The LMCSPI is a specialized industrial control card engineered for high-precision laser marking applications. It serves as the core processing unit that interfaces between the control software and the laser system’s hardware. Specifically designed to work seamlessly with SPI G3 series fiber lasers and standard galvanometer scanheads, this board ensures reliable and accurate control over the marking process. Featuring a robust design with a central BGA processor, it provides dedicated connectors for the scanhead (DB25), SPI laser source (D-Sub), and motor power, making it an ideal replacement or core component for building or repairing compatible laser marking machines. The inclusion of a ‘Mark-on-the-fly’ interface (CON9) also enables advanced capabilities for marking objects on a moving production line.
