But for his purposes, a generic stepper motor controller that featured a potentiometer to adjust the speed was enough. He found a suitable board online for around $5 USD, and got to designing a 3D ...

As [Curious Scientist] demonstrates, this is a relatively simple motion control project ... a carriage up or down. An Arduino Nano acts as the brains, a stepper motor drives the lead screw ...

This specification is expressed in ounce-inches-seconds squared (oz-in-s 2), and is largely dependent on motor weight. Stepper motors are designed with characteristically low rotor inertia to allow ...
