Its lighter weight makes it ideal for on-the-go tasks in small studios or classrooms.
LONGER Ray5 2500mW Engraver
This model provides a lower-power, beginner-friendly option suitable for light engraving and precious-metal tagging. It offers a 5.1″ × 5.5″ working area, Wi-Fi connectivity, and compatibility with LightBurn and LaserGRBL. Its space-saving design and protective features make it a practical entry point for hobbyists who want to explore engraving on wood, leather, acrylic, and light metals without a large upfront investment.
LONGER Ray5 20000mW with 3.5″ Touch Screen
This high-end Ray5 variant combines 20W-class power with a 3.5-inch touchscreen for intuitive control. It supports 0.05 mm stainless steel, 15 mm pine wood, and 8 mm acrylic in a single pass, with potential for deeper material processing through multiple passes. The combination of power, precision, and a refined user interface makes it a popular choice for serious makers and design studios working on metal and mixed-material projects.
Buying Guide
- Power and material compatibility: For engraving metal, look for at least 10000–20000 mW with a suitable laser wavelength and cooling to avoid overheating during runs. Consider whether multi-pass cutting is necessary for thicker metals.
- Precision and spot size: Smaller laser spot sizes (0.04–0.08 mm) enable finer detail. Ensure engraving accuracy around 0.01 mm if your designs require high fidelity.
- Working area and enclosure: A larger workspace supports bigger designs; an enclosed or well-ventilated system helps with safety and material accommodation.
- Cooling, safety, and controls: Air assist improves cutting quality, while emergency stop and protective eyewear are essential. Check for a touchscreen or reliable software like LaserGRBL/LightBurn compatibility.
- Connectivity and workflow: USB, Wi-Fi, TF card, and app integrations offer flexibility. Multi-device control can boost productivity in shared studios.
- Rotary attachments: If you plan cylindrical engravings (tumbler or bottle designs), ensure the machine supports a rotary roller kit with adjustable jaws and clamping options.
- Ease of use and setup: Beginner-friendly models with pre-assembly and included safety gear reduce setup time. Look for documented manuals and active customer support.
- Software compatibility: Verify compatibility with common engraving software like LightBurn and LaserGRBL, as well as native interfaces on the device.
- Safety and certification: For metal engraving, confirm the laser class and safety features to minimize risk during operation and storage.
