    Re: Chinese Stepper Driver - ZK-SMC02

    Have you tried setting F01 to P04. F06 should be set to 1, and F02 set to the number of steps to move.

    p.s. How do you measure the amps when changing the potentiometer on the bottom?

    Re: How to Cut Gears with CNC

    CA glue and painters tape works much better than double sided tape. Cut the center hole (or other opening) in the gear first and add a safety screw if you don't feel confident with the CA glue.

    Re: Rails or Rods on 12" x 42" bed

    Definitely use supported rods. You can also use self leveling epoxy to get it perfectly (within tolerances :halloween) flat. There are quite a few threads on it.
