摘要
步进电机作为3D打印机上的主要执行元件,其运行速度对打印效率有着重要的影响。现有的定细分数3D打印步进电机控制方法在追求高精度打印的同时往往会牺牲打印速度,为了解决这一问题,提出了一种变细分数的3D打印步进电机控制方法,即大距离范围内采用低细分数,以提升运行速度,在小距离范围内采用高细分数,以保证打印精度。搭建了仿真模型和实验系统,结果表明:提出的变细分数控制方法在保证打印精度的同时提高了打印速度,验证了该方法的可行性与有效性。
Stepper motor is the main executive component of 3D printer,and its running speed has important influence on printing efficiency. The existing method of controlling 3D stepping motor with fixed fraction is always sacrificing the printing speed while pursuing high precision printing. In order to solve this problem,a method for controlling 3D printer stepper motor with variable subdivision was proposed,that is,in large distance range low variable subdivision method was adopt to improve the running speed,and in short distance range high variable subdivision method was adopted to guarantee printing accuracy. A simulation model and experimental system were built,the simulation and experimental results show that proposed control method improve the printing precision and the printing speed,the proposed method is feasible and effective.
