(Actually its 1\/16.032 but for most purposes 1\/16 is a good enough approximation) What this means is that there are really 32*16.032 steps per revolution = 513 steps!

It also means you shouldn't use interleaved or micro-stepping to control or it will take forever to turn. Instead use single or double stepping.
