Настройка MKS_GEN_L V1.0

Купил новый "MKS GEN_L V1.0" и пытаюсь настроить его с помощью Marlin 1.1.X. Я изменил configuration.h с предыдущей:

#define BOARD_RAMPS_13_EFB 33 //RAMPS 1.3 (Выходы питания:Hotend,Вентилятор,Стол)

Для

#define BOARD_MKS_GEN_L 53 //MKS GEN L.

Я получаю эту ошибку:

pins.h:268: error: #error "**Unknown MOTHERBOARD value set in Configuration.h**"
