Laser engravers are getting smarter every year. The latest models allow WiFi/Bluetooth connectivity and app control. Take the Genmitsu Jinsoku LC-40 for instance: it is an app controlled laser engraver with a fixed focus 5.5W laser and focusing tool. It can cut through 4mm of plywood in one pass.
The LC-40 has a built-in motion sensor for safe operation. You can use it for engraving cardboard, plywood, cloth, leather, stone, glass, stainless steel, and a whole lot more. It supports LightBurn & LaserGRBL.
