If you are [Tech Build] you go all MacGyver on an old printer and pull out a stepper motor. How does a stepper motor turn into an encoder? Well, that’s the MacGyver part.

Fortunately, using stepper-motor driver chips, it is possible to design integrated electronic motor-driver circuits for these and similar applications that require only a few passive components.

At it’s heart, it’s a straightforward design, using a linear rail and a leadscrew driven by a stepper motor. Control is via an Arduino Nano, with a few push buttons and a 16 x 2 LCD display ...

Functionalities of the EPOS 2 motor speed, torque and position controller with multi-axis motherboard include: • Speed and position feed forward control. • PVT - Interpolated Position Mode. The ...
