    i have to questions to ask:

    1.anybody has an idea about using 12v stepper motor for x and y axis,, and 24v stepper motor for x axis for their power? is it possible?

    2. is it possible also to use a combination of unipolar and bipolar stepper motor for my x, y, and z axis?

    The amount of motion will depend uppon Step/Direction commands and the number of steps per rev of the motor, as well as whether the stepper driver is a micro-step or full step configuration. The voltage per axis would make no difference as long as the stepper driver matches the motor. Others may have different thoughts.

    Yes.

    Can you make that part more clear?

    Yes. Absolutely.

    Here's an interesting read:

    With chopper drive you can mix different voltage stepper motors using a single higher voltage supply provided it has adequate current.
    It can improve stepper motor performance.

    People have already said YES.

    The controller produces a STEP and DIR signal for each stepper motor driver.

    After that you can connect any 3 stepper motor drivers you like, and any 3 motors, running from any 3 voltages.

    It will all work fine as long as the stepper motor drivers accept standard logic-level STEP and DIR wires.
