Performance: How Does It Actually Perform?
Engraving Speed and Quality
I was genuinely impressed by both the engraving speed and output quality of the Longer Ray5 20W laser engraver during testing. Moreover, at a maximum speed of 10,000 mm/min, this machine completes projects significantly faster than most competing diode laser engravers in the same price bracket.
Furthermore, the engraving quality on wood is particularly outstanding, producing crisp, fine details that remain clear even when examined closely. Additionally, the compressed-spot technology used in the laser module produces a tighter, more precise focal point than older diode laser designs, which translates directly into sharper engraving results across all materials.
Cutting Performance
As a 20W diode laser engraver, it delivers genuinely solid cutting performance on wood and acrylic. Moreover, 3mm plywood cuts cleanly in a single pass at moderate speeds — which is exactly what you want for craft projects, custom signs, and decorative items.
Furthermore, thicker materials like 5mm pine wood require multiple passes, but the results remain clean and accurate when using proper settings in LightBurn software. Consequently, the Longer Ray5 20W handles the vast majority of typical home and small business cutting projects without difficulty.
Longer Ray5 20W vs Longer Ray5 10W — Which Should You Choose?
Many buyers find themselves deciding between the Longer laser engraver Ray5 10W and the more powerful 20W version. Moreover, here is my honest and straightforward comparison to help you make the right decision:
| Feature | Ray5 10W | Ray5 20W |
|---|---|---|
| Optical Power | 10W | 20W |
| Cutting Depth | Limited | Significantly better |
| Engraving Speed | Good | Faster |
| Metal Engraving | Limited | Better performance |
| Price | Lower | Higher |
| Best For | Light projects | Serious cutting and engraving |
Furthermore, my honest recommendation is simple — if your budget allows, choose the 20W version every single time. Moreover, the additional power offers significantly more material options and yields noticeably better results across virtually every project type.
Software Compatibility and Setup
LightBurn — The Recommended Choice
The Longer Ray5 20W laser engraver works beautifully with LightBurn — which is widely considered the gold standard software for diode laser machines. Moreover, LightBurn offers intuitive design tools, precise speed and power controls, and an excellent library of material settings that take much of the guesswork out of finding the right parameters.
Furthermore, LightBurn is a paid software but offers a free trial period, and most serious laser engraver users consider it worth every penny of the purchase price.
LaserGRBL — The Free Alternative
Additionally, LaserGRBL offers free software for users who prefer not to purchase LightBurn. Moreover, it is less feature-rich than LightBurn but handles basic engraving tasks very capably. Furthermore, it is particularly popular with beginners who are still learning the fundamentals of laser engraving before investing in premium software.
