OctoPrint on Ender 3 V3 SE

Technically there is no "OctoPrint on Ender 3 V3 SE" as you won't be installing any firmware. All it takes is to install OctoPrint on a computer connected by USB-C cable to the printer and you're set for the most part.

OctoPrint will communicate with stock Marlin firmware providing remote controls, job monitoring, telegram notifications and much more with a good number of available plugins. I've heard it can be even installed on mobile phone connected to printer yet I have not tested this.

Installation and configuration

1. Get a PC/RPi/whatever capable of running debian type system and prep it until you're SSH'ed into.

2. Get KIAUH and install Octoprint.

Yeah, that's it. Rest of the configuration is done via webUI which defaults to your-controller-ip:5000.

Alternatively you can use dedicated OctoPi OS by following these instructions.
