Errors:
LCD_BED_LEVELING requires a programmable LCD controller.
I am getting an LCD_BED_LEVELING requires a programmable LCD controller error msg when I try to upload for a Ender3 v2 with mesh bed leveling and LCD_BED_LEVELING options set.
This is correct.
Currently, the Ender 3 V2 LCD screen does not support the displays required to use the LCD_BED_LEVELING option.
There are works underway to offer two options long term.
