Since the SmoothStepper outputs 5V signals (with currents limited to 24 or 32 mA, dependent on the selected output pin), you will need a motor driver between the SmoothStepper and the motor itself. For your axes (X, Y, Z, A, B, and C), the SmoothSteppers can control stepper motor drivers and digital servo motor drivers. The board does not support analog servo motor drivers or PWM servo motor drivers.

(Your computer should already have drivers installed for your Ethernet Card.)
|*SmoothStepper Motor signal outputs are only 5V and 24 mA or 32 mA. This will not drive a Stepper Motor directly, and you will need a Motor Driver for each stepper motor.
Digital Servo Motors typically have a motor driver built into their controller.
For a Spindle that is controlled by a 0V to 10V Analog signal, you will need a Break Out Board that can convert a PWM, Step/Dir, CW/CCW or Quadrature signals into a 0V to 10V analog signal (and also provide one or two relays to control the VFD).
