MIDILLI G-Code Generator for CNC Routers

Quick Usage

[Top]

Download the ZIP file and extract to a location. Copy the Example JSON file below and save it as test.json using a simple text editor. To keep the things simple, save it at the same location as the executable.

Example JSON file

The following file generates all six sides for MyPart, placing one hole and one rectangle cutout on the Top side. The top size of the box is 5×5 cm and the components are placed at (x = 1, y = 1) and (x = 3, y = 3) respectively. The visible sizes of the components are the same as drill sizes.

{
	"Generic": {
		"width": 5.0,
		"length": 5.0
	},
	"MyPart_Top": {
		"myRoundComponent#1": {
			"location_x": 1,
			"location_y": 1,
			"drill_diameter": 1,
			"call_name": "Hello",
            "visible_diameter": 1,
			"rotation": 0
		},
		"myRectangleComponent#1": {
			"location_x": 3,
			"location_y": 3,
			"drill_width": 2,
			"drill_length": 1,
			"call_name": "MIDILLI",
			"visible_width" : 2,
			"visible_length" : 1,
			"rotation": 0
		}
	},
	"MyPart_Bottom": {

	},
	"MyPart_Back": {
		
	},
	"MyPart_Front": {

	},
	"MyPart_Left": {

	},
	"MyPart_Right": {

	}
}

Depending on the command-line options, the other sides of the part will be created using different sizing. Read Coordinate system and effect of sizing parameters for more on different results of the arguments.

Note: JSON syntax is very strict. Ensure that the last line before each '}' does not end with a comma, while all other lines should. Use an online validation tool to confirm correctness.

Command line

Assuming that the JSON file is stored at the same location as the executable file, open a command window (Command Prompt, or PowerShell), then execute the following command:

.\GCodeGenerator.exe --json-file .\test.json --output-directory . --material-thickness 3 --cut-depth-per-pass 1 --box-height-3d 30

You will be provided with an output showing the current settings as following:

~~~~~ Settings ~~~~~
Outer sizing enabled: No
Components enabled: Yes
Side outline enabled: Yes
Screw diameter top in mm: 0
Screw diameter bottom in mm: 0
Screw head diameter in mm: 0
Screw head height in mm: 0
Screw extra margin in mm: 0
Recess depth in mm: 0
Feedrate on X-axis: 200
Feedrate on Y-axis: 200
Feedrate on Z-axis: 100
Bit shape: straight
Bit diameter in mm: 0
Material thickness in mm: 3
Depth per pass in mm: 1
Box height in 3D in mm: 30
Cut depth per pass in mm: 1
Simulation enabled: No

Each setting on the console output can be customized with command line arguments.

After completion, 6 files starting with MyPart_ and ending with .nc will be visible under test directory. Opening MyPart_Top.nc in a program which can parse G-Codes should display a view similar to the following:

Execution of the G-Code will move at 200 feedrate and drill 1 millimeter (mm) at each pass at 100 feedrate to open the holes for the components of a material with the thickness of 3 mm. At the end, it will cut along the outline of the Top to separate it from the larger material. For more customization, read the Detailed usage section.
