
Yes there is. Click the little power symbol in the upper right and you can reboot or reset.
Is that really power cycling the Pi though?
You should be able to do it from the MK3 UI by disabling the RPi port.
great vid! thank you for sharing. Please note however that Octoprint seems to not recommend Raspberry Pi Zero W...and suggests Raspberry Pi 3B. "Recommended hardware: Raspberry Pi 3B. Please note that the Raspberry Pi Zero W is not recommended since severe performance issues were observed, caused by the WiFi interface when bandwidth is utilized (e.g. the webcam is streamed), negatively impacting printing results."
Thanks! Yes, it is a bit slow.
My experience is that the rpi zero W is at the edge of what you need in processing power. Adding a webcam definitely puts a high load on it so it's pushing the edge. The zero W can work well and reliable with Octoprint, but you might want to go easy on the setup (no webcam) and only install a few plugins. Note: For that reason the rpi zero is also not officially supported by Octoprint. My main prniter is running Octopring on a rpi zero 2 W, which is more than capable 👍 (also has 2 webcams connected)
Thanks for your insight!
Ok Chris, I got it working. Just use the "octopi-wpa-supplicant.txt" as you have it (unstated). Also maybe I don't need a part for i3 MK3 Prusa.
I think the new prints come with that part, if you need it you can get them from the prusa files. www.prusa3d.com/prusa-i3-printable-parts/
Thanks for this video. Yet another great and helpful video Chris! I used this video along with the directions from Prusa to get my MK3S setup with a PI Zero. Works great! Thank you! Anyone have any recommendations for a webcam to purchase?
Great Pat, glad it helped. I have never really found a webcam I liked. With the Pi zero you need to stay pretty low res as well. I use a C270 at 800x600, works ok.
@@ChrisRiley Thank you so much Chris! After an hour of usage, I'm starting to realize that the Pi Zero is no powerhouse, that's for sure, so your resolution comment makes sense to me now. But I'll still give that webcam a look. Now, I'm using a cheap Eufy "Indoor Cam" to view my prints, which works great since I already have other Eufy Cams around my home, but I have to jump over to the Eufy app to see it print. I just wanted an integrated solution to view status and prints in a a single Octoprint app. I appreciate the response and the information. :) Thanks again! :)
Hey @Chris Riley. Did you use a regular usb converter/extension? I did the same setup as you, and have been struggling with an "OTG" usb extension cable. I cannot get the webcam to work no matter what I try. Wondering if I am using the wrong type of usb converter cable....
@@PatJones82 I have been using these. www.amazon.com/gp/product/B00GM0OZ4O/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
@@ChrisRiley Thank you Chris! I'll order those and give one a whirl! :) Much appreciated!
Nice video Don't you need to expand the file system on the SD card ? Id be interested to hear how you get on with the camera From what ive read the Zero W doesnt handle camera's too well
The latest Raspbian releases (on which OctoPi is based on) automatically expand the file system on first boot.
Like Chan was saying, it seems to take care of that for you now. There is still the option in the CLI menu if you need it. So far so good on the cam. I'll report back if I find issues, thanks for watching.
Yep, old but gold video. Thanks Chris. I've watched your take on setting up WiFi on the Prusa as well as another. I don't see why I can't install Octoprint, configure the Pi and get everything set up without the use of Putty etc, as it sits connected right next to the PC . . . THEN install it into the Prusa. What am I missing here? I bought a Zero W on the strength of your video then I find it is NOT the recommended model, as winandd8649 below mentions. Same notion occurred to me . . . if I want to add a camera I would want the faster 4 core 2 W version so I've gone and bought it too. Now I have a Zero W with no project for it. Pays to do more research AND check video dates BEFORE reaching for the wallet.
Thanks for watching! Yeah, this is a pretty old one. The issue with Putty is that GPIO connection. If you don't disable the blue tooth interface, it interferes with the pins. If you were using USB, no putty needed.
