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.
