The diode laser cuts and engraves a wide range of materials — including thick wood up to ~18 mm and dark acrylic up to ~15 mm in a single pass — without switching modules, and handles wood, acrylic, leather, plastics, and more for both creative and production workflows. A 19.6 x 12.5 in (50 x 32 cm) work area accommodates large pieces or batch-processing multiple smaller parts, and expands to 31.5 x 19.7 in (80 x 50 cm) with the optional R7 Pro conveyor feeder.\u003c\/p\u003e\n    \u003cp\u003eA built-in 16 MP HD camera with 0.5 mm accuracy handles alignment and work-area preview, and pairs with AI-powered software to automatically position designs for batch engraving. The Kraft 40 W includes automatic resume, restoring the exact laser head position and job progress after a power outage, and a two-in-one air pump that functions as both a standard air assist for cleaner cuts and fewer burn marks, and a flame-extinguishing safety system that activates automatically if the machine's sensors detect fire.\u003c\/p\u003e\n    \u003cp\u003eSafety features include a certified Class 1 enclosure, automatic fire extinguisher, dual emergency stop buttons, open-lid detection, and tilt detection, all backed by IEC 60825-1 Class 1 laser safety certification. The machine runs on AtomStack Studio — free software supporting iOS, Android, Windows, and macOS with DXF, JPG, PNG, BMP, SVG, and GIF file import — and is also compatible with LightBurn and LaserGRBL. The Kraft 40 W ships as a complete starter setup with a honeycomb panel, air assist accessory, focusing block and tools, USB drive and safety USB key, calibration card, and power cable, ready to begin engraving out of the box.\u003c\/p\u003e\n \n\n\n\u003cbr style=\"clear:both;\"\u003e\n\n\u003chr\u003e\n\n\u003cdiv class=\"one-half-column-left\"\u003e\n    \u003cimg
