This project aims to provide a JSON-backed reference to the G & M codes associated with CNC mills, lathes, 3D printers and more. This project was created to be consumed by our VSCode G-Code Syntax extension for hover information, but we think it can be of use for many different applications.

Since this is still in very early stages of development, here are the goals outlined for the project:

• JSON Files
  • Provide a comprehensive & accurate source of information on G & M codes for CNC Mills & Lathes, as well as 3D Printers.
• Provide an API to be consumed by Typescript / Javascript / Node applications to retrieve the information.
• Ability to generate full pages of information in HTML or Markdown.
• Act as a single reseource via GitHub pages for all to read the documentation
• Provide a simple interface for contributors to add / modify the reference JSON.

To install the latest version:

npm install @appliedengdesign/gcode-reference --save

Try it in the Node.js REPL :)

Javascript:

// Import Everything ESM/Typescript style
import * as GRef from 'gcode-reference';
// OR
const GRef = require('gcode-reference');

const gref = new GReference();
// OR
// initialize with a machine type
const gref = new GReference('mill');
// OR
// initalize with a machine type and variant
const gref = new GReference('mill', 'mazak');

// Get Complete G-Code Object
const gcode = gref.get('G1');

// Get All Codes
const gcode = gref.getAllCodes(CodeTypes.G);

// Get Short Description
const shortDesc = gref.getShortDesc('G1');

// Get Full Description
const desc = gref.getDesc('G1');

// Get Current Machine Type
const type = gref.getType();

// Set Machine Type (Will rebuild reference)
gref.setType(GRef.MachineTypes.Mill);

// Set or Remove a Variant
gref.setVariant(Gref.MachineTypes.Mazak);
gref.removeVariant();

// Check if there is a variant
gref.isVariant();

// Get Parameters for a G/M Code
gref.getParams('G84');

// MARKDOWN GENERATION

// Get Code as Markdown
const codeMarkdown = gref.getCodeAsMarkdown('G1');

// Get All Codes formatted in Markdown
const codesMarkdown = gref.getAllCodesAsMarkdown('gcode');

// HTML GENERATION

// Get Code as HTML (complete w/ head/meta)
const codeHTML = gref.getCodeAsHTML('G1', false);

// Get Code as HTML (partial) - default if true/false not included
const codeHTML = gref.getCodeAsHTML('G1');

// Get All Codes as HTML (partial by default as well)
const codeHTML = gref.getAllCodesAsHTML('G1', false);

// You can also import the types separately / individually when using Typescript

} from 'gcode-reference';

Supported machine types are edm, mill, lathe, laser, printer or swiss. You can select the machine type using the string variant or use the enum MachineTypes.

The current supported variants are amada, brother, centroid, citizen, doosan, fadal, fanuc, haas, hurco, mach3, mazak, milltrs, mitsu, okuma, snpmaker and tormach. These are also exposed under the enum Variants.

For more information on creating more variants or requesting them, please check out our Contributing page.

The schema used for the JSON data is published in the repo cnccodes-json-schema and was created specifically for this project.

If you find any bugs or issues with the package, please create a new GitHub issue.

We need people to help add more G & M codes to the various machine tool bases as well as adding variants.

For information on contributing, please refer to the CONTRIBUTING doc for information on how to add to this project.
