Chris always coming through! Thank you!
Thanks for watching!
Exactly the information I was looking for! Just got an MK3S+ for Christmas and am so excited at the potential!
Glad I could help!
Just got one of these, your timing is on point ! Thanks Chris.
Great, good luck!
Used this to upgrade the rPI-Zero-W in my Prusa to a rPI-Zero2. Thanks!
Nice! Yes, a great upgrade.
Thanks for the video! I'd be interested to see a follow up on the full MMU setup with Octoprint and the RMU. I think it would be interesting to get some feedback after time in that configuration.
Thanks for the idea!
Good details, thanks for the rundown! I have this running smoothly on my MK3S(+/-) with an HQ Pi camera. The HD stream isn't as smooth as it was on a 4, but the web interface seems about as snappy otherwise, at least usable. I'm happy to use the Pi 4 elsewhere and neaten up the printer.
Thanks!
Just installed a zero 2 on my mk3 last week. Working fine so far but I haven't tried any time lapses. Thanks for the testing
Great to hear!
Nice video Chris. I really like how the pi0 fits on the board. Be nice if other vendors did that. Keep up the great work.
Did you find the printed parts only I can't find them still searching.
Thanks, will do!
Nice info about camera settings 👍👍 *FINALLY* got mine outputting a 16:9 aspect stream. 💖💖
Great to hear!
@@ChrisRiley I've been watching your content and subbed for a while now. And while I only have an ENDER 3 V2 - I do get a lot of info from your channel. 👍👍
@@3ATIVE Thanks a lot!
Using it for octoprint for a month and some, it's really good. The pi camera works really well with it too, super smooth. I skipped the USB connection and use a direct serial connection to an skr 1.3. The guides for the old zero work just fine for this.
Thanks for your input!
Hey Chris, just a follow-up. The issue was with my MMU2 signal cable so I ordered a replacement from Prusa, all is fine now. I also installed a thin copper dye on the Raspi Zero 2W, and it dropped the operating temp to about 61 degrees C, with the camera in use. Thanks for your detailed, informative guide, as always!
I'm glad you got it going.
Using the Zero 2 on my RatRig for Klipper and it works fantastic. Great little board priced at a fraction of what the Pi 4 is.
Great!
Many thanks for that video. You got now a new subscriber.
Awesome, thank you!
Hello Chris, again a super informative video. If I wasn't already using a Raspi 4B with 4" hyperpixel touch dsiplay (following your instructions to get it running) I would put in the Pi Zero 2. I would be interested if there will be a video about the MMU2S soon where you talk about problems and advantages as well as tips what can be improved. Please keep up the good work
That's a good idea, Thanks!
New to Octoprint and Pi’s. I have the Pi Zero 2W on 2 printers and have already done some longer prints with good results.
Great!
Yet another great video. Is there anyway to force the PI to shut down properly when a power outage occurs? I don't have an MK3, but my printer does have one of the UPS add-on boards. I find every time the power goes out, I have to re-flash my PI's SD card.
I'm actually looking at this right now, with Marlin, I think there might be away we can do this.
Good video. I may try one for Klipper - the problem now is finding one at close to the $15 price.
Thanks Dave!
Hi Chris, outstanding video as usual. Thank you. Would you have any concerns with using the Pi Zero 2 in an enclosure mounted to the Prusa MK3S+ main board, given your comments on temperatures measured on the Zero 2 PI? I am printing PETG mostly. Did you ever get a chance to see if a heat sink on the PI Zero 2 processor would fit when mounted to the Prusa main Board to help with heat dissipation? Thanks for your help as always!
Thanks! I never did get to test to see if it fit, but I don't think there would be any issues. They can run pretty hot and still operate optimally.
@@ChrisRiley Great, thanks Chris… Now to see if I can find a Pi Zero 2 at a reasonable price. Thanks again!
Really curious to see how well this will run klipper!! would like to see a direct comparasion to something like the pi 3b or even the pi 4 .. but GREAT vid!
It's runs klipper perfectly. You can get away with running klipper on an original rpi0 if you use mainsail or fluid.
😁👍
Great video! But how exactly.did you connect the webcam while the Pi is in the electronic board of the printer?
I use a L shaped plug and just run it behind the board, not great, but it works. www.amazon.com/StarTech-com-Right-Angle-Micro-Adapter/dp/B00K4RZQWQ/ref=psdc_306629011_t1_B00LN3LQKQ?th=1
Thank you!😀
Thank you for watching!
Yeah, but where can I find em? Lol first to comment first to gripe. Love the new studio my man.
Thanks!
