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
So I add that as an include from another config. It’s saved me from a few complete failures 😁. For this I was trying to keep it as a basic config for others to use as a good base and I would like to submit a PR, eventually, to include it in klipper’s example configs.
