摘　　要：桌面级3D打印机步进电机通常采用梯形加减速控制,在高速打印时加减速过程易受到柔性冲击,影响打印质量。为解决上述问题,采用ARM架构的STM32F103微处理器,设计出一种基于该处理器的S曲线加减速控制方法,并与梯形加减速进行了对比实验。实验结果表明,采用设计的S曲线加减速控制方法后,3D打印机在高速打印时,加减速过程柔性冲击减小,打印质量提高。Trapezium acc/dec algorithm is generally applied in stepper control of desktop 3D printer, which affects printing quality in the acceleration and deceleration process at high speed printing because of flexible impact. In order to solve above problems, a S-curve acc/dec control method based on STM32F103 micro- processor is designed and the comparison experiment with the trapezoidal acc/dec control method is carried out. The experiment result shows that flexible impact is reduced when printing in the acceleration and decel- eration process at high speed and printing quality has been improved.
