I’ve got a RasPi 4 (4GB version). I never really put a whole lot of effort into it and just switch between SD cards as necessary.
Obviously, this is not a great solution. I was going to buy a Pi Zero 2 W for the OctoPrint so I could keep both services running simultaneously. But before I do that, I thought it would be cool if I could somehow put both services on my current device.
I’ve seen around this sub that people are running multiple services alongside Plex, but there’s not much talk about OctoPrint.
I would say, more than likely no. That being said, just try it and see. More than likely it’ll become apparent what is and isn’t usable (I’d guess the octoprint interface would become unbearable to navigate if you’re watching something at the same time).
You might also run into hangups on octoprint’s end, potentially halting prints, though I feel like that should be avoidable (I know I’ve had prints halt when my pi was undervolted)
