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 3.3‑12V voltage, 1%~100% duty cycle, and 0‑20kHzfrequency. 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.
