Features(Manufacturer refurbished):
Solid And Easy Installation Structure Design:
All-aluminum alloy anodized structure design makes the machine more durable, and improves the accuracy of engraving. The entire machine structure can generally be completed within 10-20 minutes.
New Filter Eye conservation Acrylic Design:The filter acrylic protective cover plays a good role in protecting your eyes, filtering 97% of ultraviolet light, free to watch the laser engraving without goggles.
Upgraded High-Performance Fixed-Focus Laser:No need to adjust the focus before engraving and more stable than the zoom laser as well; The new laser focal spot is 50% smaller than other ordinary lasers, new laser combine precision engraving and high energy cutting at the same time.
Newly Upgraded Ultra-Fine Compression Laser: Adopts 4-fold lens group collimation and focus technology, the optical power is 5-5.5W, laser focus area is reduced to 0.08*0.08mm. The high-density laser can easily cut 20mm thick wooden boards, 15mm black acrylic; Directly engrave mirror stainless steel metal and ceramics, and can achieve the effect of a 100W CO₂ laser engraving machine. 
Precise Scale Lines Axis :There are precise scale lines on the X-axis and Y-axis to facilitate quick length measurement. 410x400mm large area engraving interval can meet your various engraving needs.
Wide Compatibility:The machine can be compatible with various mature engraving software, such as LaserGRBL, LightBurn, support Win XP / Win 7 / Win 8 / XP / Win 10, and also support MAC system (LightBurn), engraving file format supports NC, BMP, JPG, PNG, DXF etc.
More Function:Uses an integrated screw rod which makes the movement of the laser more precise and the coupling more durable. Support offline engraving; In the event of an unexpected situation, stop the machine at any time to make the engraving safer. The laser sintering temperature is up to 800~850℃.
