    Default VMC Hitachi Seiki VA 35 - Not rolling spindle

    After starting the machine and passing through reference points, the MDI does not execute command M 03 / M 04 / (which mean rolling respectively clockwise and counterclockwise) and M 19 / spindle orientation /. Also, the tool holder, which is situated in the spindle, can not be unlocked even though the hydraulic system works.
    Otherwise, the movements on the XYZ axes in the same MDI mode are executed.
    The management system is Fanuc 6M-B
    Year of production: 1986
    If someone has had a similar problem, please cooperate!

    I just bought the same machine, following this thread hope we can help each other. My spindle is working fine message me if you want to check out something on it. On mine the tool changing arm stuck in the lower position. Gonna need the recovery codes and the way to over ride the home position. It's in home but been restarted and wants to do home on all axis what we can not do as the z axis locked by the tool changer mechanism.
