### 6. CNC drilling and milling
To drill holes and mill board outlines, `gcode` files need to be generated. Load them to `gSender` and drill and mill the board on a CNC router.
1. To generate `gcode` files from `gerber` format, look in the [examples/CNC_mill_drill_from_gerber](./examples/CNC_mill_drill_from_gerber/Readme.md)
2. To generate `gcode` files from `KiCad` format, look in the [examples/CNC_mill_drill_from_KiCad](./examples/CNC_mill_drill_from_KiCad/Readme.md)

The script will generate gerber files in the `output` directory and then convert them into `ngc` format in the `gcode` directory.
Load the `ngc` file to `gSender` program for the fabrication.
The script will first generate gerber files in the `output` directory and then convert them into `ngc` format in the `gcode` directory.
Launch the `gSender` program.
* Load the `drill.ngc` file for drilling holes.
* Load the `outline.ngc` file for milling the board outlines.
* Load the `back.ngc` file if you want to mill the isolation traces.

First, generate gerber files. These are the same used to order from a vendor. There are no specific settings, just:
KiCad PCB Editor → File → Fabrication Outputs → Gerbers
* Set "Output directory" to "gerbers/"
* Select only B.Cu (bottom copper)
* Select B.Cu (bottom copper) and Edge_Cuts (board outlines)
* Click Plot
* Then Generate Drill Files → Generate
