 Warning: | Don't mill printed circuit boards made of "glass fiber epoxy resin" (FR4). Small pieces of milled glass fiber should not be inhaled. It may cause health problems. |
1. Designing the PCB
There are several ways for designing PCB. For example you can use the following softwares:
- Fritzing (easy to use) https://fritzing.org/
- Kicad (more professional) https://www.kicad.org/
Lets start with Fritzing.
That looks already quite good. After you finished the PCBs you have to export it as a "Extender Gerber (RS-274X)"-Format! Select the folder where you would like to save it.
2. Generating the G-code
In this step you have to generate G-code with the Gerber files. G-code or sometimes called nc-code (numeric controll code) tells the CNC mill when to turn on the spindle or to which position it should move.
We will use FlatCam (http://flatcam.org/) to generate the G-Code.
