Arduino UNO R3、CNC shield V3、A4988(2个)、Micro Servo 9g、光驱(2个)、12V1A电源适配器、结构件材料(自制)、线材、热熔胶等。
CNC shield V3 直接买这个扩展板对没基础的maker来说,接线会方便很多,不需要用面包板或洞洞板焊接线。购买时要注意买“跳帽”,这个也不能忘记。
Arduino CNC shield原理图:
A4988 购买时,一般都会配有散热片,给A4988上的芯片散热。
Micro Servo 9g 这个要注意,常见的有180度和360度两种旋转的舵机,我们要买180度的舵机。
光驱 因为光驱上有安装好的微型步进电机、光杆和滑台,我们可以直接用它作为一个方向的运动平台。
Arduino Uno + CNC Shield V3 + GRBL v1.1固件.
CNC shield直接扣到Arduino UNO板上。
将2个A4988扣到X、Y插座上,注意看图中它们的方向。散热片直接贴再芯片上。将步进电机引出的四根线连接到A4988旁的引针上。步进电机四个引脚分别是两个绕组的两端,两两相连。我们使用万用表的蜂鸣器测出互相连接的两个引脚。相连的两个引脚接到控制板上相邻的两个针脚上就行。
CD/DVD 机械部件:通常光驱的电机是18度(每圈20步),行程是3毫米。所以当驱动设置在1/32细分时,GRBL的$100参数是(20 * 32) / 3 = 213.33 (步/毫米). 搜索关键词:“DIY光驱丝杆滑台”

SourceRabbit GCode Sender is a GRBL compatible, cross platform CNC control software.
It features a highly optimized and asynchronous (event-driven) UI and USB-to-Serial communication and can be also used on computers with small amount of RAM and CPU.

LaserGRBL is a Windows GUI for GRBL. Unlike other GUI LaserGRBL it is specifically developed for use with laser cutter and engraver. In order to use all of LaserGRBL feature, your engraver must supports laser power modulation through gcode “S” command. LaserGRBL is compatible with Grbl v0.9 and Grbl v1.1

CuraEngine是一个强大,快速且强大的引擎,用于将3D模型处理为Ultimaker和其他基于GCode的3D打印机的3D打印指令。它是大型开源项目“ Cura”的一部分。https://ultimaker.com/en/products/cura-software
CuraEngine
The CuraEngine is a C++ console application for 3D printing GCode generation. It has been made as a better and faster alternative to the old Skeinforge engine.
The CuraEngine is pure C++ and uses Clipper from http://www.angusj.com/delphi/clipper.php Furthermore it depends on libArcus by Ultimaker, which can be found at http://github.com/Ultimaker/libArcus
This is just a console application for GCode generation. For a full graphical application look at https://github.com/Ultimaker/Cura which is the graphical frontend for CuraEngine.
The CuraEngine can be used seperately or in other applications. Feel free to add it to your application. But please take note of the License.

计算每毫米的脉冲数
光驱特点:每步18度(一圈20步),丝杆直径一般为3mm,丝杆螺距为3mm,也就是步进电机每转一圈,移动距离为3毫米,
咱主要修改“脉冲数”脉冲/mm这个参数
首先你必须知道你买的滑台的以下参数
