Features: 【Precision Scale Line Axis】: X-axis and Y-axis has precision scale lines, which is convenient for you to carry out quick length measurement. The 400x400mm large-area engraving interval can meet your various engraving needs. Widely used in metal(non-reflective or painted black), wood, plastic, paper, bamboo, leather, etc. 【Lightweight and Eye protection Design】: The laser engraver is equipped with a laser shielding sleeve to protect your eyes from injury,lightweight and convenient for assembly and disassembly. 【Intelligent Safety Protection System】: When the laser is in an abnormal state and continues to be irradiated, the laser will automatically stop to prevent fire; when the engraving machine is impacted by an external force, the laser will automatically stop to avoid danger (Customers can choose whether to use this function). 【Solid and Easy Installation Structure】: The full-metal structure design makes the machine more solid and durable, and improves the accuracy of engraving. The whole structure is designed for quick assembly, and the assembly can generally be completed within 15-20 minutes. 【Extensive Compatibility】: The machine can be compatible with various mature engraving software, such as LaserGRBL,LightBurn,Benbox and GrblController as well as systems Windows and MacOS. 【Ultra-Fine Compression Laser】: Laser output optical power is 4.5-5.5W, the high-power engraving is faster and more accurate. The ultra-fine laser precision is reduced to ± 0.01 mm. The high-density laser can directly engrave smooth stainless steel metal and ceramics. 【Upgraded Fixed-Focus Laser】: Engraving can be done without adjusting the focus; The laser can combine both precision engraving and high-energy cutting at the same time. The laser power of the fixed-focus laser is more stable than the zoom laser.
