One of the bigger problems with any CNC machine or 3D printer is the issue of missed steps when moving the toolhead. If a stepper motor misses a step, the entire layer of the print – and every layer ...

Our project focuses on improving the control system for an electric-vehicle motor, previously used in a racing competition by the UDA E-Team (short for Universidad del Azuay, Ecuador). This project ...

Here is how to implement a stepper motor to sense position and actively correct any error that might accrue during actuation.

Meet Charlie and Billy, the most adorable little robots in all the land. Billy, the first iteration, is a combination of 3D-printed parts, an Arduino Leonardo, and dual DC motors to form a hexapod ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...
