    Should be a bunch of these for sale used. I watched the upgrade video the other day for servos and looks pretty straight forward.

    going by the Tormach 770 schematic

    Attachment 419954

    the stepper motors have 3 phase windings - not the usual 2 phase motors

    (the NEMA motor number = frame size in inches ignoring the decimal point
    for example NEMA 17 = 1.7" square and NEMA 34 = 3.4" square )

    possibly driven by Tormach/Leadshine 3ND883m stepper drivers