Great video! I just ordered my MK3s, is there anything i need to do differently from the MK3 installation?
Thanks! Nope, you should be all set! This will work.
There is a case for the Prusa that has an integrated opening in the back of case to intall the Pi. I printed and installed it. Makes access easier if ever needed.
Edgar thank, I just printed it. I’ve been busy so I’m still getting the stuff together for the job
Thank you for the detailed instruction. Planning to buy a prusa mk3. I am using octoprint since years successful and never want to miss it. Also there are some apps for your smartphone for octoprint access. What i was missing in your video is the fact, you had to shutdown the pi before you switch the power off. Otherwise the sd card of the pi sooner or later will get corrupt. Anyway i wondered if there is a feature that the prusa will shutdown the pi?
Hmmm....good question. Not that I know of, but I will look around.
Very good point! @Chris - Did you find any info on this?
You can also use AngryIpScanner to get the IP of the raspberry, or preconfigure a static IP in the SD card when you flash it.
Thanks :)
thanks for the instructions , i wanted to ask can i still print from the sd card on the lcd or am i obligated to only print through octoprint server?
Yes, you can print for either while this installed.
Hello Chris, I have to tell you... this is an awesome video! It is the only way I could get my pi zero w to work! Sadly, my pi zero is doing weird things. I have had to switch to my 3B+ pi for my MK3. Is there any internal settings like the zero that I need to do... or is it just plug in USB and go? :) Thank you for all of your videos and how helpful they are! Have a great day, Charlie
Thanks! It should be ready to go, no changes. I have 2 zeros I use. Both work, just a little slow. I do use a number 10 sd card for what it's worth. What is it doing?
@@ChrisRiley... it will not connect or I should say... stay connected, and I can't install plugins... I may just redo the micro in it...
@@charliebowen4232 right on....it should be the same as all the other pi's.
@@ChrisRiley - wanted to let you know... I wiped micro sd back to nothing and rebuilt Octopi... all is working great! Again that you for this video! Really appreciate you and all you do for the community!
Awesome! Glad that worked! Thanks for the kind words, I am more than happy to help where I can.
Hey Chris does the camera work fine with it too if it does then ill just buy the pi zero it's cheaper and more compact
The camera doesn't work so well. Sometimes it also depends on what board you have. You milage may very on the zero setup.
All your videos are soooo helpful. I'm already subscribed, but if I could, I'd subscribe again.
LOL, thank you!
Any way you can do one on the Banana-Pi-M2Z for Prusa MK3 as bit more cpu power?
I am not sure what that board is.
The wifi failure on the Raspberry PI 4 continues many have walked through the install setup but no one so far has been able to resolve the issue of failing to connect to wifi. Many say they have successfully carried out this setup and those that have been kind enough to help only to have them walk away with their hand in the air. Some also say they got it working and it must be something on my end and I agree. Eventually, others will be searching for solution and stumble onto this post and channel.
It could be some router settings as well. Compare yours to these. photos.app.goo.gl/FWsBVoCSD5JpH4nZ8
Damn thats a lot of programming
It is, not as easy as it should be.
Is it possibile to connect Rpi 3 with same pins on Einsy board to eliminate external power supply(there are two 5v pins,two ground pins,Gpio 14 an Gpio 27 as i can see)?Does Einsy board provide enough power for Rpi B+ or Rpi 3?Thanks for your answer,keep up the good work
Yes, it is possible, I am not sure how much power it will support, but I think it would be enough.
I think your dual header pins link is incorrect. It's linking to GPIO pins that are 2x20 (pins themselves, not length) and the lengths are only about 10mm.
Thanks Jeremy should be updated now.
Why didn't you use the Prusa-version of OctoPi (PrusaPrint)?
Whoa! Nice! I didn't even know there was one. Thanks for the link.
The biggest difference is that the printer is already configured in Octoprint, so that saves some time and confusion :)
Thanks again, I added the link to the description.
You're welcome. Enjoy your holiday! Have a great time!
