Reduce the cost of your goggles and the inconvenience of wearing goggles.7.Solid and easy installation structure design:The all-aluminum alloy anodized structure design makes the machine more durable, and improves the accuracy of engraving. The entire structure has been designed for quick assembly, and the assembly can generally be completed within 20-30 minutes.8. Upgraded high-performance fixed-focus laser: no need to adjust the focus before engraving;The focal spot area of the new laser is only 1/3 of the spot area of other ordinary lasers, new laser combine 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.9. 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.10.Precise scale lines axis :There are precise scale lines on the X-axis and Y-axis to facilitate quick length measurement. 400x400mm large area engraving interval can meet your various engraving needs.11. Upgraded compression spot coupling technology: ultra-fine laser focus area is reduced to 0.08*0.1mm, high-density laser can easily cut 25mm thick wood, 30mm thick black acrylic; can directly engrave mirror stainless steel metal, ceramics, glass, and engraving &The cutting speed is 40% higher than the ordinary model, which can be comparable to the effect of the 150W CO₂ laser engraving machine.12. Integral screw rod: The machine uses an integrated screw rod instead of a combined coupling. The stepping motor and the screw rod are integrated, which makes the movement of the laser more precise and the coupling more durable.13. New laser with knob: It is more convenient and quick to adjust the height of the laser.14. Support offline engraving: ATOMSTACK S20 PRO configures the terminal control panel, supports offline engraving, you can carry out engraving work anytime and anywhere without being restricted by the computer.16. The laser sintering temperature is up to 2400℃17. Emergency stop button: In the event of an unexpected situation, stop the machine at any time to make the engraving safer18. Stopper: Yes19. Reset switch: Yes20. Expandable engraving size: modular design of the body mechanism, only need to replace the frame components, you can get 400*850mm super large engraving size Please download the user manual settings/ installation manual /specification Sheet under the supports page or Download: S20 Pro User Manual ,S20 Pro Air Assist Kit User Manual, LaserGRBL Engraving Parameter Table , LightBurn Engraving Parameter TableProduct description:Item model number: ATOMSTACK S20 PROPrint Size: Recommend Print Size 400*400mmCarving Objects:Wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non-reflectiveElectroplating layer and paint surface layer metal, 304 mirror stainless steel, glass, ceramics, cotton cloth, slate;Cutting Objects:Cardboard, non-woven fabric, wood board, acrylic, some thin plastic board, sponge; Machine Power: 130WElectric power: 90WLaser output power: 20-21WWave Length: 445 ± 5nmEngraving accuracy: 0.01mmFocusing method: fixed focus laser, no need to focusLaser protective cover: Protect the user's eyes and prevent pets from grabbing the laser spot.Operating software: LaserGRBL, LightBurn, support Win XP / Win 7 / Win 8 / XP / Win 10 / Win 11 system.Input Format: NC, BMP, JPG, PNG, DXF, etc.Data transmission method: USB connection.Input Voltage: AC100-240V, 50/60HzOutput Voltage: DC12V, 5ACertification: CE FCC RoHS FDA PSES20 PRO LASER ENGRAVER PACKAGE:1 × Mounting screw1×Tool kit4×Foot pad foam1×Film3×Acrylic sheet3 × Wood chips10×Wire tie1×Desiccant1×Brush1×Clean cloth1×Card reader1×TF card1×Power adapter1×Instruction1×Data line1×Touch screen components1×HDMI cable1×Laser module1×Cutting pad1×X axis assembly1×Y axis left profile1×Y axis right profile1×Profile on the base1×Under the base profile3×Foot bracket Note:●When operating the laser engraving machine, please install the laser protective cover.
