Feature:1. Laser Engraving: The N40630 engraving module with 5.5W output power can cut 3mm thick plywood at one time, with for NEJE or for Plus, the engraving speed can get to 1000mm/s.2. Extensive Using: Also has excellent compatibility with other engraving machines, 3D printers and CNC router machines. To be compatible with other CNC equipment, the engraving module must correspond to 3.312V voltage, 1%~100% duty cycle, and 020kHzfrequency.3. Safe in Working: Built in protective glass will make you feel more comfortable and safe while engraving, which will also enables easier operation.4. Smart Adjusting: Built in fast intelligent drive, timely temperature detection, intelligent adjustment of the fan to reduce noise, safe and quiet engraving work.5. Broader Utility: Can engrave wood, MDF, leather, paper, cotton, etc. Stainless steel, glass, transparent acrylic and so on.Specification:Item Type: Laser Engraving ModuleItem Model Number: N40630Module Input Power: 20-30WOptical Power Output: 5.5WWavelength: 440nmBeam Shape: Dot, focusable.

Please wear laser goggles when using to avoid direct contact with the eyes and skin of the laser. 2. Do not engrave mirror objects, pay attention to fire prevention and pets when working. 3. Smoke will be produced when burning, please pay attention to indoor smoke exhaust. 4. The warranty period of the laser module is one year. If you have any quality problems (except for individual cases, such as using the laser module for more than 30 minutes each time and causing damage), please feel free to ask our customer service for help. 5. If there is any problem with your laser module, please do not disassemble it without our permission, which will destroy the laser module. 6. If you have any quality problems with the machine, please feel free to contact us. Many operational issues can be resolved based on your video and problem description. 7. This laser module is compatible with our for NEJE Master 2 Plus and for Master 2 machines.8. It can also be compatible with other CNC equipment, such as 3D printers, CNC milling machines, etc., but requires a certain knowledge of PWM waveform control.
