Longer RAY5 Mini S Laser Engraver – Compact 2.5W / 3.5W / 5.5W Diode Laser Engraving & Cutting Machine with Class I Safety, 0.04mm Precision

The pendant is 25mm across and the text needs to be legible. The leather patch is going on a jacket and the detail has to hold at close range. The keychain says "class of 2025" in a font size most machines smear. The Longer RAY5 Mini S was built for exactly this kind of work — and for the person doing it on a bedroom desk, a kitchen table, or a dorm shelf where a full-size engraver simply doesn't fit. Available in 2.5W, 3.5W, and 5.5W, the Mini S delivers a 0.04mm compressed laser spot, 12,000 mm/min engraving speed, and full Wi-Fi + App control in a 1.47kg pre-assembled machine ready to run in under a minute. For beginners, students, gift makers, jewelry designers, and anyone who needs professional engraving precision without professional machine bulk, the RAY5 Mini S is the first laser that actually fits your life.

Pre-Assembled & Ready in 1 Minute – No Setup, No Learning Curve

The RAY5 Mini S ships fully assembled. No frame to build, no belt to tension, no firmware to flash. Unbox, connect, load a file, and engrave — under one minute from box to first mark.

The dovetail fixed-focus laser head adjusts to different material thicknesses in seconds — no calipers, no shims, no recalibration. Switching from 3mm plywood to 5mm leather is a five-second height change. Step-by-step manuals and video tutorials are included for users who want guided instruction from the very first use.

0.04mm Compressed Laser Spot – Fine Text, Sharp Lines, Clean Detail

The 2.5W and 3.5W variants use a 0.04×0.04mm compressed laser spot — one of the finest at this price point. At this spot size, 4pt fonts engrave legibly on leather, fine vector lines stay crisp, and dithered grayscale photos show true tonal range on wood.

The 5.5W tier uses FAC compression at 0.08×0.08mm with higher power density — optimized for cutting while maintaining sharp engraving results. All variants deliver 0.01mm engraving accuracy and 12,000 mm/min speed, up to 20% faster than comparable models.

Class I Safety – Fully Certified, Safe for Home, School & Shared Spaces

The Mini S is certified to Class I laser safety standards — the same classification as a CD player or barcode scanner. Under normal operating conditions, no protective eyewear is required.

For households with children, shared office spaces, and educational environments where open-frame Class 4 lasers create concerns, Class I certification is the deciding factor. Also included on the 5.5W version: built-in X/Y limit switches, emergency stop button, and 3.5-inch touchscreen — the complete safety and control package.

130×140mm Work Area – Full-Size Performance in a Mini Frame

For the 2.5W and 3.5W, 5.5W variants, the 130×140mm work area is purpose-matched: keychains, pendants, dog tags, leather patches, small wooden signs, coasters, custom labels — the most popular first-laser applications, covered completely within that compact footprint.While retaining the compact 1.47kg Mini S body and using the same FAC compressed 0.04×0.04mm diode module.

FAQs

1. What is the difference between the LONGER RAY5 Mini and the RAY5 Mini S?
The RAY5 Mini S is an upgraded version of the RAY5 Mini with several improvements.

It includes a protective enclosure that helps contain laser light and smoke during operation, making it safer for use at home, in schools, or shared workspaces.

All versions (2.5W, 3.5W, and 5.5W) have the same 130 × 140 mm working area.

2.5W and 3.5W models are ideal for detailed engraving on keychains, jewelry, and small crafts.
The 5.5W version is better suited for cutting thicker materials and also features Class I certified safety.
2. Is the LONGER RAY5 Mini S suitable for beginners with no laser experience?
Yes. The RAY5 Mini S is designed specifically for beginners.

The machine arrives fully assembled and can be set up in less than one minute. The dovetail fixed-focus laser head eliminates the need to adjust focus when switching between materials.

Users can operate it through the MKSLaser mobile app (Android and iOS) to import photos, adjust settings, and start engraving directly from a smartphone.

For advanced users, the machine also supports LaserGRBL (free, Windows) and LightBurn (paid with a 30-day trial). Step-by-step manuals and video tutorials are included to help beginners get started quickly.
3. What materials can the LONGER RAY5 Mini S engrave and cut?
The RAY5 Mini S supports engraving on more than 300 materials, including wood (plywood, basswood, MDF, balsa), leather, fabric, paper, cardboard, coated or anodized metals, opaque or coated acrylic, cork, coated ceramics, and most plastics (except PVC).

Cutting capability depends on the laser power.

2.5W can cut paper, thin cardboard, balsa (≤3 mm), and thin fabric.
3.5W can cut light wood (≤5 mm) and thin acrylic.
5.5W can cut basswood up to 8 mm and acrylic similar to other 5W-class lasers.

Lower power versions are best for precision engraving, while the 5.5W model is recommended for users who need stronger cutting performance.
4. Can the LONGER RAY5 Mini S work without a computer?
Yes. The RAY5 Mini S supports offline operation.

You can load files onto a TF card and run the engraving job directly on the machine without connecting a computer.

The machine also supports Wi-Fi control through the MKSLaser mobile app, allowing jobs to be sent and monitored from a smartphone.

The 5.5W version additionally includes a 3.5-inch touchscreen for starting, pausing, and adjusting engraving parameters directly on the machine.
5. What software is compatible with the LONGER RAY5 Mini S?
The RAY5 Mini S is compatible with LaserGRBL (free, Windows), LightBurn (Windows, macOS, Linux with a 30-day free trial), and the MKSLaser mobile app (Android and iOS).

It supports common file formats including JPG, PNG, BMP, GIF, SVG, NC, GC, and G-code.

The machine can connect through Wi-Fi, USB cable, TF card offline mode, or the MKSLaser app. It works with Windows 7+, macOS, and Linux systems, and does not require proprietary software.
