[Swansea Hackspace] Arduino Uno interface to a 3D printer stepper motor.

[oliver Oliver]

Think about pulleys or gears.  I don't know if you want the pole to stop at
a particular point or not.  Inertia in 1m pole will be higher than braking
force of a stepper motor.  So it will continue to spin after you stop the
motor. Giving you an unpredictable 180 plus rotation.

For a pulley arrangement look at t5  timing belts.  you can easily print
the pulleys using a reprap.  There are libraries on thingiverse.

A worm gear would be better,  but you can't print those.
