    Bridgeport CNC

    I was thinking of converting my Bridgeport series II over to servo motors using this kit from Keling
    : 3 PCS KL34-180-90 (NEMA 34) Dual Shaft, 1125 oz-in Peak
    90V/40A
    I am concerned about the torgue of these motors compared to the original steppers and also the mounting difference between Nema 42 and Nema 34I also believe the original steppers are running a 2-1 reduction.
    I would prefer to use my original pulleys and belts.
    Anyone been down this road?