Good video but Prusa needs to implement Wifi on their printer. For 750USD for the kit 10USD for the pi0 should not be an issue... I mean they do not have a touch screen in 2019...
I kinda thought the same thing, but I think that's how the Raspi foundation is setup, they won't sell in bulk to other companies. I am not sure how that work, because Mosaic does it. I know they are very picky about people buying for than one zero at a time in the US. But agreed, they could have thrown something on there for cheap.
Personally, I don't really care about them adding wifi on the printer. Just hook up a raspi using octoprint and the entire issue is gone.
@@HushangA you make it sound so easy got a link(ez link)?
@@MaxGoddur Step 1 ) Download octopi from octoprint.org Step 2 ) Flash to microSD Card using etcher Step 3 ) Once flashed, modify octopi-wpa-supplicant.txt with your wifi info Step 4 ) put said microSD Card into raspberry pi and boot it up Step 5 ) plug in USB cable from raspberry pi to printer and open the webGUI for octoprint Step 6 ) You're done. I can get this from start to finish under 30 min (longest part is actually downloading the octopi image)
@@MaxGoddur This also hits the same points, but in a video form: kzhead.info/sun/krx6c9V9eGOee40/bejne.html
looking ot find the orange pin mount kit you showed but not able to locate. Do I have to print or order?
Hey, you can print it. www.prusa3d.com/prusa-i3-printable-parts/ It's in the MK3 parts file. It's called rpi-zero-frame
Chris i know this is an old video but is this the same for a pi3b+? I set the static ip address but then you go through 2 more steps. Are those needed as well on pi3b+?
Yes, if you want to use the GPIO pin's it is. If you just use USB, then no.
@@ChrisRiley thank you sir. Your videos have been so valuable to my 3D printing journey!!
the correct way to allocate a static ip is either : 1) assign it as static in your router 2) use the method here and reserve that ip in the router. otherwise there is a chance the DHCP server will assign the same IP you made static to another system and they will conflict
IP conflicts are the worst.
Any other place i can get the 20mm dual header pins that doesn't take months to deliver? Thank you

Using a dhcp assigned address for a static can cause a problem as the dhcp server may re-issue it to some other device. Generally it is better to assign fixed addresses either in the router or to use an address that is outside the dhcp pool.
Agreed.
HI Chris, ordered my MK3S+ yesterday. Your WIFI video here came out about 1.5 years ago. Is everything in the video still valid? Are there any updates I should be aware of before I get started? Thanks for help and great videos!
Everything is pretty much the same, no issues I can think of.
@@ChrisRiley Awesome, thanks much for the reply Chris! My Prusa is on backorder for 3 to 4 weeks but, I look forward to following your video step by step when it arrives. Have happy and safe holidays!
Hi Chris, I just finished assembling my MK3s last night. I watch the video and read most of the comments, I would like to ask few questions if you don’t mind. If I decided to use Pi 3b to have more power and connecting it through USB port, will all the MK3s feature works? Cause I read somewhere that Octoprint takes over the OS then some of the sensors will not work. I don’t really need the wifi, but cool if I can have it. Need your opinion on that.
The Pi3 will work just like the zero, the only feature that won't work is power off resume, that's for all printing with octoprint.
Chris Riley , if I’m using octoprint only for monitoring and I print from SD card, will the power off resume work?
@@pataroppusunggu8443 Yes it will.
Chris Riley, thank you
Fantastic tutorial. Ive used this to install in the past without issue. However, after my Octoprint became unresponsive when booting (issue with plugin found in errorlog) i decided to do a clean install. But for some reason after i flash with Win32 it creates another partition, i have removed this numerous times but every time it does the same. I tried installing the Pi with this partition but it will not connect to my network (i have checked SSID and password 3 times). Any ideas my friend?
When you install it should create 2 partitions, this is so you can edit it from windows as well. So having two should be normal. Let me know if that makes since with the issue you are seeing.
hi, I know this video is old and not even sure if this will work for my Prusa Mk3S + but i want to try it. where can I print that orange shell for the raspberry pi?
