4.1 Compatibility and Power Requirements

The NEJE E40 module is compatible with DC3.3V-12V PWM/TTL input signals. It is designed for easy integration with NEJE Master 2S/Plus/Max machines and can also be adapted for use with other CNC routers, Arduino, and 3D printer systems. A stable 12V 3A-4A power supply is required for optimal performance.

4.2 מאָדולע ינסטאַלירונג

1. מאָונטינג: Securely attach the NEJE E40 laser module to your engraving machine's mounting bracket. Ensure it is firmly in place to prevent movement during operation.
2. Z-Axis Adjustment: Use the provided Z axis adjuster to set the initial height of the laser module above your working surface.
3. קאַבלע קשר: Connect the 4-pin cable to the laser module and your machine's control board. Ensure the PWM/TTL signal line (yellow and black 2-pin) and the 3-pin input line are correctly connected according to your machine's wiring diagram.
4. מאַכט צושטעלן: Connect the recommended 12V 3A-4A power supply to your machine.

4.3 Air Assist Setup

For cleaner cuts and reduced charring, an air assist system is recommended. The NEJE E40 module includes a built-in high-pressure air nozzle.

1. Connect Air Nozzle: Attach the CNC metal air nozzle to the module if not already pre-installed.
2. Connect Trachea: Connect the 4mm PVC trachea to the air nozzle.
3. לופט פּאַמפּס: Connect the other end of the trachea to an external air pump (not included) capable of providing 0.6-1.5 Mpa pressure.

This diagram illustrates the NEJE A40640 engraving module, showing its internal components, eye protection feature, and the recommended setup for air assist (0.6-1.5 Mpa) with a focus point of 22mm for cutting plywood up to 18mm thick.

5.1 Software and Control

The NEJE E40 module is compatible with various control software, including LightBurn, LaserGRBL, NEJE Controller (PC), and NEJE Android/iOS Apps. Ensure your chosen software is correctly configured for your machine and the E40 module.

5.2 פאָקוס אַדזשאַסטמאַנט

Achieving the correct focus is critical for optimal engraving and cutting results. The NEJE lens provides a clear focus without scattered light, and the focal distance is adjustable.

1. ערשטע פאָקוס: Place a test material under the laser.
2. סטרויערן די הייך: Slowly adjust the Z-axis (module height) until the laser spot on the material is at its smallest and most intense point. This is your focal point.
3. פיין טונינג: Perform small test engravings or cuts and fine-tune the focus for the best results on your specific material.

This image demonstrates the precision of the NEJE module, showing a significantly smaller laser focus spot (0.04mm*0.06mm) compared to other modules (0.08mm*0.1mm), resulting in clearer and more detailed engravings.

This image illustrates the NEJE module's ability to achieve a longer depth of field and cleaner, thicker cuts. It shows a vertical cut through material, indicating high verticality and clean edges, unlike other modules that may produce carbonized substances and edge errors.

5.3 Material Compatibility and Performance

The NEJE E40 module is capable of engraving and cutting a wide range of materials:

• ינגרייווינג: MDF, balsa, paper, wood, fabric, plastic, leather, plywood, foam paper, anodized aluminum, stainless steel (requires good focus), painted metal, painted tile, bone, film-coated transparent acrylic, film-coated stainless steel, film-coated glass, felt.
• קאַטינג: 4mm plywood (1 pass at speed 200), 3mm black acrylic (1 pass).

This image displays a variety of materials suitable for processing with the NEJE laser module, including plywood, kraft paper, leather, plastic, black anodized aluminum, corrugated board, solid wood, veneer, bamboo, MDF board, black acrylic, stamp rubber, canvas art, non-woven fabric, painted metal, painted tile, bone, film-coated transparent acrylic, film-coated stainless steel, film-coated glass, and felt.

6. וישאַלט

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

• לענס רייניקונג: Periodically inspect the laser lens for dust, debris, or residue. Clean gently with a specialized lens cleaning solution and a lint-free cloth to maintain laser beam quality.
• פאָכער וישאַלט: The module features an intelligent temperature sensor control and a 10000 rpm 40mm fan. Ensure the fan intake and exhaust vents are clear of obstructions to allow for proper cooling. Clean any accumulated dust from the fan blades.
• אַלגעמיינע רייניקונג: Keep the exterior of the module clean and free from material dust or debris.
