3.Made of aluminum, strong and durable.4.Upgraded high quality fixed-focus laser, no need to focus.5. Aviation aluminum TTL driver board with cooling fan can ensure continuous long time work.6.Engravable materials: wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non-reflective electroplating layer and lacquered metal, after blackening Utility knife.7.Cutable material: cardboard, non-woven fabric, veneer, acrylic, some thin plastic board.8.0.08*0.15mm double compression spot light coupling technology makes engraving more powerful
and precise .9.Engraving speed is 200% higher than other 5W lasers.10.High energy can cut 8.5mm thickness plates at one time.11.The laser sintering temperature is 1100 degrees, the effect of engraving metal is better.12.The laser has a built-in horizontal gyroscope anti-tip protection device, and it stops working when the tilt angle is 20°.13.The wind-collecting hood can clean the smoke and dust to protect the lens to avoid laser energy attenuation.14.The transfer circuit board is compatible with 95% of laser engraving machines on the market，
Including Atomstack, ortur, Neje, twotree, etc.

2.Laser module needs an appropriate laser driver(PCB). When the laser module connects with power supply, please set the output voltage to zero. The adjustment of the current should be slowly increased or decrease to avoid damaging the device.
