1. Preparation

① Equipment and Materials

Device: Nano Pro Laser Engraver
Software: LightBurn
Material: Synthetic leather (Note: May emit hazardous gases during engraving; wear a mask)
Additional Tools:
Tape: To secure the leather and prevent shifting
Air Purifier: To reduce harmful fumes and maintain air quality

② Device Setup

Place the Nano Pro on a stable work surface.
Power on the device and ensure the laser head is functioning properly.
Connect the Nano Pro to a computer via USB cable.

2. Design Configuration

① Create or Import Your Design

Use design software to either create a new design or import an existing one.

② Optimize the Design

Adjust the size and position of the graphic to fit your leather piece appropriately.

3. Engraving Parameter Settings

The quality of leather engraving is influenced by laser power and speed settings. In LightBurn:
Select your design and open the Cut/Layer settings.
Double-click the layer assigned to the artwork.
Set the mode to Fill, and enable Constant Power Mode.
Adjust the settings as follows:
Line Interval: 0.06 mm
Speed: 10000 mm/min
Max Power: 50%
(Note: Excessive power can cause burning or melting of the leather.)

⚠️ Tip: Test settings on a small leather scrap before full-scale engraving to account for variations in leather type and thickness.

4. Engraving Process

① Secure the Leather

Lay the leather flat in the Nano Pro's working area. Use tape to fix all four corners to prevent movement or curling during engraving.

② Adjust Focus

Adjust the laser head’s focus so that it is correctly distanced from the leather surface. The Nano Pro is equipped with an adjustable Z-axis; use the lift switch to achieve focus.

③ Turn on the Air Purifier

Aim the purifier hose toward the leather (outside of the engraving area).
Connect power and turn on the side switch.
Rotate the knob on the front lower-right corner clockwise to the On position.
The green indicator light will illuminate.
Continue turning the knob to increase airflow as needed.

④ Positioning

Use the "Frame" function in LightBurn to preview the engraving area. Adjust the design size and position to ensure it fits within the engravable region of the leather.

⑤ Start Engraving

Click the "Start" button in LightBurn. The laser will begin engraving according to the configured parameters.
Monitor the engraving process to ensure even operation and avoid overheating.

⑥ Post-Engraving

After the engraving is complete, inspect the result. Gently clean the surface if necessary.

Conclusion

Engraving leather with the Nano Pro laser engraver is a precise and rewarding process. By properly preparing your materials, configuring your design in LightBurn, and fine-tuning engraving parameters, you can achieve clean, professional results. Always test on scrap leather before full production, and ensure good ventilation during operation. With the right setup and care, the Nano Pro makes it easy to add custom, high-quality details to any leather project.