I used a pi 0 w on my Ender 3 a few years ago. At first I thought everything was good, and it was depending on the job. Things with small radius curves or just a lot of short print moves in succession left a lot of blobs due to the 0 w not being able to feed the printer fast enough. It's possible there is less overhead or latency using the GPIO connection though. I think I'll try to find a Zero 2 and give it a try.
Good luck!
@@ChrisRiley your gona have different performance issues, but still issues. The 2w does not properly support octopi
@@ljohnso16 Interesting, I will keep testing and see what happens.
I have a rpi zero 2 running mainsail and it performs flawlessly
Great!
@@ChrisRiley Its good that you made a video on it when I set up mine the pi was brand new and i had to figure it out on my own. This will help a lot of people in the future!
Thank you chris
Thank you Paul
@Chris, can you please test again the temps but inside an enclosure? I have the LACK enclosure setup and had to put the PiZ2 outside because I got some readings at 85-90 C. I even tried to use some dupont cables as extension so I can put some heatsink on the board, but that just lowered the themps to around 80C, still to hot for my taste. I'm thinking on using a long ethernet cable I'm not using anymore to just put the Pi outside the enclosure.
I'll work on it. Thanks
Would love to see a similar guide for the Prusa Mini+
I'll see what I can do.
I have used OctoPrint on a Pi Zero for the last year and haven't experienced any problems. However, I was looking to improve startup times and ordered a Pi Zero 2, so really appreciate the video that confirms the improvement. I must say I never really understood the attitude of the OctoPrint developers in regards to the Pi Zero. Some users like myself just want an easy way to upload and kickoff prints and nothing more.
Pi Zero is slow enough it can cause issues on some main boards. But like you, I have never had issues with it.
With a touch screen and mounted on the board. Will I have enough juice from the printed or the added need from the touch screen will be to much. My understanding it was quite limit just with the cam.
For a touch screen, I would think you would need an alternate power source.
You the man Chris.....
Thanks!
Overall a pretty good video, just FYI, there is no such thing as a "Gigahert." The term for frequency is GIGAHERTZ (or cycles per second if you're an old timer RF person) - named after a person so 1 GigaHertz is 1 GIGAHERTZ the "z" does not make it singular or plural.
Thank you
Came here to say this. Made me wince each time! 😜
I'm a bit confused on the camera and the Cable Matters 2-Pack Micro USB OTG Adapter. Do you plug it into the PI as well as power and then the camera plugs into it or is the link just showing the wrong item?
Sorry, that's because it was the wrong link for the cable. I have updated it. geni.us/Gsfh
So is the microSD interface on the Pi Zero 2 any faster than the one on the Pi Zero? On my Pi Zero W it maxes out at 20 megabytes/second, using a Sandisk Extreme 64GB microSD with 160/60 read/write speeds, so was roughly equivalent the access speeds on the Raspberry Pi 3.
I would say it's about the same as before, pretty much just like the Pi3.
Is the procedure the same if using other fruits alternative boards, where pinout were different ?
It seems like every version of these boards are just a bit different. I have to google around to find a walkthrough to make them work.
Chris, I have the Rasberry Pi 4 with the OctoApp on my phone. Every time I go into the OctoApp, it stops my Prusa Mk3 from printing when it connects to it. Then I have to start the print all over again.
That's not good, I don't know octoapp, but it must try to make the print connect every time it starts. Try to find an auto connect setting in the app and turn it off.
Hello Chris, what upgrade do you have on the left of the prusa for the MMU2, seems like a buffer for filament.
Yes, that is teh RMU buffer, it works great! kzhead.info/sun/p72eebmenV9paKM/bejne.html
@@ChrisRiley Thanks, love it.
I already had octoprint running on a Pi3 and just swapped out the sd card. IP address changed and forgot the password but a little ssh magic and it is running fine. YAY
I'm glad you got it going!
@@ChrisRiley I'm afraid the link to the micro USB cables force the cable to go the opposite direction. Meaning it goes toward the top of the main board enclosure. I can make it work but I just wanted it known.
is there a way to set this up over lte as i dont have any wifi at printer?
Not that I know of, you could set it up on wifi, then after that use octoeverywhere via LTE.
@@ChrisRiley thanks i'll look into that. Appreciate the reply .
Question. If i want to park nozzle in the same place where it ran out of filament just 10mm above, will this work ? #define NOZZLE_PARK_POINT { 0, 0, 10 }
Yes, that will do what you want.
@@ChrisRiley that moves XY to 0, which is home. Maybe I am looking in the wrong place ? Once I hit resume, it homes XY and then moves to resume point and lowers by 10 and continues to print. Need to prevent it from homing after filament ran out alert and after I hit resume.
