CONNECTION DESCRIPTION

Please check whether the laser module is compatible with your engraving machine before connection.
A. Check the voltage parameter of you engraving machine.
Please ensure your engraving machine can provide at least 24V 4A power supply.
B. Check the port of the main control board on your engraving machine.
Please find the PWM port, GND port and VCC port on the main board of your engraving machine. Then connect this laser module to the main board accordingly.

“A” &”B” are both Compatible.

Connect the laser module to the main board of your engraving machine directly.

PRECAUTIONS

Laser may cause damage to your skin. Please do not expose your skin directly to the laser.
Please wear laser goggles to protect your eyes when you use this laser module.
Please ensure that the air pump is turned on before you start cutting. If not, the smoke will contaminate the lens.
This laser module doesn’t support hot plug, hot plug may cause damage  to the laser module.

 MAINTENANCE

When the laser module is not used for a long time, please ensure that the lens is not polluted by dust.
When you replace the air nozzle, please ensure that your operation will not pollut the lens. Finger prints or dust on the lens will weaken the output power of the laser module, or even damage the lens.
When you find the cutting ability decreases, the lens might be not clean.
Please use a clean alcohol swab to clean it according to the following figure.
