Raspberry Pi Zero W not showing boot activity via LED
(crossposting from https://manual.prusa3d.com/Answers/View/1736/Raspberry+Pi+Zero+W+not+showing+boot+activity+via+LED )
I’ve got my Pi plugged into the EINSY board, all the pins are going through, and the rPi port is turned on in Settings, but I’m not seeing any boot activity through the Pi’s activity LED (and it’s not connecting to WiFi or anything like that).
I tested the power pins with a multimeter, and 5V power does appear to be running through them, and the system does boot when plugged into a USB power source: what could be going wrong?

Does it run by itself with a stock boot image?

I'm afraid you may have attached the header to the wrong side of the Pi. Take a look at the photos in step 7 of the tutorial here: https://manual.prusa3d.com/Guide/0.+Preparing+necessary+components/585?lang=en .

You definetly used the wrong side.
An please make sure that your soldering is ok.
In your Picture it seems that your soldering is some kind of "sticking" but not properly soldered.
You have to excuse my english (i´m german) when it is getting that technical.
