Костомный принтер с 2Y 2Z

День добрый господа, задался идеей собрать (и уже собран) машину с осями 1х 2Y 2Z, на основе M8P. Но пришло время писать конфиг и тут я в ступоре, кинематики с 2мя Z есть, а вот с Y засада, ругается и все тут... 

Option 'step_pin' is not valid in section 'stepper_y2'

Once the underlying issue is corrected, use the "RESTART"

command to reload the config and restart the host software.

Printer is halted.

я совсем не спец, есть такие? кто разберется или уведет ошибку ???
