не работает 2-й экструдер на mks-sbase smoothieware

Всем доброй ночи, пытаюсь подключить второй экструдер и ничего не получается((

я оставлял оригинальный, редактировал ручками, копировал первый (который работает) и вставлял, меняя hotend на hotend2 - ничего.

ставил разные firmware: китайский, оригинальный, оригинальные разные там в папочке их много...

если без шуток, я уже не помню, сколько всего перепробовал и что там за каша в конфиге.

стандартный возвращал, не подумайте, начинал сначала.

я в отчаянии.

может ,сталкивался кто, спасите!

вот выдержка из конфига:
