Chapter 1: Introduction
The GL4 is a closed-loop scanner module that lets you control servo motion from the galvo scanner to
mark parts with no limit to size and complexity. The GL4 supports CO2 and YAG lasers and includes
Position Synchronized Output (PSO) laser firing that uses real-time scanner positional feedback.
