Three-Axis Stepper Motor Driver

Part 1: Design Basics

Technicians in high-tech laser laboratories use optical components such as lenses, mirrors, and filters to direct laser output. A multiple-axis stepper motor controller gives technicians greater control over the components. Special firmware enables remote control from a PC.
