    second question I have is..
    with me using the heds encoder and plugging that into the dc servo drive as the manual instructs,
    is the optical sensor that sits on top of the spindle and the tach no longer required??

    I don't understand why I would need 3 forms of feedback yet they were all installed as standard when the lathe was in its original state.
