Precision and Power. The PLH3D-XT8 stands out with its 45W of maximum optical power, enabling it to cut through materials like 15mm wood with exceptional speed and precision, and even thicker materials with multiple passes. Its advanced features, such as the superior focus depth, integrated air-assist nozzle, and two operating modes for grayscale and full-power cutting, make it versatile for a wide range of applications

Integration Ease. Ease of installation is a key feature of the PLH3D-XT8, making it an accessible upgrade for LongMill CNC users. The laser head comes with a comprehensive kit, including a mount, height reference tool, and all necessary wiring, ensuring a straightforward setup process. This user-friendly approach allows CNC enthusiasts to quickly add laser capabilities to their existing setup, expanding their creative and production possibilities without extensive modifications.

Enhanced Safety Features. Safety is paramount when operating high-power laser equipment. Sienci Labs emphasizes the importance of safety precautions when using lasers, and the PLH3D-XT8 addresses this with an integrated signaling LED that indicates when the laser is armed and ready to fire. This feature is essential for preventing accidental activation and ensuring operator safety. Additionally, the LED serves as an overheating warning, automatically shutting down the laser if temperatures exceed safe limits, thereby protecting both the user and the equipment.

For those looking to enhance their LongMill CNC machine with advanced laser capabilities, the PLH3D-XT8 offers a compelling mix of power, precision, and safety, provided the necessary precautions and settings adjustments are made to ensure a safe and efficient operation.

Best Laser Engraver for Woodworking

Mounting the PLH3D-XT8 laser head onto the LongMill CNC machine transforms it into a versatile tool for woodworking, offering the ability to execute intricate designs and smooth cuts on a variety of woods including oak, pine, and other hardwoods, as well as effortlessly slicing through softer materials like balsa and MDF. This enhancement not only broadens the creative scope for producing ornate artworks but also functional items, with the ability to tweak the depth, shade, and clarity of engravings by adjusting the laser's power, focal length, speed, and number of passes. Its user-friendly design is particularly appealing to hobbyists, bringing high-level woodworking projects within reach.

Cutting & Engraving Wood with LongMill CNC Laser 


The effectiveness of the LongMill Laser Upgrade Kits in wood cutting and engraving is significantly affected by the wood's characteristics, including its type, hardness, moisture content, and texture. Woods like balsa and high-grade plywood, known for their uniformity, are particularly compatible with laser processes. High-grade plywood, which typically features a lightweight balsa core encased by harder wood layers, offers a consistent surface ideal for laser applications. The efficiency and uniformity in laser cutting these types of wood are due to their smooth and defect-free composition. When choosing wood for laser-based projects, it's important to assess the material's uniformity. Although some balsa variants are economical, they may contain sections of denser wood, potentially hindering the laser cutting efficiency. Similarly, for high-grade plywood, the consistency of the material is paramount to achieve the best laser cutting or engraving outcomes.
