Need a large-bed laser that doesn't tie you to a computer? The WOXCKER JL7 10W delivers a 400×400 mm work area and cuts 20 mm wood and 10 mm black acrylic, with a triple-motor system and steel-axis wheels for smooth, durable movement and a 0.08×0.08 mm focus. A built-in gyroscope and 3-way limit switches add protection, and you can engrave fully offline from a TF card — or via mobile app, USB and WiFi, with no PC required. LightBurn and LaserGRBL are both supported. If you want big-bed cutting with true offline convenience, the JL7 10W is the pick.
