Octoprint is an excellent tool that allows you to use a device like Raspberry Pi to control your printer, but out of the box, its really only meant to be able to control one printer at a time. If you want to fully control multiple printers with a single device, you will need to have multiple Octoprint/OctoPi instances installed. In this video, I’m going to show you how to run multiple instances of the latest version of OctoPi (0.18 at the time of this recording) on a Rasberry Pi. I walk through the entire setup process and include tips/tricks along the way.
