Made sure the stock firmware printed the example gcode that came on the SD card and then immediately embarked on my journey to get klipper running on this guy.
I didn’t finish until the wee hours this morning so I’ve yet to really give it a go but all the essentials are operational.
Here’s the GitHub link to the config I created: https://github.com/0xD34D/ender3-v3-se-klipper-config
Klipper isn’t a web interface. Octoprint works with Klipper as a web interface. They’re different software for different things.
