RPI Port dead? Raspberry Pi Zero 2W is not powered anymore
Hey all,
I have been using my Prusa MK3S+ with a Raspberry Pi Zero 2 W for a few months now without any issues.
Today out of a sudden first the Prusa Link indicated ,,RPI Port not enabled" on the Dashboard (although it was enabled). After a restart of the printer (power off) the raspberry pi does not even turn on anymore (the small led on the raspberry does not flash anymore). I have enabled the RPI port in the printer settings, I also did try to disable and enable it, no change. Also several restarts brought no change.
I checked the soldering, redid the soldering. I also checked to run the raspberry pi with a usb cable from my pc (it starts normally but obviously complains about a missing printer).
I am using the proposed printed cover for the raspberry. Now I am running out of ideas. I dont know whether the Raspberry Pi GPIOs have a problem (still bad soldering?) or the Rambo board. Is there a way I can test either of the two?
Thanks in advance!

Addon: I just checked with a multimeter that the voltage between the first two pins (which should be 5V and GND) from the top have 5V while the RPI is plugged in the RPI port.

Another addon: Apparently, I suck at soldering. I just did it again with lots of flux and now everything is working fine again. Probably one of the pins did not get a good connection, which broke after some time.
I guess I will mark the issue as solved. Hopefully it is at least useful for someone else encountering the same issue.
