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 supports
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 configuration 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.
