摘　　要：简要介绍了所设计的打印机控制系统。重点研究了选用的Xaar128压电式喷头及其驱动信号时序关系,阐述了驱动信号实现模块图及具体流程。在此基础上利用LPM例化的双FIFO实现喷头数据暂存和位宽处理,并阐述了在三维打印中利用电机编码器位置脉冲来直接触发喷头喷射的优点。A controlling system designed for 3D printer is hriefly introduced. The Xaar-128 piezoelectric print head and its drive sequence scheduling are studied and the module and procedure to achieve the drive signals are expounded as follow. On that basis two FIFOs instantiated in LPM are used to store the print data and manage the bit wide of the data. Finally, it is explained that the advantages of utilizing position pulse signals of motor coder to trig directly the print head for ietting.
