Video Review by FlixMySwitch - Episode 0001

This review is created by FlixMySwitch. The Longer Ray5 10W laser engraver was purchased independently, and this is not a sponsored review. After testing, modifying, and exploring the capabilities of the Ray5 series, the author shares personal experience, improvements, and practical tips for laser engraving beginners and enthusiasts.

At the invitation of LONGER, the review and modification experience have been organized into this article and authorized for publication as the first episode of this series.

Introduction to the Longer Ray5 10W Laser Engraver

Hello everyone, geek Andy here! Welcome to my laser diode engraver series.

After years of considering getting a laser engraver, I finally started my journey with the LONGER Ray5 10W. For technology enthusiasts who care about performance, features, and value, LONGER machines provide an impressive experience.

The Ray5 10W was my first LONGER laser engraver, and I enjoyed using it so much that I later added the Ray5 5W and 20W versions to my collection. In the future, I may also explore the Laser B1 series.

Although the Ray5 10W cannot match the power of CO₂ lasers, its diode laser technology provides excellent engraving precision with a small laser spot size. It performs well in detailed engraving projects and can also cut materials such as thin wood, MDF, and colored acrylic.

In this article, we will explore the safety requirements, technical features, suitable materials, and practical tips for getting better results with the Longer Ray5 10W.

Laser Safety Essentials

Safety is critical when using diode lasers like the Longer Ray5. Although these units are considered "low-powered" compared to industrial lasers, they are certainly not toys. Even a 0.5-watt laser diode can cause severe eye injury in an instant. Here are a few guidelines to follow:

Protective Gear: Always wear certified safety glasses when operating the laser.
Fire Risk: Keep a spray bottle and a CO2 fire extinguisher nearby, as well as a fire blanket for added safety.
Ventilation: Use effective ventilation or a smoke extractor to avoid inhaling harmful particles, especially when engraving or cutting materials that release fumes.
Toxic Fumes Warning：Laser cutting certain plastics releases extremely hazardous fumes. Materials such as ABS (found in LEGO bricks), nylon, polystyrene, and epoxy should never be used with a laser due to the risks. Even with strong ventilation, these materials release corrosive gases that can damage both your health and your machine. Always check the material's safety data sheet or conduct a burn test to ensure it is safe for laser use.

Longer Ray5 10W Laser Specifications

The Ray5 operates with a 450nm wavelength laser focused into a fine spot of 0.06 x 0.06mm, allowing for precise engraving and effective cutting on certain materials. The Ray5 excels in engraving and can cut a variety of materials including:

Wood: Plywood, MDF, and untreated wood up to 4-6mm thick
Acrylic: Best results with darker colors as diode lasers do not cut clear acrylic effectively
Leather: Natural leather engraves well; synthetic leather is not recommended as it may release toxic fumes
Other Materials: Cardboard, terracotta, slate, and even certain metals can be engraved, though not all results will be consistent.

However, avoid materials like ABS, PVC, and polycarbonate. When laser-cut, these materials release toxic gases like hydrogen chloride and cyanide, posing a severe health risk.

Ray5 Features for Enhanced Performance

Advanced Air Assist

Installing an air assist module helps clear smoke and debris from the cutting line, improving both the quality and depth of cuts. This is especially useful for tasks on wood and MDF, where precise cuts are essential.

Ventilation Requirements

Extracting smoke from the workspace is critical, particularly when cutting materials like plywood and MDF that release binding agents.

Tips for Clear Acrylic

Diode lasers like the Ray5 struggle with clear acrylic. However, you can work around this by applying coatings or using dark-colored backdrops to engrave designs. This allows you to illuminate acrylic pieces with LEDs, creating unique, glowing designs.

Upcoming Laser Engraving Topics

This series will continue exploring more laser engraving techniques, including:

Beam Focus and Focal Length: We’ll dive into the details of laser focusing to optimize engravings and cuts.
Air Assist Options: Enhancing cut quality and depth by adding airflow around the laser path.
Material Testing: From plywood and MDF to stainless steel, we’ll push the Ray5 to its limits and discover what it can achieve.

Final Thoughts

The Longer Ray5 10W laser engraver is an excellent choice for users who want to explore diode laser engraving and cutting.

Its compact laser spot, reliable performance, and wide material compatibility make it suitable for beginners, makers, and technology enthusiasts.

Through this series, we will continue testing materials, improving engraving methods, and sharing practical experience to help users achieve better engraving quality, cutting depth, and workflow efficiency.
