“Make sure you like that smash button”. Man, I gotta use that one. :)

Great update Good points And a great little RPI :-) Thanks for sharing your experiences with all of us :-)

Good info. Great tech application analysis. Always a fan. May need to get a few of these.

Just ordered one to convert one of my printers to Klipper. Thanks Nero.

Glad I managed to grab one before my local supplier was out.

I bought one for my future V0 build. Can not wait to try it! It will be quite the upgrade from my old JGAURORA A3 I guess 😁

I like it and have one that I plan on using it with a Hyperpixel 4 with klipperscreen soon. I just need to design the case for it now

I just bought on for a used Monoprice Mini V3 that i got for cheap, and im going to install it with a picam and another board in it. Then i will klipperize it and see how fast it can go. Thanks for that great review. That helped with the buying decision.

Nice:) I'll be sticking with my Pi4.

I installed klipper on my pi zero 2 literally yesterday, still tuning it lol

You do great videos. Super informative and right on the point. Keep it up. Thank you for your support for the community. I'm thinking of using Klipper on my ender 3 v2. Before I try it I have couple questions. 1. After I flash Klipper on my Ender, if I don't like it can I flash back to Marlin? 2. I'm planning on adding a dual z stepper motors. Does Klipper support Z align function? If it does what mainboard do you recommend I should buy with at least 5 stepper drivers for the ender 3 v2? I'm a little net to tinkering 3D printers. If you could help I would greatly appreciate it.

I literally just finished putting mainsail and klipper on the rasp pi zero 2 through uart last night

I will be getting one to use on a DIY prusa mini that i wanted to klipperize anyways :)

Thanks for another great video. You say it runs all these no problem. What happens if you throw an hdmi display and a camera on mainsail? Could it handle it or is there a display type that works on Klipper screen that’s less taxing?

Snagged 2 from digikey nov 10 hope to try out on my v0.1 build

Thanks for the testing and for answering all these questions most of would ask before buying. Update: It's already out of stock everywhere here in Sweden :(

Defo be dope for a bonsai build!

This board almost perfect. Except you can't buy one. Almost all of international shipping online stores - either have it out of stock, or pricing it at $40+ instead of $15.

My Pi Zero 2 is running Klipper + fluidd connected to an Ender 3 V2. Doesn't get much better IMO. Great setup.

I love the sketchy ERCF filament feeder patch behind you.

Can you use an ice tower with this It might help with the cores getting taxed?

Cool stuff. Your arms are all over the place.

I bought two for 32 Euros on launch day here in Portugal with physical store pickup (Mauser). One is running Klipper+Mainsail, the other Marlin+Octoprint. They run great, not much of a difference to my single Pi3B+, to be honest. Only my Pi4's are noticeably faster, as expected.

Does it have enough capacity for a 7 "touch and printer with a clipper and a cam?

Just looking for a cheaper alternative to run klipper. THANKS

Using a raspberry Pi cam as a webcam, then use an endoscope cam on the free USB micro port

Itd be cool for someone to make a hat with extra usb ports and screen ribbon cable port. It'd keep the footprint small. Have ribbon on the hat for the hdmi port make that work for the screen ribbon port and a ribbon mini USB to make it compact

Nice vid. Thanks. 2 questions: 1. Would this be better for the V0.1? And 2. "To like that smash button"? Hehe

Can someone explain what the "input shaper" is or link to it please?

Just used one to convert my Ender 3 to Klipper, and will definitely use one on the legacy I'm building!!

Psychic Nero!

Would the zero or a 2b pi work well as a secondary MCU to control accessories? Such as input shaping, LED lights, temp probes, and in the future heated enclosure control.

I lucked out and found 2 yesterday. I'm going to use one for Klipper on my heavily modified Ender 3 V2.

Is it possible to connect an MKS Gen L v1 trhough UART mode to the raspberry?

I have an 8 year-old full size RPI 2 model B, laying around. Do you think that will still work with the setup?

Did you have any issues installing clipper onto it? I got up to the point when I have to install the USB USB and when i SSH into the pi it says that there is no such directory..

Fantastic content. Have you seen the video about running Octoprint off an old android phone? That covers screen and camera in a neat package. Yes it's not low powered or discreet but it is a good camera (depending on the phone used). Great video. Keep up the good work.

if I am using the pi zero w 2 powered by the gpio pins from one of your videos. I am having a issue with it connecting to the printer. I am thinking it has to do with the MCU and serial usb connection thing. being how now I am using gpio so no usb address. or am I not looking at this corectly. I had this running with a pi4 but I can't get it to connect with the zero2.

With octoprint have problem with precompilation config file , serial number always error

HI! ONLY ME HAVE THE PROBLEM THAT WHEN I DO AN EMERGENCY SHUTDOWN THE PI DOES NOT RESET? I HAVE TO TURN IT OFF AND ON TO GET IT RECONNECTED .... ANY IDEA TO FIX IT?

