3.2 Mounting the Laser Module

1. Attach the provided mounting board to your CNC machine or laser engraver's gantry according to your machine's specifications.
2. Secure the AENBUSLM 40W Laser Module to the mounting board using the appropriate screws. Ensure it is firmly attached and stable.

3.3 Connexions elèctriques

1. Connect the 3P control line to the XH2.54-3P socket on the laser module. This line typically carries PWM signals for laser power control and ground.
2. Connect the other end of the 3P control line to the corresponding laser control port on your CNC controller board. Refer to your CNC machine's manual for specific pin assignments.
3. Connect the external power cord to the laser module's power input and then to a compatible 12V DC power supply (minimum 3.2A recommended).

3.4 Enfocament

The AENBUSLM 40W Laser Module features a fixed-focus design, meaning the optimal focal length is pre-set. However, some CNC setups may require minor height adjustments for optimal performance. A review mentions an adjustable focal length via a set screw on the mount, which might be an additional feature depending on the specific batch or mounting solution.

1. Place the focus fixing plate on the material surface.
2. Adjust the height of the laser module until the bottom of the module (or the laser nozzle) touches the focus fixing plate.
3. Remove the focus fixing plate. The laser is now set to the optimal focal distance for most materials.

3.5 Air Assist

The module has a built-in air assist system. This system automatically provides a stream of air to the laser's focal point during operation, which helps to:

• Blow away smoke and debris, resulting in cleaner cuts and engravings.
• Reduce charring and discoloration on the material.
• Improve cutting efficiency and depth.

4. Instruccions de funcionament

This section provides general guidelines for operating the AENBUSLM 40W Laser Module for various applications.

4.1 Materials compatibles

The laser module is suitable for engraving and cutting a wide range of materials, including:

• Wood (Pine board, bamboo, basswood, plywood)
• Metal (Mirror stainless steel, lacquered metal, aluminum oxide)
• Acrylic (Black acrylic)
• Paper i cartró
• Cuir
• Pedra
• Ceràmica

• Check Control Line: Verify the 3P control line is securely connected to both the laser module and the CNC controller.
• Configuració del programari: Confirm that the laser power (PWM) is set correctly in your engraving software and that the laser is enabled.
• Focus: Re-check the focus distance. An out-of-focus laser will have a weaker or diffused beam.
• Lens Condition: Inspect the protective lens for dirt, scratches, or damage. Clean or replace if necessary.

6.2 Poor Engraving/Cutting Quality

• Focus: Ensure the laser is precisely focused on the material surface.
• Speed and Power: Adjust engraving/cutting speed and laser power settings. Different materials require different parameters.
• Air Assist: Verify the built-in air assist is functioning. Lack of air assist can lead to charring and poor edge quality.
• Qualitat del material: Ensure the material itself is suitable for laser processing and free from defects.

6.3 Sobreescalfament

• Fan Obstruction: Check if the cooling fan vents are blocked. Clear any debris.
• Temperatura ambient: Operate the laser in a reasonably cool environment.
• Funcionament continu: While designed for extended use, prolonged operation at 100% power in high ambient temperatures may lead to minor power decrease. Allow for cool-down periods if necessary.
