I was using my pi for octoprint, worked so far until I tried to fit it into a custom pi case and now it doesn't work. I did have to squeeze it into the case but I can't see anything damaged on the pi.
I tried several microsd cards and nothing.
The power led is on but not the activity light. How can I tell what exactly is malfunctioning? Is it the micro sd card slot? The power plug? Something else??