Hey, it will still work, here is the part. www.printables.com/model/57217-i3-mk3s-printable-parts/files
Can you do an update for this for prusalink?
Here you go! kzhead.info/sun/ksNpmtqbeaqkiXA/bejne.html
question.... when setting up the WPA, are you making a network name and pw for the printer or does your home router and pw go there? only part that has me completely lost. everything else is pretty straight forward.
Your home router and pw get entered in there. The setting is inputting the octopie your home network settings so it can connect to it. Once it's on your network you will be able to connect to the printer and continue to the next steps.
You got it Frosty! Thanks for your help.
Can anyone confirm that the steps are the same for the newer Zero 2 W? I mean I assume they would be but you know what they say about assuming.
Yep, go for it!
Chris, any issues with this since putting it together? I keep reading on the Prusa subreddit that the Zero works great until you attach a webcam to it, at which point it seems to crap out more often than not? I've got a Pi 3b that I can build, but love the self contained option here.
I love the zero setups, but the cam does become an issue. I run a c270 at 640x480 and it does okay, but as you can imagine the quality isn't good. Anything more than take, it starts to crap out.
I HAVE the Pi Zero W but I have not used it yet as there have been discussions that it is not "powerful enough" to use for this situation. Even on the Octoprint page it tells you "Please note that the Raspberry Pi Zero W is not recommended since severe performance issues were observed, caused by the WiFi interface when bandwidth is utilized (e.g. the webcam is streamed), negatively impacting printing results." It has been said that IF you are going to also be using a cam with this setup to actually supply the Pi Zero W with its own power and to remove the power pins from the header as the Einsy board is not able to supply enough power. Care to give your input on this?
These are probably good tips to follow. I have never had an issue with the setup. I have two running with cams and no failures yet. The Pi zero is probably right on the edge of what it can handle, but again, all the testing I have done seems to work just fine. Best practice is not always the practice I follow. :)
Where can I find the .stl for the spacer?
Hey Aaron, you can find them in the MK3 STL zip file. www.prusa3d.com/prusa-i3-printable-parts/
The pi zero is not recommended to be used with octoprint. It says it specifically on octoprint's site. It says it at 3:00
You are correct, but it does work. I do a lot of things to octoprint that isn't recommended. :)
Hey Chris does the octoprint not lav with the pi zero I'm in the uk and what can you recommend for octoprint under £20
It works okay with pi zero, it's just kind of slow.
DOPE af homie! Get my mk3 in end of july have a pi zero w laying around and utilized it for this easy tutorial. Next project is the enclosure for the mk3 any tips for the mmu2 for the enclosure?
Thanks! No tips yet, I have the lack enclosure, but we don't know the sizes of the MMU2 yet. I have some contacts over at Prusa, I will see if I can get some early specs.
Chris Riley there’s already a mmu + lack table enclosure Thingiverse update
Do I have to have wifi on my router to make this work or can my computer talk directly with the pi?
You will need a router.
Is that serial connection faster than the USB?
In think it will be about the same. Not sure.
@@ChrisRiley If you ever compare them, drop a comment 😊
Hi Chris and other. As soon as i plug my pi in the mk3s it isn t turning on. As soon is I unplug it from the board it turns back on again. I checked the pins and aktivated the pi port on the mk3s. What could it be ? Would be nice to here from you.
You mean a Pi 3 B or something like that? Not a zero, right? It turns off when you plug the USB cable in?
Just snip off a set of 4 pins and a set of 2 pins, this will give you the 6 pins you need, and no fiddling around with parts that spin in their socket.
Great tip!
Make sure you check the OctoPrint page BEFORE you purchase the Zero W. I didn't, went to download the image and found the big fat warning. "Please note that the Raspberry Pi Zero W is not recommended since severe performance issues were observed." It is a single core mini computer with a slow AF CPU. Great for other projects but not to control a 3D printer.
