3.4 Software Compatibility

The laser module is compatible with most laser engraver brands and mature engraving software such as LaserGRBL and LightBurn.

Compatibility Table for Laser Tree Modules — Figure 3.3: Compatibility chart showing various laser machine models compatible with LASER TREE modules. Always verify compatibility with your specific machine.

4. Operating Instructions

The LT-80W-LE-Mini module features a 10W optical power output and double ultra-fine compressed spot technology for enhanced performance.

4.1 Focusing

This laser module has a fixed focus. For optimal cutting and engraving, use the provided focus fixing plate to set the correct distance between the laser and the material. The recommended focus length is 45mm.

Reference Settings for Laser Cutting Focus — Figure 4.1: Guide for using the focus fixing plate to achieve optimal laser focus based on material thickness.

4.2 Engraving and Cutting Capabilities

The module can directly engrave mirror stainless steel without needing to paint it black. It offers super fast engraving speeds, up to 500mm/s for 304 stainless steel. Its cutting ability is remarkable, capable of cutting through 8mm thick plywood in a single pass at a speed of 1.5mm/s.

4.3 Recommended Settings for Cutting

Refer to the table below for recommended cutting parameters for plywood:

Thickness	Passes	Speed
2mm	1	7.5mm/s
3mm	1	6mm/s
4mm	1	4.5mm/s
5mm	1	3.5mm/s
6mm	1	3mm/s
8mm	1	1.5mm/s

Note: The image in the table is a composite from the product page showing various plywood edge cuts.

4.4 Compatible Materials

The laser module can engrave materials such as MDF, rubber, wood, paper, plastic, plywood, PCB board, aluminum, stainless steel, ceramic, and stone. For cutting, it is suitable for wood, acrylic, bamboo, and MDF.

Important: The laser module is unable to engrave blue, purple, white, or transparent materials, or aluminum without an oxide layer.

Multi-Material Engraving and Cutting Examples — Figure 4.3: Showcase of various materials that can be engraved or cut with the laser module, including ceramics, bone, MDF, coated glass, black acrylic, mirror stainless steel, plywood, brushed stainless steel, leather, rubber, stone, bamboo, solid wood, alumina, pine board, and more.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your laser module.

5.1 Lens Cleaning

The laser module features a "Wind Gathering Hood" design which helps prevent smoke from damaging the focus lens, making it largely maintenance-free in this regard. However, if the lens becomes dirty or obscured, carefully clean it with a soft, lint-free cloth and a suitable optical cleaning solution. Avoid touching the lens directly with bare hands.

5.2 General Care

Keep the laser module free from dust and debris.
Ensure proper airflow around the module to facilitate heat dissipation.
Store the module in a dry, clean environment when not in use.

6. Troubleshooting

This section addresses common issues you might encounter with your laser module.

Problem	Possible Cause	Solution
Laser not firing or weak output.	Incorrect power supply; loose connections; dirty lens; software settings.	Verify 12V 3.2A-3.5A power supply. Check all cable connections. Clean the laser lens. Ensure software power settings are correct.
Laser always on at full power, no PWM control.	Incompatibility with control board; incorrect wiring of PWM signal.	Verify your machine's control board is compatible with 5V PWM modulation. Check the wiring of the PWM signal line (often the third pin on the XH2.54-3P connector). Consult your machine's manual for specific wiring diagrams.
Poor engraving/cutting quality.	Incorrect focus; incorrect speed/power settings; material not suitable.	Ensure the laser is properly focused using the focus fixing plate. Adjust speed and power settings according to the material (refer to Section 4.3). Confirm the material is compatible (refer to Section 4.4).
Module overheating.	Insufficient airflow; prolonged high-power operation.	Ensure the cooling fan is unobstructed and functioning. Allow the module to cool down between long operations.
