TL;DR
The Ray7S 20W is the mixed-use version of Longer's enclosed laser: $529.99 for the Basic Set on Longer's store in October 2026, about $770 less than xTool's enclosed S1 20W. It cuts 6–8 mm basswood in one pass with air assist by our estimate, engraves at up to 600 mm/s with Klipper vibration compensation, and keeps the beam inside a Class 1 cabinet. The bed is 305 × 305 mm and the air pump is still an option at this power.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Regular cuts with the lid closed
By our estimate, 6–8 mm basswood in one pass with air assist inside a Class 1 cabinet.
About $770 under the xTool S1 20W
$529.99 in October 2026, against about $1,299 for xTool's enclosed 20W.
Our verdict
Ideal if you
The 20W Ray7S is the balanced enclosed choice: Class 1 safety, Klipper firmware and Wi-Fi, and enough power to cut the 3–6 mm plywood most products use, for far less than the established enclosed brands.
Skip if you
The 305 × 305 mm bed is small for signs, the air pump costs extra and the spot is wider than on the smaller modules. With no independent review yet, exhaust performance and cabinet build quality remain to be confirmed.
Pros
- Cuts 6–8 mm basswood in one pass with air assist by our estimate, enough for most enclosed box and sign work
- $529.99 in October 2026, about $770 less than xTool's enclosed S1 20W
- Klipper vibration compensation and 600 mm/s motion for faster, cleaner fills on larger engravings
Cons
- Air pump still optional at $529.99, although cutting is a main use at this power
- Bed shrinks to 305 × 305 mm with this module, against 498 × 319 mm on the xTool S1

Practical notes
Beginner notes
This profile is the 20W version of the Longer Ray7S. Pick it if you engrave and cut about equally and want the beam and most of the smoke kept inside a cabinet. Compare the other Ray7S versions with the chips above if you mostly engrave or cut thick stock daily. Budget for the optional air pump.
Pro tips
Buy the air pump with the machine: cutting without it inside a closed cabinet dirties the lens and the tinted lid quickly. Duct the exhaust outdoors. For batches, line up pieces with a jig on the bed, since the camera is an extra.

Common questions
How thick can the Ray7S 20W cut?
Longer does not publish per-version cutting figures. By our estimate, with air assist it cuts 6–8 mm basswood and 3–5 mm plywood in one pass, and about 10 mm basswood in several passes.
Ray7S 20W or xTool S1 20W?
The Ray7S 20W costs $529.99 against about $1,299 for the xTool S1 20W (October 2026). The S1 has a larger 498 × 319 mm bed, a mature software ecosystem and years of reviews; the Ray7S is far cheaper but new.
Ray7S 20W or Ray7S 40W?
The 40W costs $849.99, $320 more, and includes the air pump (October 2026). It roughly halves cut times and opens up 10 mm and thicker wood. Take the 20W if cutting is regular but not the main job.
Alternatives to the Longer Ray7S 20W
Machines in the same space, picked from our database by type, price, and score.
xTool · Diode · $1,299 – $2,599
The 20W S1 is the value pick in xTool's enclosed diode line: same cabinet and filters as the 40W, but less cut depth on thick wood. Buy this if safety matters and you mostly engrave.
Acmer · Diode · $765 – $1,658
The P3 24W puts a 24W diode module in Acmer's enclosed P3 cabinet: Class 1 lid with flame detection, CoreXY gantry at 800 mm/s, a camera covering the full 400 × 400 mm bed and 30 L/min air assist. Acmer rates it for 12 mm plywood and 8 mm black acrylic in one pass. At $765 for the Basic Pack (October 2026) it is one of the lowest-priced enclosed diode lasers with a camera; it suits makers who mostly engrave and cut thin stock.
xTool · Diode · $499 – $1,849
Launched May 2026, the M2 packs laser engraving, cutting, and integrated inkjet color printing into one enclosed desktop at $599. Built for everyday crafters and Etsy sellers who want color + laser without a pro CO₂ budget: not a metal-marking or production cutter.
