SAME. No one tells you about the M420 command. Worse of all, the original Ender 3 does not have a config EEPROM so it saves the settings on the SD card. Sometimes I’m not 100% sure if the bed mesh is even saved/loaded. Klipper took away all the doubt. Too bad RPi4 are still so hard to find or I would tell all my friends to change to Klipper.
