In E.g.1, Pulse/rev is Pulses per revolution of stepper motor, so that the user only needs to
select a relative value according to the actual dial code. For example: If user choose 3200
Pulse/rev, indicates (360 °/stepper angle)* Driver subdivision=3200.
In E.g.2, the MSTEP means subdivision number. So, if the stepper angle is 1.8°, selected
subdivision is 16, then (360 °/stepper angle)* subdivision=(360°/1.8)*16=3200.
The use should use correct computational method according to the actual marks of
stepper motor driver nameplate.
Screw pitch (above picture): The distance that the nut moves when the ball screw makes
one rotation.
Transmission ratio: The reduction rate or angular velocity ratio of the front drive sprocket
to the end driven wheel.
Rack drive

Helical teeth:
Explain: Rack module and gear teeth number are both the parameters of the rack. Rack
module*gear teeth number*pi is the pitch circle
circumference of the rack.