They don't recommend it, but it actually works pretty well. Just a little slow.
Great video, when I enter “sudo reboot now” and click enter, it come up with a “fatal error” saying “Remote Side unexpectedly close network connection” What do I do?
That just means it's rebooting, you will be able to reconnect in a few minutes.
Ok thanks so much for the help! I will try that.
I got it to work, thanks so much for your help!
Chris will Octoprint run on a Pi Zero for an Ender 3?
It will, it's slow, but you can use the USB port on the pi and printer.
Chris two questions from a Prusa NOOB.. Is the octopi-wpa-supplicant.txt supposed to have "txt" extension or "conf" or nothing? I cant get it to find wifi at present. Secondly, is there a file to print the plastic part? I want to just load it on the SD card and make it. Otherwise a good lesson.
I see you found it was txt, I should have mentioned that.
just wondering, What's the most reliable 3d printer you own?
My Prusa MK3's have always been really solid machines.
@@ChrisRiley Thanks

Both seem to work, go for 20mm.

Yes.
Chris wondering if you have noticed many folks posting on the subject of Octopi raspberry pi4 not connecting to wifi? I just bought one and can't get it working via wifi works fine wired ethernet only problem location does not have wired jack just wifi.
I haven't heard anyone having issues. Go back and re-check your wifi name and password, it trips me up sometimes, it's case sensitive.
@@ChrisRiley someone suggested I try rolling back to 0.16 but that was a bust. Guess there is just no solution?
@@MaxGoddur Can you turn off your wifi security and try it? Just for a test?
@@ChrisRiley yes many times checked and rechecked in the supplicant text file.
@@ChrisRiley did not know you could turn off wifi security is this something in the router?
followed your tutorial perfectly and everything seems to work. I can print and connect to the printer with octoprint but when I try and install plugins I get this error. "It looks like OctoPrint has currently no connection to the internet. Due to that it's not possible to install new plugins from the plugin repository or archive URLs." Any idea what is going on?
Hmmm, maybe a routing issue. From command line, can you ping Google? Ping 8.8.8.8
@@ChrisRiley says network is unreachable
Yeah, this is almost always something with the wifi password or SSID. I know you have probably checked it 10 times already, but they are case sensitive, you might take another look.
Thank you for your replies. I just gave up on the pi zero and went with a Pi 3 b+ and it works like a charm.
@@cfullwood Nothing wrong with that, it's much faster anyway.
Hi Chris, I will have a MK3S soon and I would like to add octoprint to it. I read a lot of negative stuff about using a RPB Zero W for this. Apparently the makers of Octoprint are not really in favour of this. You have a lot of experience on this: what would be your advise? Are you still using the RPB 0W with the prusa MK3, and does it have some limitations? Some are even suggesting that the slowness of the RPB0W could even have a negative impact on your print, not sure how this is even possible. Thank you!
I still use them all the time. There are some limitations. I suggest to not use a camera and if you do, keep it very low res. If the ZERO gets overloaded it will cause the gcode stream to stutter and cause bad prints. The way I see it, it's cheap, if it doesn't work out, no big lose. Personally, I like them.
Do I have to use a Raspberry Pi Zero? I have several Raspberry Pi 3b+ laying around that I can use... is there any reason not to use that?
No reason, it will work, you will just have to work something out for the pin header.
Hey Chris. Do you think this is still the way to go for adding wifi to a prusa mk3 ?
I think it's the best way, if you can get a zero 2 it's even better.
@@ChrisRiley I have the big raspberry pie 3+B. You think that would work ?

@@ChrisRiley This is why you're the man. I just finished building mine and installed it yesterday. I forgot to buy the adapter when I bought everything. Now I have to wait 7 days for it to arrive. I saw an arduino adapter to allow for two ribbon cams at once for octo printing when I was shopping for it but did not want to try it just yet. Future build perhaps. I would really love it if you share how to extend the OctoPi setup to use a full 32 GB or other size card. Now that would be cool. I have two tutorials I found yesterday and I am going to try them out soon on my 32GB SD card maybe tomorrow. I will let you know how it goes. Going to back it up first though.
