It ships with safety glasses and test materials, aiming to deliver a straightforward, beginner-friendly workflow for stone applications as well as other media.
Longer Ray5 20,000mW Laser Engraver
The Longer Ray5 stands out for very high output power and a large working area of 400 x 400 mm. Powered by a 20,000 mW laser, it can perform single-pass cuts through pine and thicker materials and handle multiple passes for deeper engraving or cutting tasks. It features a 256-color palette for in-house color engraving and a high-precision dot size of 0.08 x 0.1 mm with 0.01 mm engraving accuracy. A 240 MHz ESP32 chipset enables multi-machine coordination from a single computer and supports continuous operation, which can be advantageous for stone projects requiring consistent, repeatable results across batches.
Buying Guide: Key Purchase Considerations
- Project scope and material compatibility: For stone, assess power, focusing ability, and heat management. Higher wattage models typically perform better on dense materials, but require ventilation and safety considerations.
- Engraving vs. cutting capability: If you need etched text or patterns on stone, prioritize precision (0.01 mm positioning accuracy) and stable speed. For cutting stone or cutting through coated surfaces, ensure the machine can manage the required depth and material strength.
- Working area and footprint: Stone projects often benefit from larger beds to accommodate plaques or tiles. Balance the working area with your available workspace to avoid bottlenecks.
- Power supply and safety: Higher-power machines may require enhanced electrical and ventilation setups. Check compliance certificates, protective gear, and user safety features to reduce risk when operating near stone dust and fumes.
- Software compatibility and learning curve: Look for compatibility with common software such as LightBurn or LaserGRBL, and consider whether preassembled units or quick-start setups save time for beginners.
- Maintenance and consumables: Consider fan and lens life, ease of lens replacement, and availability of replacement parts. Stone engraving can generate heat and dust; ensure you have suitable cleaning and maintenance routines.
- Cost vs. value: Higher power often brings better performance on stone but at a higher upfront cost. Evaluate total cost of ownership, including safety gear and any required upgrades.
- Community and support: A strong user community and responsive vendor support can help with troubleshooting, material-specific settings, and project optimization for stone engraving.
