1. Introduction
1.1 General Information
This manual is the designated user guide for the installation, setup, safe operation, and maintenance of your cabinet
laser engraver. It is divided into six chapters covering general information, safety instructions, installation steps,
operation instructions, maintenance procedures, and contact information.
ALL personnel involved in the installation, setup, operation, maintenance, and repair of this machine should read
and understand this manual, particularly its safety instructions. Some components are extremely high voltage
and/or produce powerful laser radiation. Substandard performance and longevity, property damage, and personal
injury may result from not knowing and following these instructions.
Your laser engraver works by emitting a powerful laser beam from a glass tube filled with excited carbon dioxide
(CO₂), reflecting that beam off three mirrors and through a focus lens, and using this focused light to etch designs into
certain substrates. The first mirror is fixed near the end of the laser tube, the second mirror travels along the machine's
Y axis, and the third mirror is attached to the laser head that travels along the X axis. Because some dust from the
engraving process settles on the mirrors, they require frequent cleaning. Because they move during operation, they
also require periodic readjustment using their attached positioning screws to maintain the proper laser path. A water
cooling system—typically a pump or chiller—must be used with this engraver to dissipate the heat produced by the
laser tube. Similarly, an exhaust system—typically either an external vent or a dedicated air purifier—must be used
to remove the dust and gases produced by the engraving process.
With low intensity use, the provided laser tube has an average lifespan around 12000 hours before requiring
replacement. However, constantly running your laser above 70% of its maximum rated power can significantly
shorten its service life. It is recommended to use settings from 10–70% of the maximum rated power to enjoy optimal
performance and longevity.
Note that this is a high-voltage device and, as a safety precaution, it is recommended to only touch its components
with one hand at a time during use.
Note that the active laser is invisible to the human eye. This device should never be used while any cover is open to
avoid potentially permanent injury.
Note also that the water cooling system and exhaust system are both absolutely essential to the safe use of this device.
Never operate the engraver without both of these systems operating properly. Water should always be kept clean and
around room temperature, and the exhaust system should always comply with all applicable laws and regulations for
workplace and environmental air quality.
