Laser engraver Longer RAY5 mini 2.5W — compact desktop diode engraver 2.5W

Longer RAY5 mini 2.5W is a compact desktop diode laser engraver with a 2.5W rated laser module designed for precise engraving and light cutting tasks. The unit offers a 130 × 140 mm working area, a focused 0.04 × 0.04 mm laser spot and a 450 nm wavelength, enabling detailed etching on wood, leather, cardboard and coated metals. The pre-assembled frame, small footprint and USB/Wi‑Fi connectivity make the device suitable for hobbyists, small workshops and rapid prototyping in limited workspaces.

Advantages

The device combines a compact aluminum-alloy body with a high-resolution laser spot and a maximum head speed of 12,000 mm/min, which together enable accurate, repeatable results while taking up minimal space. Factory assembly and a 2 mm focusing block reduce setup time and simplify first-use calibration. Support for common file formats and cross-platform software compatibility allows easy transfer of designs from graphics and CAD programs. Built-in safety features such as X/Y limit switches, an emergency stop button, an acrylic protective screen and provided safety glasses help reduce operational risks.

Suitable for

• Personalization of small items and gifts (keychains, nameplates, jewelry)
• Prototype marking and small-batch production for workshops and makerspaces
• Hobby engraving on wood, leather, acrylic, and coated metals
• Cutting thin materials and preparing model parts (thin plastics, paper, balsa)

How to use

Place the Longer RAY5 mini on a stable, level surface and connect the supplied power adapter. Install the focusing block to set the laser-to-material distance, then secure the workpiece within the 130 × 140 mm working area. Load your design in compatible software (for example LaserGRBL or LightBurn), select the appropriate material profile and adjust power and speed settings. Transfer the job via USB or Wi‑Fi, preview the job if the software supports it, put on the supplied safety glasses and start the engraving. Use the Emergency Stop button or software pause to stop the job immediately if needed.

Usage recommendations

Test settings on a scrap piece of the same material before running a final job, beginning with lower power and slower speed and gradually increasing until the desired result is achieved. Keep ventilation in the workspace and avoid inhaling fumes when processing materials such as PVC or coated metals; use recommended materials and avoid those that release hazardous gases when lasered. Regularly clean the lens and work area and check limit switches to maintain stable performance and long module life.
