If you install the Sangaboard library for python (wither on the pi, or another computer with python), by running:
pip install sangaboard
You should be able to check that this minimal example moves a motor:
from sangaboard import Sangaboard
with Sangaboard() as sb:
sb.move_rel([1000,0,0])
print(sb.position)
sb.move_rel([-1000,0,0])
We are having some issues with the Nano motor boards. @jc2450 is building one this week to do some debugging.
