This is what ACMER says: Super power: real 33W optical power laser engraving machine, using the latest 6W laser coupling technology, ultra-fine laser focus 0.08mm, minimum engraving accuracy 0.01mm, engraving speed can be as high as 24000mm/min, strong cutting capacity, can cut 30mm wood board, 20mm acrylic, and even cut 0.1mm stainless steel plate at one time. High efficiency: compared with 10W laser engraving machine, the cutting speed is increased by 200% and the cutting depth is increased by 150%. Compared with 20W laser engraving machine, the cutting speed is increased by 50%, and the cutting depth is increased by 25%. ACMER P2 33W is equipped with ESP32 dual processor chip. Built-in 256-bit color scale to achieve finer engraving effect and higher contrast effect. Larger engraving area and more engraving materials: 420 * 400mm large engraving area, can be engraved on wood, bamboo, paper, acrylic, leather, PCB board, aluminum oxide, metal, ceramics, etc.; can cut wood, acrylic, bamboo, leather, paper, etc., can DIY hundreds of materials. Solid structure, easy installation: ACMER P2 laser engraving machine adopts all-metal structure frame, which makes the machine more stable and durable and improves the engraving accuracy. The whole engraving machine adopts modular design, which is easy to assemble, maintain and update machine parts. 60% pre-assembly delivery, only 4 simple steps to install successfully, only 10-15 minutes to complete the installation of the whole equipment. Observable shield: Filtered glass shield protects your glasses and filters 97% of UV rays. Product standard with air-assist kit: significantly improve the cutting speed and cutting accuracy at the same time, improve the quality of the cut and avoid yellowing and burning of the material. Newly upgraded focusing system: with a new gate focusing design, more convenient and fast to complete the focus. Emergency stop button. When encountering an unexpected situation, the machine can be stopped at any time, making the carving work safer. 15 ° tilt angle protection function: the machine automatically stops working when tilted more than 15 °, to prevent the laser from tilting the machine to cause injury to the human body or damage objects, a good protection for your safety. Flame detection function: when the carving process too much smoke or fire, flame detection will start the alarm and stop the machine work. Emergency stop switch: When the machine is working, the machine can be stopped immediately by the emergency stop switch. Power safety lock: Each P2 is equipped with a safety key, which needs to be inserted to open the switch in order to work, preventing children or others from using your machine to cause accidental injury. Wide compatibility: This machine is compatible with various mature carving software and can be controlled by APP, such as LaserGRBL (free), LightBurn (paid), LaserGRBL supports Windows XP/7/8/10/11, LightBurn supports Mac OS and windows, carving file formats support NC, BMP and JPG, PNG, DXF, etc. Upgraded compressed spot coupling technology. Ultra-fine laser focus area is reduced to 0.08*0.1mm. Integrated design: 90% of the cables are hidden inside the machine, giving you a clean and tidy workbench. Industrial guide rail device: 20% more stable compared to other machines, ensuring stable operation and high precision engraving. Silent motor: All motors are made of silent motor for less noise and quiet operation.