You're right, I didn't think of that. I have been playing with this a bit. Try this, #define NOZZLE_PARK_POINT { 0,0,20} Then add this line: #define NOZZLE_PARK_Z_ONLY See if that does anything.
Can the Pi Zero 2 also be connected directly to my MKS Robin e3d? I know it can via USB, but via UART like you did here?
Yes, works the same. Use the TFT Pins. Good Luck!
Am I able to do this with my Pulse XE!? 🙏🏻
Not unless it uses an Einsy with Prusa firmware, you could set it up with a custom Marlin config, but it would take some work.
Please disregard. Thank you so much for this step by step video!
Did you add the /dev/AMA0 to your settings page?
I cant find any raspberry pi zero 2 on the market, where can i buy it? (Shipping to czech republic)
They are very difficult to find right now.
I used Pi0w before same Mitch Crane, after one particular print of small m3 screw hole where the printer stuttered, I immediately changed to pi2. Now I know why the octopi veterans said "it's a bad idea". It is because of this. But in a very vague explanation, not enough information, as if, a printer's accuracy are measured in good, bad, mediocre, perfect instead of 0.1-0.4mm tolerance capability
yes, the outcome from using the Pi 0 can be unpredictable. A lot of times if depends on the serial chip the mainboard uses.
the best!!!
Me or the Raspberry Pi Zero 2? 😂
its you 😂
HOLY CARP!! the world is ending, Chris didn't print a benchy!
Ha!
Is there an advantage to using the pi instead of just running octoprint through a pc?
Yes, if your PC goes to sleep, updates, crashes a program, lack of ram due to to many programs open, cat pulls a cable, etc there goes your print job. A pi is dedicated and short of the power going off or the cable coming out, you're golden.
Like the @TheMidnightSmith said, it's nice to have a dedicated device for octoprint so you don't run into usual PC type issues.
how about a raspberry pi zero 2 W on a mini
Yep, should work the same.
The Zero 2 has the same chip as the 3b+, just clocked at 1ghz instead of 1.4. If you can deal with the cooling, somehow, there is no reason you can’t overclock it. I love it for the space saving size and the lack of unused ports, unlike the the regular version of Pi. I was using the model A 3+, but the Zero is half the size and cheaper.
Thanks for your insight.
amazballs
Lol! Thanks!
Ahh the coffee jitters.
Yep 😁
I use my Raspberry Pi B gen 1 with Octoprint. It only has 256 of ram.
Thanks for sharing!
@@ChrisRiley you have a video on the SKR Pico coming soon?
@@dleyba4945 Yes, I hope to soon.
@@ChrisRiley That would be great! Your videos are very thorough.
I tried with a pi zero a few years ago, but got crappy performance so quit using it. I may just get one of these because I have been spoiled with the duet web interface on my other printers.
Let us know how it goes!
@@ChrisRiley I got the pi zero 2w yesterday. I took the sd card out of my old pi zero updated octopi to the latest version and octoprint to the latest version, made the 2 changes necessary to make it run with the mk3s. The web interface is still slow to load for me, but it is handling a very complex print right now without issues. Nice to have the ability to upload and start a print without moving an sd card back and forth now.
How about a fan to cool it?
Sure, if you can work it into the config, I am going to be doing some testing.
The Pi will just throttle a little when it gets hot, it will still have enough umph to get the job done. 99% of the time you don't need to worry about the Pi get hot it will look after itself.
Thanks!
You mean the Raspberry Pi 2 zero W?
Yep
Dezember 2022 and the Zero 2 is still out of stock.
Bummer!
Huh? You mean Zero 2 W?
👍😁
the rpi 2w works with octoprint for 2-4 days then it becomes corrupted it wont load stl files or start prints. The web interface goes offline regularly. Octoprint devs have no idea and dont even acknowledge this is a problem. If you are reading this get a 4b because the 2w is not powerful enough.
Thanks
Always put heatsinks on Pis. And probably a 5v fan. Edit: meant to say "I" always... 🤦🏼
Thanks!
@@ChrisRiley I left out the leading "I" in that comment. It makes a good 10C difference in mine.
Thanks for this one! We have some eight Prusa i3mk3s printers at our makerspace and we're currently using pi 0 w. It works - ish - with the pi camera (no need to even try USB) - but plugins like PrintTimeGenious (which IMHO is a must, since the standard estimation is a bit like xkcd.com/612/) does not. I guess we'll try to change one to the pi zero 2 :)
I'm glad you liked it!
