The Gecko 320 and 340 drives are for servo motors.

You should start with a DC motor that is reversible, and has smooth rotation
at low speeds. (Try it with a single D cell, for instance). There are some
DC motors that are not suitable for servo work, as they have too much
torque or velocity ripple at low speeds.
