FAQ
I. Unable to power on the machine.
Ensure all outlets, switches, and power cables are plugged in and powered up properly. Try a different power
source or cable if necessary.
II. Unable to connect to computers.
1. USB cable not connected: Please make sure the data cable is correctly plugged. On some PCs, the front USB
port is not receiving enough power for the engraving machine. We recommend using the USB port at the
back for a stable connection.
2. The driver is not correctly installed: Install the driver according to the instructions again. After the installation
is done, your computer can recognize the machine as a serial port. You can find a serial COM port in the
computer's device manager.
3. If both solutions above are not working, try unplugging the USB cable and power cord, turn off the machine
for at least five seconds, then power it on and reconnect again.
III. Machine gives no response when controlling via the mobile phone application.
1. The wrong machine is connected: If you have multiple machines in the workspace, please make sure you
connect to the correct machine.
2. Compatibility Issue: Compatibility issues may occur when updating your phone to a new system version.
Please don't hesitate to contact us with your system information if that happens. We will add support for it as
soon as possible.
IV. The engraving looks blurry or shadowed.
1. Focus: Most commonly, the laser was not correctly focused before starting the job.
2. Engraving Speed: If you set the engraving speed too fast, the laser will have insufficient time to engrave
your workpiece. Please adjust your engraving settings and do the engraving again.
