LONGER Ray5 MiniS 3.5W Laser Engraver 130×140mm 12000mm/min 0.04mm Spot

Ready-to-use desktop engraver

The LONGER Ray5 MiniS 3.5W Laser Engraver arrives fully pre-assembled with an integrated protective enclosure, so it can start engraving wood, acrylic, leather and plastic immediately. A 32-bit motherboard drives the diode laser at up to 12000 mm/min across a 130×140 mm work area. The 0.04 mm compressed spot delivers fine detail for hobbyists and small-batch makers who want a plug-and-play solution.

Fits a benchtop with minimal extras

The enclosed acrylic cover, door detection and emergency stop let the machine run safely on a desk without a separate ventilation cabinet or external interlock wiring. WiFi and offline modes mean a host PC is optional; LightBurn, LaserGRBL and LaserBurn handle job preparation on Windows, macOS or mobile devices. Limit switches on X and Y axes home the head automatically, freeing the operator from manual alignment steps.

Steady output during long jobs

Fixed-focus optics with a dovetail height plate keep the 450 nm beam at its 0.04×0.04 mm spot size over extended runs, while the aluminum frame resists vibration at full speed. The safety system pauses the laser instantly if the door opens, then resumes from the interruption point when closed, preventing wasted material on multi-hour engravings.