Oh and I forgot to tell you. I got the dual header pins instead. I then cut it to size and pulled out the pins I didn't use. It seemed to be easier to solder the pins in. I used a gator clip to hold the header in place and man it came out nice.
@@The_Digital_Samurai Yeah, the dual headers would make it much easier. I don't know about 32g, I would have to do some testing as well. I though it was anything over 32g that was a problem, but maybe not. I will look into it.
@@coolranchluke I actually got it to work. Setup the Ribbon cam first. Download Multicam plugin. Install the USB one and follow Chris Riley's dual cam vid.
These settings the same for MK3S?
Yes, same settings.
Hi chris have a happy 4th July my friend
Thanks Paul! Hope you have a happy 4th as well.
I bought the Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth (4GB) and have been having a problem getting it to print through the serial port on my Prusa MK3S ...Any Help?
Are you using USB or GPIO pins? If USB, make sure your RPI port is off.
I have the exact same set up you do. However my webcam is not clear. its black and white and very pixelated snowy almost and diamond shaps instead of normal pixel squares. At first it did show it clear but the printer would not connect but after the printer connected and was opperational the webcam stream went to shit. What else can I try to fix this? I followed video but not sure what else to try.
figured it out, great video! thanks
Thanks! Glad you found a fix.
@@ChrisRiley Thank you man! Awesome video, super happy with this set up it is awesome!!!
Great intructions. I got it all to work but then suddenly it stoped working. I reinstalled everything but still no wifi connection. Does somebody has any idea ?
Hmmmm, you didn't update firmware on the prusa or anything at all?
Nope i didn't. It suddently stoppedconnecting to my Router.
@@HenrikHuehn Sounds like the zero crapped out maybe, try removing it and powering up outside the printer.
Thanks for your Support. I tried but still no connection. IT shows up when i connect IT via USB, so maybe the antenna is broken. But i don't know why this should be the Case. It was working for like 40h and then suddently stopped connecting ... :(
@@HenrikHuehn Sorry to hear that.
In the video it looks very easy, unfortunately I couldn't manage to connect none of mine two Zero W to my wi-fi, I tried everything what I could find on the internet. Obviously my Prusa MK3 is not designed for Rasperry Pi. :(
Where did you get stuck?
@@ChrisRiley I managed to sort it. For some reason I couldn't get wifi working uncommenting and entering my network info. The other issue I faced was that the latest version of Octoprint doesn't work with Zero W, hence I bought a Pi 4. It works perfectly. Unfortunately I still can't make my Playstation Eye to stream any video. I have spent 3 days tinkering. Still no joy.
My IP is not changing to static. I Typed everything in like you did (just with my router adress) and i also checked if is was saved. After reboot, it just keeps beeing dynamic. I will try to redo the whole procdure now. Maybe you have an idea why it didnt work?
Not sure, make sure your syntax is just like mine, no spaces. Here is my file.

One question - I heard that the ZeroW was somewhat marginal for handling Octoprint and the video camera. What has been your experience on this combination?
Meh, it's slow, but it works. I use a c270 at 800x600 for monitoring, it works ok for what I use it for.
@@ChrisRiley Good to know. Thanks.
@@ChrisRiley Chris, what is slow? I mean for a noob that does not have one yet, what is it that is slow. Trying to understand if I want to add the external v 3B board but not understanding exactly *what* is "slow"? Can you elaborate, please?
@@mechsavvy9067 The web interface, you have to wait a minute or two for it to populate. The 3b is almost instantaneous.
Chris Riley thank you. Then that’s a no brainer for me. I can deal with another box and some cable management no problem. Cost difference is trivial.
whats are alternative you can use instead of usinga raspberry pi?
