2. Safety Information
WARNING: This is a Class 4 laser product. Direct exposure to the laser beam can cause severe eye and skin damage. Always wear appropriate laser safety goggles (OD4+ or higher) when operating this device. Never look directly into the laser beam or its reflection. Ensure the work area is properly ventilated and free of flammable materials.
- Always wear certified laser safety goggles during operation.
- Do not operate the laser module without the protective cover.
- Keep children and pets away from the operating area.
- Ensure proper ventilation to remove fumes generated during engraving/cutting.
- Never leave the laser module unattended while in operation.
- Be aware of reflective surfaces that could cause unintended laser exposure.

4. Setup and Installation
4.1 Compatibility
This laser module is specifically designed for upgrading 3018 and 3018 Pro CNC machines. It is also compatible with other CNC machines that have mounting brackets similar in size to the CNC 3018 series.

4.2 Mounting the Laser Module
- Ensure your CNC machine is powered off and disconnected from the power source.
- Carefully remove any existing spindle or laser module from your CNC machine.
- Align the cylindrical body of the LASER TREE module with the mounting brackets of your 3018/3018 Pro CNC machine.
- Secure the module firmly in place using the appropriate fasteners provided with your CNC machine or the laser module.
4.3 Electrical Connection
The module uses a 3-pin connector (XH2.54-3P) for power and PWM control. Connect the cable to the corresponding port on your CNC control board. The pins are typically labeled VCC (Power), GND (Ground), and PWM (Pulse Width Modulation).
- VCC: DC 12V 2A input
- GND: Ground
- PWM: 5V PWM modulation support
4.4 Air Assist Connection
For optimal cutting and engraving results, connect the air pipe to the air assist nozzle on the laser module. If using an external air pump (not included), connect the air pipe from the module to your air pump. The air tube suggestion is an outer diameter of 6mm and an inner diameter of ≥4mm.

4.5 Focusing the Laser
The module features a fixed-focus design with a built-in FAC lens for a small spot size (0.08*0.08mm). Use the provided focus fixing plates (3mm, 4mm, 5mm) to set the optimal working distance for different materials. Place the appropriate plate on the material surface, lower the laser module until it touches the plate, then remove the plate. This sets the correct focal length.
5. Operating Instructions
5.1 General Operation
- Ensure all connections are secure and safety goggles are worn.
- Place the material to be processed on the CNC machine's workbed.
- Set the laser focus as described in Section 4.5.
- Load your design file into your CNC control software (e.g., GRBL, LightBurn).
- Adjust laser power and speed settings according to the material and desired effect. Start with lower power and higher speed for testing.
- Initiate the engraving or cutting process. Monitor the operation closely.
5.2 Material Compatibility and Performance
This 5W laser module can be used on a variety of materials, including:
- Wood
- MDF board
- Leather
- Bamboo
- Black Acrylic
- Stainless Steel (direct engraving without black paint)
Cutting Capabilities:
- 3mm plywood: Cut in one pass at approximately 1.5mm/s (90mm/min) with 45mm focus length. (Note: Image shows 200mm/min for 3mm plywood, use as a guideline).
- 5mm pinewood: Cut in one pass at approximately 80mm/min.
- 5mm acrylic: Cut in one pass at approximately 25mm/min.

6. Air Assist Function
The integrated air assist system significantly improves cutting and engraving quality. It directs a stream of air onto the focal point, which helps to:
- Remove smoke and debris from the cutting path, resulting in cleaner edges.
- Prevent charring and discoloration of materials.
- Increase cutting efficiency and speed.
- Extend the lifespan of the laser lens by keeping it clear of residue.

7. Maintenance
7.1 Cleaning the Protective Window Glass
The laser module's protective window glass must be kept clean. Fingerprints, dust, or debris on the window can significantly affect the laser's cutting ability and cause power decrease. Regularly inspect and gently clean the window with a soft, lint-free cloth and a suitable lens cleaning solution (e.g., isopropyl alcohol) if necessary. Avoid abrasive materials.
7.2 Cooling System
The module features a built-in fan cooling system (Fan Speed 10000 rpm). Ensure the fan vents are not obstructed to maintain optimal heat dissipation. A well-maintained cooling system contributes to the module's long lifespan (up to 20,000 hours).
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser power is weak or inconsistent. |
|
|
| Laser does not turn on. |
|
|
| Poor cutting/engraving quality (e.g., charring, incomplete cuts). |
