That's interesting - I wonder why it is stated as a linear distance
rather than a degree of rotation?. If it stays constant then it
suggests a big diameter pulley will suffer much less backlash than a
smaller one, and given that the pulley is driving a leadscrew it's
the rotational backlash we are interested in.
