-String up and measure z-axis alone.  First horizontal, with fishing line as belt.  Necessary to adjust bearing position to ease friction on z-travel.  Once that feels good, the plot below is obtained, moving in increments of 32*(1/32) steps eight times forward, then reversing.  Each full step is calculated, using the radius of the capstan, to be 0.31 mm.  Hysteresis is about 0.05 mm.