For a beginner would you recommend octoprint or klipper? Does klipper require a log in like octoprint? My primary goal is just wireless capability, I have far too many accounts as is and I find it extremely unfortunate that octoprint will not operate with out a login even on a local network. I understand the cases where you want to access your printer at work or on vacation, however I am just looking to get away from usb and sd for a cleaner more streamlined experience. Is klipper the solution I am looking for? Thanks in advance!

Please keep in mind, if you’re running a webcam and a screen and usb hub, powering it thru 5V pin from the printer board, may be too much current for the printer mainboards regulator.

Hey. Someone connected rpi zero 2w with skr mini e3 v3.0 via uart? No communication between mainsail and kipper.

I´m a little stuck regarding the PWR connection of the Pi. Many use a Buck converter, but I would like to directly connect it to the SKR mini E3 V2.0 board i have. There are at least two 5V pins. One is from the actual Display (which may not be used anymore) and the other one on SPI, but nowhere on the web I can find an answer to weather i can use these pins to power a RPi Zero or 3 A+ or not. I need 2.4A output.. But not even BTT specifies that information. Can anyone help?

lol i bought 2 of em while watching this video!

Does anyone has experience with klipperscreen on a zero 2 w? Can it run flawless?

We have at least 1 report of fragging of BTT SKR MINI E3 V2 using this method (issue 665 on BTT github site, search on "dead" or "kilpper" (sic)). Do we know what current you can draw on the "serial" pins? Is the RPI Zero 2 W just the wrong too power hungry?

I will use it for my V0 build. You power up and get your serial connetion over the pin header? Is there some dokumentation how to do this?

Thanks Nero! What mainboard board did you test powering the pi from 5V? I'm going to try powering it from 5V on a MKS Robin Nano V2 board. I see the pi's max current draw under load is 500mA. My quick review of the 5V step down chip in the MKS shows it can handle 3A. But I have no idea if any other components in the step down circuitry need to be spec'd to handle higher current.

$60 here in Australia. I paid $90 for my pi4.

Actually I already used the original Pi Zero on my Prusa mk3s+ - without cam of course. The mk3 had an internal port for the Pi zero sice it was released. So the Pi Zero 2 is a great upgrade, as you now can just swap out the Pi Z, insert Pi Z 2, connect a Pi camera and can install Klipper (with Input shaper). So it is a great upgrade for a very low price. On the other hand, with spring steel management, filament autoload and optional MMU2 support on the mk3s+ I am still not totaly sure how to keep this features with Klipper, so I might only try it on one of my 4 Prusas now. I would realy like a video how to do this features (esp. Filament Autoload and MMU2) on Klipper. But I am quite sure someone will do an ready to use Image for the mk3s soon anyway. It is a very common printer and mostly used stock (or with Bondtech upgrade, or as Bear or Zarribo), so not to many variations ot there. The zero 2 might make Klipper beginner friendly for users not wanting to tinker with their Prusa but simply use them to print, as a Klipper upgrade can be plug and play on theese maschines.

is there a good video explaining arc welder?

My neck of the woods a Pi 3b + is close to 120 USD so even when factoring all the extra stuff you need to run a Pi 0 2 W it does not even come close to the more expensive option.

I can find desktop PC's here in romania that are cheaper than raspberry pi zero 2. The scalpers or whatever, done a great job at boosting the price of a RPI zero 2 at more than 100 euros....

If the Pi is getting power from the printer board, doesn't it possibly corrupt the sd card when the printer is turned off without shutting the Pi down properly?

Got one shipped for 24€, I'll use it to remove my 4 from the printer and use it for something else

His mustache looks like a pair of angel wings

Would you power a Pi Zero 2 off of an SKR 1.3?

Wish it had 1GB. Micro SD cards fail after so many read/writes. More ram means more caching and less IO and will go easier on the SD card.

where can we buy this tho?

Can the pi zero 2 be powered through gpio?

What do you mean by "unfortunately, I live in Canada", eh?

Did you have any issues getting Numpy installed on your Pi Zero 2?

if they werent being resold for $90 i would get one

Pi Zero 2W... built in wifi... what is not to love!

current price on amazon is 120$ 😞

usb gpio hat + waveshare hat gpio screen - and you got screen and many usb's.

apparently this is supposed to be a $15 board, right? It is $77 on amazon ;-;

Raspberry Pi shipping costs are absurd in today's free, fast shipping climate.

What’s a smash button and how does one “like it”? Sounds kinky

I've really had great success with the PiZero2 running octoprint. But keep in mind that the pi will struggle to stream 1080p video (tested with Picam V1.3, 2.0 and Camera Model B rev 2.0), even if you overclock the GPU to 600Mhz, while my Pi4 has no problem doing so. I don't think this is a large downside since the picams have the larges Fov at around 720p, but you need to consider this so you wont be disappointed.

Problem is buying a Raspberry Pi these days.

Rip. Last Pi's have been purchased

ive tested along side the other rpis the w2 sucks; get an rpi4 or 400

$60 here in Australia. I paid $90 for my pi4.

So I can take a flash card with the installed system with the raspberry pi zero, put in the raspberry pi zero 2 and will it work from the box? Or need reinstall firmware?
