COMGO Z1 Laser Engraver supports the most popular engraving software LaserGRBL.
LaserGRBL is an open source, easy to use and powerful software, but LaserGRBL only sup-
ports Windows (Win XP/Win 7/ Win 8/XP/ Win 10).
For Mac users, you can choose LightBurn, which is also an excellent engraving software, but
this costs $40 (with a free one-month trial for the first installation) and this software also
supports Windows systems.
The COMGO Z1 Laser Engraver receives mobile commands from the computer in real time,
and the engraver needs to stay connected to the computer and cannot close the engraving
software (LaserGRBL or LightBurn) during the engraving process. In addition, the configura-
tion of the computer can affect the speed and even the quality of the engraving. The
following will focus on the installation and use of LaserGRBL software. lightBurn will briefly
explain the installation and configuration process.

"Never Sleep" mode.
