Raspberry Pi Zero 2

Hi all,

Heads up. There's a new Raspberry Pi Zero out. The first review on Wired insinuates it's faster then a Pi 3 which I'm currently using for Octoprint.

I've purchased the Zero 2 and plan to install it on the main board.

I'll update you on my progress 

Kev

Job Done...

Hi all,

The Pi Zero 2 arrived and to be honest it was a really straight forward install.  I purchased some 20mm header pins from Amazon.  Prusa says 18mm but 20mm has worked perfectly.

Do not download OctoPi from GitHub as it's very out of date.  Use the link from octoprint.org to get OctoPi 0.18.0 with OctoPrint 1.7.0.

I backed up OctoPrint on my Pi 3 in advance and restored the config as part of the initial setup.  Previously the i3 was connected via USB so I had to follow the below guide to connect via the GPIO serial ports.

https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-user-mods-octoprint-enclosures-nozzles/rpi-zero-octopi-working/

That's it.  It's not as fast as my Pi 3 but that was also running from SSD over USB instead of SDCard.  But it isn't slow by any means.

I now have a spare Pi 3 with SSD and a much cleaner printer setup using the Pi Zero 2 🙂

Great news...

and... Foosel has confirmed that OctoPrint runs just fine on it and she has declared it officially compatible!

Considering replacing my Pi3 for the Pi Zero W 2, but have gotten used to having the CAM to view. Is the Pi Zero W 2 able to run a camera as well?

works but...

also installed the zero 2, it works really well and fast but it overheats without cooling!

 

now im looking for a new back encloser with 40mm mount. 5v you can get direct from zero

UK has stock

I ordered from the UK, no problems finding stock (perhaps because they only allow ordering one). Not sure how condusive they are to international shipping addresses, but not a problem for me.

RE: Raspberry Pi Zero 2

I want to run one of these with my MK3s+MMU2S.  I want to power it by USB and also connect via USB-B so I don't have to worry about powering the printer off.  My issue is finding a suitable cable to connect the Pi to the printer with.  Anyone found one?

Vilros had them in stock for a while last week and I jumped on it.  Still has yet to arrive.

IIRC they are limiting to one per household per month.

The one very recent Pi issue that some are reporting are various things with the new 'Bullseye' release of the OS, which is now replacing the 'Buster' release.  In particular many camera applications totally barf on the new Bullseye release.  They are apparently working on work-arounds.

RE: Raspberry Pi Zero 2

What's the story with the camera? Is this only with the Zero-2? Reason I'm asking is cuz my current big project is a full scale working model of a classic Leica camera and I want to use the Zero-2 and the new hi res camera in it. 

In that other thread the silver knob I've been having trouble with is for this. I sure hope I haven't painted myself into a corner on this!

I haven't been able to find the Zero-2 in stock yet but I'm on the list from Adafruit and a couple others when it's available.

RE: Raspberry Pi Zero 2

IIAC, those camera issues ONLY affect units that use the Latest And Greatest 'Bullseye' release of the OS, on ANY pi, and are not related to the Pi Zero 2w specifically.

The work-around, if you can even call it that, is to use or continue to use the last-generation 'Buster' release of the OS until they get things sorted out.

They are transitioning to the Linux libcamera library for camera support in lieu of the Pi-specific camera stack.  More information here:

https://www.raspberrypi.com/documentation/accessories/camera.html    and here:

https://www.raspberrypi.com/news/bullseye-camera-system/

So, you can either use the Latest And Greatest and put up with some bumps in the road, or the legacy applications, which are known to be stable and robust.

And if anyone is scoffing at the idea of using a Pi for some semi-serious photography, a few years ago I made a time-lapse spy camera from plans that were being passed around at our local makerspace and I was impressed with the quality of the photos.  This was using a legacy Pi Zero and the first-generation Pi Cam (5mp, IIRC) and in good light the photos are indeed very good.

It just uses a script to execute raspistill every so many seconds.

With the new 'HQ' camera, 12mp, they should be extremely good.

And, those who are observant may notice that the texture of the case is not that from a Prusa.  This was done long before I got my own printer, using the (now retired, I understand) Uprint at the local makerspace.
