    Re: spindle encoder for lathe

    It all depends on which software and motion control vendor you are going to use. Some software (Mach3) only uses/reads one signal per revolution so all you need is a disk with one slot while others will read many signals/pulses per revolution.

    7xCNC - Minilathe CNC :: Spindle Encoder

    A simple photo interupter will give you an accurate spindle speed and the ability to cut threads.

    If you want a motor 'geared' off of an encoder as the way as it is done on professional systems.
    You need a Galil based, Linux, or dynomotion system.

    Yes it would. But, as I said, it depends on which software and motion controller you choose. Not all hardware and/or software combinations can utilize the information.

    That is what is used in the post #3 description.
