Nmark GCL Hardware Manual

Chapter 1: Introduction

Aerotech's Nmark GCL, part of the A3200 product family, is a closed-loop scanner module that allows direct
control of galvo scanner servo motion for marking parts of unlimited size and complexity. The Nmark GCL
has support for CO2 and YAG lasers and includes Position Synchronized Output (PSO) laser firing based on
real-time scanner positional feedback. This allows the marking of large features with continuous motion of
the servo axis and simultaneous marking by the scanner.
