A simple library for generating G-Code in Javascript

Installation

GCode is available through the npm registry:

$ npm install @oneisland/gcode

Usage

After installing GCode you can use the module like so:

example-usage.js

// Import the library
import { GCode } from '@oneisland/gcode';

// Create a new code section
const code = new GCode({

  // Define the script name
  name: '123',

  // Define the scale to use (default is mm)
  units: 'cm',
  
  // Define the starting x and y position
  start: [0, 0],

  // Set the clearance height to 10cm
  clearance: 10,
});

// Start the spindle
code.startSpindle();

// Start the coolant
code.startCoolant();

// Drop the mill to the bottom of the board
code.dropMill();

// Cut lengthways 65.5cm
code.feedLinear([0, 65.5]);

// Cut sideways 23.4cm
code.feedLinear([23.4, 65.5]);

// Cut diagonally to a point (12.28cm sideways, midpoint lengthways)
code.feedLinear([12.8, (65.5 / 2)]);

// Cut back to the start lengthways
code.feedLinear([12.8, 0])

// Cut back to the starting point
code.feedLinear([0, 0]);

// Output the code to console
console.log(String(code));

Execute the example code:

$ node example-usage.js
