When you are standing in the workshop trying to decide between an enclosed, heavy-duty workspace and an open-frame powerhouse for cutting thick stock, the sheer number of 40W diode options available in 2026 can feel overwhelming. We have spent the last few weeks putting both the xTool S1 40W and the LONGER RAY5 40W through rigorous testing on everything from delicate tumblers to dense hardwoods, pushing their limits to see how they actually perform under daily shop conditions.
Choosing the right machine fundamentally changes how you approach your workflow, especially if you deal with large panels or specialized cylindrical items regularly. While both deliver the robust 40W optical power required for serious cutting and engraving, their physical footprints and interface designs cater to completely different types of makers. Let us break down exactly how these two heavy hitters compare so you can make an informed choice for your setup.

Where A Wins
- Enclosed Safety and Structure: The xTool S1 features an enclosed housing design that helps contain smoke and laser exposure, making it ideal for shared or indoor spaces where open beams require strict caution.
- Specialized Rotary Bundle Integration: Out-of-the-box support for cylindrical items like tumblers makes it vastly superior for makers focusing heavily on drinkware and curved merchandise.
- Generous Bed Dimensions: Its 23.93″ x 15.16″ bed size provides a spacious rectangular workspace for handling large wood panels and bigger projects.
Where B Wins
- Impressive Acrylic Cutting: The LONGER RAY5 cuts through up to 30mm acrylic, offering exceptional depth performance for thick clear materials and dimensional signage.
- Standalone Usability: Equipped with a 3.5″ touchscreen and 32-bit control board, it allows for smooth offline operation without requiring a computer constantly tethered to the unit.
- Advanced Visual Flexibility: It supports 256-color engraving, giving users unique shading control for detailed photographic and artistic imagery on various substrates.
Real-World Use: Which One Fits You
The Custom Drinkware Business
If your main revenue stream relies on personalising hundreds of cylindrical items, the xTool S1 is the clear winner. Its dedicated rotary bundle integration makes swapping from flat wood sheets to tumblers completely seamless, saving you precious hours in setup and alignment.
The Thick-Stock Sign Maker
Makers who frequently process heavy acrylic up to 30mm thick will find the LONGER RAY5 indispensable. The high-power output combined with integrated air assist ensures clean, melted-edge cuts on massive dimension stock without stalling your workflow.
The High-Speed Production Shop
For workshops needing fast throughput on standardized wood panels using an open-frame layout, the LONGER RAY5 shines. Its 24000mm/min speed and onboard 3.5″ touchscreen let you load jobs quickly via standalone controls and churn out inventory efficiently.
Price and Value
When evaluating value, both units are listed with a “Check price” status rather than fixed figures, meaning exact dollar differences fluctuate depending on current retail promotions and bundle additions like the xTool rotary package. However, the true value depends entirely on your specific production demands: the xTool S1 justifies its investment through its enclosed system and specialized bundle accessories tailored for tumbler businesses, while the LONGER RAY5 delivers exceptional hardware value through heavy acrylic cutting performance, built-in air assist, and a responsive touchscreen control board.
Final Recommendation
Choose the xTool S1 40W if your primary focus is on an enclosed system optimized for big projects and tumbler engraving via its comprehensive rotary bundle. The only condition under which you should pick the LONGER RAY5 40W instead is if you require standalone 3.5″ touchscreen operation, open-frame flexibility, and the ability to cut up to 30mm acrylic stock.
FAQ
Do both machines offer a true 40W optical output?
Yes, both the xTool S1 and the LONGER RAY5 utilize high-power 40W laser modules designed to cut through dense materials efficiently. They provide the necessary energy density to tackle thick wood, metal marking, and heavy substrates.
Can I run the LONGER RAY5 without a computer?
Absolutely. The LONGER RAY5 features a built-in 3.5″ touchscreen and 32-bit control architecture that allows you to manage and run jobs directly from the machine interface. This standalone capability keeps your computer free during long engraving runs.
How does the xTool S1 handle cylindrical objects?
The xTool S1 comes configured in a rotary bundle that is explicitly tailored for engraving tumblers and other cylindrical items. This setup seamlessly translates rotational movement for accurate wraps without distortion.
Is air assist included with these engravers?
The LONGER RAY5 explicitly includes air assist to clear out debris and smoke for cleaner cuts, especially through thick materials like 30mm acrylic. Specifications for air integration on the xTool S1 vary depending on the chosen configuration bundle.
