OctoPi works, but not when plugged into MK3S
I populated a Raspberry Pi with header pins on 3,5,7,9,15 and 16 as indicated in the knowledge base page, and flashed a card with the modified OctoPi image. When out of the Prusa and powered by the USB port, it works, that is, I can browse to the web server and upload gcode to it.
When plugged into the printer, however, with the printed adapter below it, the power light does not come on and it does not connect to the network. the six listed pins are all SCL, SDA, CLK and ground. What powers the Pi when it is plugged in? RPi port is enabled.
RE: OctoPi works, but not when plugged into MK3S
Depends on the Pi model - the only one that can be safely powered from the Einsy is the Zero. The rest - and ABSOLUTELY the 4 - need a separate power supply.
Is your printer grinding? Bearings squeaking? Motors smoking?

wait...those pins do not sound right. but I'm mobile........I think you're on the wrong side of the pin header. please triple check your pinout

It's a zero w.
RE: OctoPi works, but not when plugged into MK3S
My suggestion is you freeze immediately....and verify the pins you are using and the instructions you are following. I'm 99% sure the UART is pins 8 and 10 with ground on 6. I think you're on the wrong side of the header. Be careful!!!!

Yes, I had placed pins with board components on outside. I moved them, and all works now. Thanks for your help.

Although Pi zero is most definitely not recommended for OctoPrint, I thought the advantage of the zero was that it plugged directly into the mainboard.

The Zero works fine as long as you don't use a pi- or webcam to stream videos or other USB devices. Use it only for data exchange. Here the Prusa manual:

The Zero takes longer to boot than the RPi3 used with my Ender3, but works fine when loaded. I am not using a webcam. A couple of other questions about the Prusa fork of OctoPrint:
1. Does power panic work now with OctoPrint, or only when printing directly from the SD card?
2. Can Prusa Octoprint be updated from within the app, or only when Prusa releases an updated version?
Loving my MK3S; will likely sell the Ender3 on ebay.

My i3MK3s and the Zero W with a regular Pi-cam work great since about a year now. It´s not a perfectly smooth stream but good enough to check on the printer two decks down and there is no negative impact on print quality.

take a look thru my repo here: https://github.com/itcarsales/prusaPi
there is also a link to foosel's guide and some more info on OctoPi vs OctoPrint....but using either will cost you some Prusa features.

Oh, btw, the Pi port needs to be powered on in the Prusa settings ...

Here is an easy solution for the filament sensor: https://www.prusaprinters.org/prints/25728-prusa-mk3s-ir-sensor-spacer-set
As far as the Pi Zero goes, that's like getting mad at Dell because your $500 PC won't play the latest video games at the highest settings. If you want OctoPrint control, monitoring, plugins, AND video, the zero was never intended to have the power to do it all. Even a 3b+ can still be easily overtaxed and cause micro stutters and missed steps with enough load. Personally, I find the available interfaces and ability to make modifications the singular BEST design aspect of Prusa units!!

I rank the Pi Zero W and filament sensor among the least successful design aspects off the myloweslife Mk3 .
Great!
