Before turn on machine, please check the position of lens carriage. If the bottom of
lens carriage is too low, it may hit the edge of working table or cutting bar and crash
machine. Sometime, carriage badly, the x- y axis will be twisted a little and affect
engraving/cutting quality. .......................................................................................... 25

Introduction
This maintenance manual provides a component overview for the LaserPro T500 and
instructions for replacing and maintaining the components of the machine. It also
includes a troubleshooting chapter with some handy hints when problems arise or if the
machine does not operate properly.

Component Overview
The following diagrams represent all of the maintainable mechanical and electronic
components of the machine, and their parts lists for convenient parts replacement.
The LaserPro T500 includes six main units as follows. Each unit will be discussed in depth
in later chapters.

Motion System Assembly

The Motion System is driven by servomotors, which includes X and Y motors. The X motor sits at
the right hand side of the X-rail, and moves the lens carriage left and right via the X-axis belt, while
the Y motor moves the X-rail in a forward and backward motion simultaneously using two Y-axis
belts at either end.
The motion system provides an exact positioning and coordination guiding the laser beam to
engrave the material at the designated target location on the work piece. The laser beam comes
from the laser tube, and is reflected by adjustable mirrors to pass through a focal lens that focuses
the energy.
There are three reflective mirrors within the motion system. Mirror 2 is situated at the top left
corner of the motion frame, and receives and reflects the laser beam to mirror 3 that sits on the left
side of the X-rail. After passing through Mirror 3, the laser is reflected to mirror 4, which is fixed
above the focal lens of the lens carriage. Once reflected through Mirror 4, the beam is focused
through the focal lens onto the work piece.

5 Component Overview
Lens Carriage Assembly
The lens carriage consists of a mirror (Mirror 4) and lens. Mirror 4 reflects the beam through the
focal lens that focuses the beam onto the material. In general, a 4.0-inch lens is included as standard
with the machine. However, there is also a 2.0-inch lens available.
For the detail components and parts numbers of lens carriage, please see the Mechanical Diagram
section.

X Motor Unit Assembly
The X-motor unit is located at the right side of the machine. X motor PCB has two sensors that can
sense the x and y margin when the lens carriage moves toward it. hen the lens carriage’s detector
detects the sensor, the lens carriage will then move in a diagonal direction to the original point
(back left corner of the machine).
