Longer Ray5 40W Laser Engraver & Cutter – 44–48W 8-Beam FAC Diode Laser with Built-in Air Assist, 24,000mm/min Speed, 0.10×0.15mm Spot & Single-Pass 20mm Basswood / 0.15mm Steel Cutting for Wood, Acrylic & Metal

The batch of 50 custom wood name signs needs to ship in three days. Each one is 6mm walnut with fine-line engraving and a through-cut border. At 20W, that is a two-pass border cut and a long queue. At 40W, it is a single-pass cut at 24,000mm/min — the same job, in less than half the time. The Longer Ray5 40W compresses eight diode laser beams into a 0.10×0.15mm spot with 44–48W measured optical output — not nameplate watts, but the power that actually reaches the material. It cuts 20mm basswood in one pass and 0.15mm stainless steel cleanly where 20W machines require multiple attempts. Its built-in air pump engages with one touch and responds to LightBurn layer commands automatically. One computer can control multiple Ray5 40W units in parallel for production batches that run 7×24 hours. For makers and small businesses who need a machine that earns its place at full production speed, the Ray5 40W delivers the power, the precision, and the output per hour.

8-Beam FAC Compressed Laser – 44–48W Optical Power, 0.10×0.15mm Spot

The Ray5 40W compresses eight diode beams via FAC optics into a 0.10×0.15mm spot with 44–48W measured optical output — not nameplate watts, but actual light power at the material surface. Single-pass: 20mm basswood / 0.15mm stainless steel. Maximum capability: 30mm pine.

The 0.10×0.15mm spot enables 256-bit grayscale engraving with fine-line detail and high-contrast output on wood, leather, and coated metals. Multi-color engraving on stainless steel and coated metal surfaces is achievable via controlled oxidation at varying power and speed settings.

15mm Industrial Rail + 4-Pulley Y-Axis – 24,000mm/min Without Drift

At 24,000mm/min, the motion system is what separates clean output from drift artifacts. The Ray5 40W uses a 15mm industrial-grade X-axis linear rail and an upgraded four-pulley Y-axis that distributes belt tension evenly and minimizes backlash across the full 385×385mm work area.

The 32-bit ESP32 motherboard (240MHz) handles data throughput at high speed without the buffer stalls that cause speed artifacts on 8-bit controllers. Consistent engraving accuracy is maintained at maximum speed — faster production without sacrificing line quality or edge definition.

Built-in Air Assist + LightBurn Auto Control – Cleaner Cuts, No Manual Valve

The Ray5 40W integrates the air pump directly into the machine body — no external unit, no separate hose routing. One-touch activation from the 3.5-inch touchscreen starts airflow immediately. In LightBurn, air assist is configurable per layer — the machine automatically activates or deactivates based on cut parameters, with no manual intervention.

Result: cleaner acrylic edges, reduced char on wood, consistent depth control on thick materials. The laser head uses a replaceable protective lens and dust-proof hood to maintain output quality over extended production runs.

Multi-Machine Control + 7×24H Operation – Production at Scale

One computer controls multiple Ray5 40W units simultaneously — each unit runs its assigned job in parallel, maximizing throughput per operator. The machine is rated for 7×24H continuous operation, designed for the sustained duty cycle that production batch work requires.

Offline via Micro SD card or MKSLaser app (iOS/Android), machines run independently once a job is loaded. The upgraded Wi-Fi antenna maintains a stable wireless connection in workshop environments with interference from multiple devices or long distances from routers.

8-Layer Safety + FDA Class IV Compliance – Engineered for Confident Operation

Rated FDA Class IV / IEC Class 4 — the correct classification for an open-frame 40W diode laser. The 8-layer safety system covers: emergency stop / flame detection / motion protection / limit switches / auto homing after alarm / blue light filter lens / data loss protection / protective glasses included.

Class IV lasers require operator eye protection at all times during operation — glasses are included in the box. The 8-layer system manages the specific risks of high-power open-frame laser operation so that home workshops, classrooms, and professional studios can all use the Ray5 40W with confidence.
