Feature:1. CONVENIENT AND AUTOMATIC: The software directly parses .BMP, .JPG, .NC, .DXF files, and the software automatically connects, without manually searching for the port location2. MULTIPLE ALGORITHMS: The software includes 4 image algorithms, can provide a variety of grayscale algorithms and plain surface algorithms, and can perform 1:1 lossless3. EFFICIENT AND DURABLE: PWM control and temperature sensing, the maximum optimization of laser work efficiency and protection of laser life. With limit switch design, the machine can be reset automatically4. EASY TO USE: The whole machine is assembled and tested in the factory, after strict quality inspection, not a bunch of DIY parts, ready to use5. ADJUSTABLE PARAMETERS: The software can adjust the laser power and laser burning times, the actual adjustment is the engraving depth and speed6. POWER OFF MEMORY: After a pause you can check your workpiece and restart where left off, very convenientSpecification:Item Type: Laser EngraverMaximum Engraving Area: Approx. 20 x 39cm / 7.9 x 15.4inLight Wavelength: 450nmEngraving Software: For Bachin DrawPower: 5WInput Voltage: 100-240VOutput: 12V5AMaterial: Aluminum profile and thickened acrylicImage Size: 2362x4606 pixels, 0.0075mm dot pitchImage Format: PNG, JPG, BMP, SVG, DXF, G codeSupport: For XP, for win 7, for win 8, for win 10.Package List:2 x Machine Body2 x Engraving Sample Paper2 x Carved Plate4 x L Wrench1 x Wrench1 x Screwdriver1 x Safety Glasses4 x Flange Nut1 x Software U Disk1 x USB Cable2 x Cable Ties1 x Adapter1 x PlugNote:To avoid irreversible damage caused by bumps, do a good job of safety protection, please read the manual before operation, or operate under professional guidance.
