I was looking over this thread from almost a year ago. I see there, and in requirements for OctoPrint, that a Pi Zero is not enough to be sure things will work smoothly with OctoPrint. I see a Pi Zero W 2 is suggested as a possibility for OctoPrint.
Can that device handle both regular printing and a webcam that I use to check on progress and for timelapse videos? I'm going to be setting up several and going with a Zero over even a 3B or 3B+ would make a difference over several units, but it's not worth it if it would lead to printing issues.
