    Newbie Question on Setup

    I have 10 - 24 lead screw, 200 step motors. If software/driver combo is microstepping at 1/8, does this look like 10 x 200 x 8 for the steps per rev?

    24 x 200 x 8

    The screw is smaller than 1/4", right?

    the screw is 10 - 24 all-thread. I guess your question indicates that I have the properties wrong on the screw... it's 24 turns per inch then? so I would set the params for steps per rev at 24 x 200 x 8 = 38400 ??

    thanks

    yes. If you measure 1" of the screw, you should count 24 thrads in that 1".
