I have octoprint setup with instances running on it. I have 1 USB Logitech camera (that is working on port 8080. and then I have a raspberrypi camera. how do i get the raspiberrypi camera working on a different port?
Not really. I need to know where and what config file to edit.
You might check this thread.
Honestly, though, I would recommend just adding a Raspberry Pi Zero W with a Raspberry camera as an external webcam. The extra processing on your main Raspi can bog it down.
