1. What materials can the Diode Laser Engraver work on?

The engraver works on a wide range of materials including wood, acrylic, glass, leather and certain metals (e.g., anodized, painted or coated metals). Results on bare metals may require marking paste, pre-treatment or higher-power modules.

2. What is the maximum engraving area and why does it matter?

The machine offers a 400 x 410 mm engraving area, allowing you to engrave larger single pieces or multiple smaller items at once, improving throughput and enabling larger designs.

3. What engraving speed can I expect?

Maximum engraving speed is 20,000 mm/min. Actual usable speed depends on material, laser power, focal lens and the level of detail — faster for light marking, slower for deep engraving or cutting.

4. Which file formats are supported?

The engraver supports common formats including JPG, SVG, PNG, BMP, G-code and DWG, so it is compatible with most design programs and vector/canvas workflows.

5. What are the differences between the available laser modules?

Three modules are available: LU2-4-SF and LU2-4-LF (optical power 4500–5500 mW) and LU2-2 (1000–1600 mW). They differ in focal spot size, focal length and electrical specs — LU2-4 variants offer higher power for deeper marking/cutting; LU2-2 is lower power with a smaller focal spot for finer detail.

6. What are the laser wavelengths, focal lengths and focal spot sizes?

All modules operate around 445 nm (±10 nm). Focal lengths: LU2-4-SF = 30 mm, LU2-4-LF = 50 mm, LU2-2 = 50 mm. Approximate focal spot sizes: LU2-4-SF ~0.12 × 0.15 mm, LU2-4-LF ~0.17 × 0.25 mm, LU2-2 ~0.07 × 0.06 mm.

7. How long does the laser head last?

The laser head is rated for over 10,000 hours of operation under normal use and with proper cooling and maintenance.

8. What cooling system does the machine use?

The unit uses an air-cooled laser head system to maintain optimal operating temperature and prolong component life. Ensure adequate ventilation and keep intake/exhausts clear.

9. How do I connect and send files to the engraver?

You can transfer designs via USB, Wi‑Fi or TF card (microSD). Supported file types include raster and vector formats; some users also send G-code produced by design software like LightBurn, LaserGRBL or other CAM programs.

10. Is the Diode Laser Engraver suitable for cutting as well as engraving?

Yes — in pulsed laser mode the machine can both engrave and cut thinner materials. Cutting performance depends on laser power, focal length, material type and thickness; multiple passes or higher-power modules may be required for thicker materials.

11. What safety precautions should I follow?

Always wear appropriate laser safety eyewear rated for 445 nm, avoid exposure to the beam, work in a well-ventilated area (some materials emit fumes), never leave the machine unattended while running, and avoid engraving hazardous or highly flammable coatings.

12. What routine maintenance is required?

Regularly clean the lens and optics, keep the air-cooling vents and fans free of dust, check electrical connections, and inspect mounts for looseness. Replace consumable parts (e.g., lenses or fans) as needed to maintain performance.

13. What if my engraver is not firing or output is weak?

Check power and data connections, confirm correct firmware and settings, verify the selected laser module and current/power limits, ensure the laser is focused at the proper focal length, and confirm safety interlocks (if present). If issues persist, contact support.

14. What are recommended settings to start with?

Start with lower power and faster speed for test marks on scrap material, then adjust: increase power or reduce speed for deeper marks/cuts, decrease power or increase speed for lighter engraving. Always run a test cut/engrave on a scrap piece before final work.

15. Is the machine suitable for beginners?

Yes. The engraver is designed for both hobbyists and professionals, with broad format support and an easy connectivity workflow. Beginners should follow safety guidelines, perform test runs, and learn basic focus and material settings before tackling large projects.
