    Step 3. Check that you have received all of the following: two power cords, a ground wire, USB and Ethernet cables, a USB flash drive with engraving software included, a water pump and water piping, an exhaust pipe with a hose clamp, a ceramic resistor and its manual, a set of Allen keys, a tube of silicone sealant, an acrylic focusing tool, access keys, laser keys, repair wrenches, and this manual.
  • Page 20: Water Cooling Installation

    3.5 Water Cooling Installation The provided water pump is essential to your engraver's performance and longevity. When this laser works without a properly maintained cooling system, its glass tube WILL explode from excess heat. NEVER touch or adjust your engraver's water supply while the pump is connected to power. To install your pump, fill a dedicated tank with at least 7.5 litres (1.6 gal.) of distilled water.
  • Page 21: Exhaust System

    3.6 Exhaust System This engraver doesn’t come with an inbuilt exhaust fan. Follow the steps to set an exhaust system before use. 1. Connect the provided exhaust pipe to the port of the laser engraver, and the other end to your exhaust fan. Expand the pipe if longer is needed.
  • Page 22: Initial Testing

    3.9 Initial Testing Emergency Shutoff Because of the risk of fire and other hazards during engraving, this engraver includes a large and easy-to-reach emergency stop button near the control panel. Press it down to stop the laser tube instantly. When your engraver arrives, its e-stop is already pressed. Release the e-stop and press the reset button to allow the laser to function.
  • Page 23: Air Assist

    Water Shutoff Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser automatically when the water cooling system malfunctions. After ensuring that the emergency stop button and cover protection both work, you should also test that the water shutoff works properly before conducting any other work on your machine.

    4. Operation 4.1 Operation Overview Operate this laser marking machine only in accordance with all the instructions provided in this manual. Failure to follow the proper guidelines detailed here can result in property damage and personal injury. This section will address only some of the options and features provided by the operation software. Before beginning to use the machine, make sure that you have read this entire manual (particularly the Safety Information above), the separate software manual, and any and all warnings provided on the machine itself.
  • Page 25: Instructions For Specific Materials

    Step 8. Customise your design's contrast and engraving depth by adjusting the parameters in your engraving software or directly through the control panel. If your engraving instructions detail the power setting in milliamperes, use the following conversion chart to find the appropriate power setting: Power 100% Current (mA)
  • Page 26 Ceramics When engraving on ceramics, generally use moderate to high power. Using more loops rather than higher power and lower speed can help avoid cracking the material during work. Be mindful of the health risk posed by dust generated from ceramic engraving, especially for repetitive industrial applications. Depending on the material and the amount of work, a fan or even full ventilation system may be required to address the problem.

  • Page 38: Maintenance

    5. Maintenance 5.1 Maintenance Overview The use of procedures other than those specified herein may result in hazardous laser radiation exposure. Before any cleaning or maintenance work, always switch off the device and disconnect it from its power supply. Always keep the system clean, as flammable debris in the working and exhaust areas constitutes a fire hazard. ONLY allow trained and skilled professionals to modify or disassemble this device.
  • Page 39: Main Bay & Engraver

    If the water remains visibly clean at all times, it is still recommended that you clean the water tank about once a month as a precaution, changing the water as you do so. If you use an industrial water chiller instead of the provided pump, follow its separate instructions for maintenance but similarly ensure that the water used remains cool, clean, and pure.
  • Page 40 Remove the pressurised air hose and laser guide connections. Once positioned over your clean lens-cleaning tissue, remove the lens from the lens holder by carefully turning the lens holder and letting the lens and its O-ring drop onto the cleaning cloth. Examine the O-ring and, if necessary, clean it with a cotton bud and a lens-cleaning tissue or cloth.
  • Page 41: Mirrors

    5.3.4 Cleaning the Mirrors The mirrors should be similarly cleaned if there is any debris or haze on their surface to improve performance and avoid permanent damage. The 1st mirror is located in the back left of the machine beyond the far end of the Y axis. The end of the laser tube closest to this mirror is itself a semitransparent mirror that should be checked at the same time.
  • Page 42: Laser Tube

    5.4.1 Laser Tube Alignment To test the alignment of the laser tube with the 1st mirror, cut out a piece of tape and place it on the mirror's frame. DO NOT place the tape directly onto the mirror. Turn on the machine and set the power level to 15% or lower. Press Pulse to manually fire the laser.
  • Page 43: First Mirror

    5.4.2 1st Mirror Alignment After ensuring the laser is well aligned between the laser tube and 1st mirror, check the alignment between the 1st and 2nd mirrors. First, use the direction arrows on the control panel to send the 2nd mirror to the back of the bed along the Y axis.
  • Page 44: Second Mirror

    5.4.3 2nd Mirror Alignment After ensuring the laser is well aligned between the 1st and 2nd mirrors, check the alignment between the 2nd and 3rd mirrors. Repeat the steps and adjustments above, taking care to use the tape on the mirror's frame and not its surface. 5.4.4 3rd Mirror Alignment After ensuring the laser is well aligned between the 2nd and 3rd mirrors, check the alignment between the 3rd mirror and the workbed.
