    Default More power required.

    Here's a video of the stepper motor hooked up to my lathe, unfortunately, the motor simply doesn't have enough power.

    I wanted to hook a stepper up to the carriage, cross feed, compound and tailstock with an array of switches to allow me easy push button control to save my hands.

    Not to be, - yet. The premise works well because with a stepper I have precise control on stop and start plus I can still use the handles by hand if I were to use belt drive. Got to get a motor powerful enough first.

    If you don’t mind a slower rotation, how about a geared stepper?

    Slower is ideal actually trouble is most are worm drives which means manual rotation is not possible

    That one is a planetary gear set. Also, you can drive the motor at a higher voltage ( up to 45v I believe) and the TB6600 will handle the amps you set. Higher voltage will give greater torque according to articles on the web.

    power supply is the problem, that's why I opted for 12 volt, easy to come by. I do have 18 and 21 volt supplies but I think they are a little under power for this application, I'll give them a go though.

    Ran the stepper on 21 volt and 40 volts. lots of noise no go. I found 12 volt actually worked better. I think it's time to give this away, spent far too much time, effort and money - not to be. Now I have motors, controllers, generators all over the place and nothing to use them on.

    I agree with Lappa about the reduction drive, my table uses approx 22.5/1. I also found it essential to tune the motors to avoid stalling.
    Either that or a whopping motor.
