2. Introduction
2.1 General Information
Your laser engraver works by emitting a powerful laser beam from a glass tube filled with excited
carbon dioxide (
CO₂
), catalyzing nitrogen (N
₂
), and insulating helium (He), reflecting that beam off
three mirrors and through a focus lens, and using this focused light to cut and 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.
Laser Path
With low-intensity use, the provided laser tube has an average lifespan around 11,000 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. Further note at its rated voltage this device and its components
can draw over 30 amps at their maximum settings. Use separate 20A circuits for the machine’s two
power cords, prepare a robust dedicated circuit ahead of time, or carefully use lower settings to
avoid drawing too much power at one time.
