The existing laser marking control systems are mainly based on PC and PCI laser drivers. PC is used for editing marking information and extracting marking data. The rapid processing capacity of PC makes the laser making machine achieve faster processing speed. However, it cannot be used in the outdoors and bad situations. In older to make the laser marking system widely adapt to various environments, an embedded laser marking controller is developed. It is based on ARM9 and LINUX. It can be easily operated and can achieve wonderful marking.
