6 A% W) |7 k0 `# [: _2 X! I1 S 以前制作过CNC雕刻机,是用MACH3作为上位机控制,硬件是采用PC接并口输出脉冲和方向使能信号经过隔离驱动步进电机驱动器,步进电机驱动是采用TB6560芯片控制。最后就接到步进电机。机械是用铝合金制作,主要部件有三个1605的滚珠丝杠,多个运动滑块等制作。用这台DIY CNC雕刻机可以雕刻木头塑料等东西。当时没有一直玩下去,现在发现网上有用单片机制作的雕刻机挺精巧的现在分享给大家。
' _ n( o6 Q; `* _( w GRBL CNC 3D打印机,这就是我说的可以用单片机来控制的3D打印机,我先照着百度科普下grbl,Grbl是性能高,成本低,基于并口运动控制,用于CNC雕刻。它可以运行在Vanilla Arduino (Duemillanove/Uno) 只要它配备了Atmega 328型芯片。 控制器由C编写并优化,利用了AVR 芯片的每一个灵巧特性来实现精确时序和异步控制。它可以保持超过30kHz的稳定、无偏差的控制脉冲 它接受标准的G代码而且通过了数个CAM工具的输出测试。弧形、圆形和螺旋的运动都可以像其他一些基本G代码命令一样完美支持。函数和变量目前并不支持,但是会作为预处理器包含在将来发布的版本之中。 Grbl 包含完整的前瞻性加速度控制。它意味着控制器将提前16到20个运动来规划运行速度,以实现平稳的加速和无冲击的转弯。Grbl是性能高,成本低,基于并口运动控制,用于CNC雕刻。它可以运行在Vanilla Arduino (Duemillanove/Uno) 只要它配备了Atmega 328型芯片。 控制器由C编写并优化,利用了AVR 芯片的每一个灵巧特性来实现精确时序和异步控制。它可以保持超过30kHz的稳定、无偏差的控制脉冲 它接受标准的G代码而且通过了数个CAM工具的输出测试。弧形、圆形和螺旋的运动都可以像其他一些基本G代码命令一样完美支持。函数和变量目前并不支持,但是会作为预处理器包含在将来发布的版本之中。 Grbl 包含完整的前瞻性加速度控制。它意味着控制器将提前16到20个运动来规划运行速度,以实现平稳的加速和无冲击的转弯。很棒吧!开始玩起。![]()
