BUYER MUST READING:

there are 2 Volltages (12V and 24V) for these lasers available, most CNC Engraver uses 12V, and some 3D printer is 24V, please chose the right one that fits your device when placing your order!

• Please pay attention when connecting wires : RED wire=12V+ /24V+ , BLACK wire=GND -, Yellow Wire= PWM+, White Wire= PWM- . !!! PWM and Laser share GND!!

• Wrong connection of the wires may damage the driver board and the diode

if your controller board’s laser interface pins are in different position, please change the wires position to make it match the positions of + – PWM of your interface. If the wires connected wrong, it will damage the diode and the driver board.

Frequency: <18khz, PWM/TTL: 0-5V

Please add a fan when engraving or cutting, in case smoke damage its lens
