Introduction
NEJE 2, 3, 4, and 5 series laser engravers are popular among hobbyists and small businesses for their affordability, compact design, and solid performance on wood, leather, acrylic, and more. These diode laser machines run on GRBL firmware and are fully compatible with two of the most widely used laser control programs: LightBurn (feature-rich and user-friendly) and LaserGRBL (free and lightweight).
