Why many people use Pi ZeroW for Octoprint even Octoprint states that Pi Zero is not recommended?  

RE: Why many people use Pi ZeroW for Octoprint even Octoprint states that Pi Zero is not recommended?

".... how come?"  I suspect when the Mk3 mainboard was conceived the zero seemed like a good idea. I wonder is Joe asked Gina before he committed? Anyway things have moved on and the zero is no longer fit for task. Get a 3B+ or 4B (same price most places).

Thanks. There are many guides on how to use the Pi ZeroW with the Prusa i3 MK3. Any good guide on how to do it with the Pi 4? As for storage, what size of the SD card is recommended?

RE: Why many people use Pi ZeroW for Octoprint even Octoprint states that Pi Zero is not recommended?

The only reason to use the Zero would be to fit it into the Einsy case.  Very small benefit if you ask me.

I've been using the 16 gb Pi cards and haven't had any problem.  My pi is 14% used of the 16gb card. Videos recorded by OctoPrint would chew into that.

BTW don't get an 8GB Pi4, there is some issue either for Raspian or OctoPrint. I'd get either a 3B+ or 1 or 2GB 4B

Thanks. What is the use for video recording?

People like to 1) remotely check on the printer to make sure the job hasn't become a pile of spaghetti and 2) record cool build-up videos of the job print.

Both are able to be done with OctoPrint.

Being able to check remotely the printer to make sure that the job is working fine is important to me but isn't the camera viewing realtime? If that is the case, do I still it to record?

RE: Why many people use Pi ZeroW for Octoprint even Octoprint states that Pi Zero is not recommended?

You're right Peter but real time is actually more demanding that recording because most of the recording is just still frame time lapse.

When using the Pi4 with Octoprint and Pi camera, which Sandisk microSD card is recommended? The one with white and grey or red and gold on the surface?

Not to be short, but....    whatever ones you happen to have lying around or "I have never heard of any complaints on any."

But someone probably will have some.  You are NOT using a super high resolution DLSR camera in 8k video mode so consider that.

IIRC, Octoprint worked "well enough" on the original RPi B+ and the thinking when the Zero was announced was that the Zero was essentially the same capability in a smaller package. The realization that wireless and USB bus performance were in contention on the Zero W took a while. I suspect the Mk3 design team was a bit over-optimistic in terms of what the Zero W could handle and Octoprint's changing requirements in the last 3+ years.

I do agree that Prusa should label those pages as obsolete to avoid ongoing confusion. The Octoprint developer has specifically stated that the Zero W is not supported since 2017. Octoprint's requirements have also grown over time, and I notice that the recent recommendations are for a RPi 3B or greater. Even the 2B isn'trecommended any longer.

Of course, it would be awesome if a multi-core Zero  drop-in replacement, but this doesn't seem to be likely. This is why I'm baffled that Prusa elected to use the lowly EP01 module in the Mini.

And clarify what the hardware setting named "RPI Enabled" means.

It really means "Pi on internal Einsy USB port"  and if your Pi is connected to the external USB port then you want to set this LCD setting to NO.

I know there's very little memory available for firmware on the Mk3. I wonder what removing those RPi Einsy support routines would gain in memory for other features.

It's a shame. Reading up on the Mk3 back in late 2017, I was stoked about the RPi integration, but it didn't take long to realize it wasn't going to work out in the long term.
