Installation 3.1 Installation Overview A complete working system consists of the laser engraving cabinet, its vent, a water tank (not included) with a pump (included), all applicable connection cables, and the laser and access keys. The cabinet can use designs provided by the enclosed engraving software by direct or internet connection with your computer;...
  • Page 19 Step 3. Open the engraver’s cover and take out the accessories pack from the main bay in the front of the machine. Check that you have received all of the following: a power cord, 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 set of hex wrenches, a tube of silicone sealant, an acrylic focusing tool, keys, and this manual.
  • Page 20 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 supply. To install your pump, fill a dedicated tank with at least 7.5 litres (1.6 gal.) of distilled water.
  • Page 21 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 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 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.
  • Page 24 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 The threshold for the lowest setting is 10%. The laser will not fire at any setting lower than this. It is NOT recommended to use the laser tube at full capacity, especially for extended periods. The recommended maximum power setting is 70%, as prolonged use above that amount will shorten your laser's service life. To increase engraving depth, increase the amount of energy per unit area by increasing the laser's power or the number of loops or by slowing down the speed parameter.
  • 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 39 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 40 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. 5.3.2 Cleaning the Main Bay and Engraver Check at least once a day whether dust has accumulated in the main engraving bay. If so, it must be removed. The exact cleaning interval and requirements strongly depend on the material being processed and the operating time of the device.
  • Page 41 4. Remove the pressurised air hose and laser guide connections. 5. 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. 6.
  • Page 42 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 semi-transparent mirror that should be checked at the same time.
  • Page 43 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 44 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 45 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.
