NPM

Install

npm install --save gcode-interpreter

Usage

const Interpreter = require('gcode-interpreter');

const Runner = function() {
    const handlers = {
        'G0': (params) => {
            console.log('G0', params);
        },
        'G1': (params) => {
            console.log('G1', params);
        }
    };

    return new Interpreter({
        handlers: handlers,
        defaultHandler: (cmd, params) => {
        }
    });
};

const runner = new Runner()
const file = 'example.nc';
const stream = fs.createReadStream(file, { encoding: 'utf8' });
const content = fs.readFileSync(file, 'utf8');

// Load G-code from stream
runner.loadFromStream(stream, function(err, data) {
});

// loadFromFile
runner.loadFromFile(file, function(err, data) {
});

// Synchronous version of loadFromFile
runner.loadFromFileSync(file);

// loadFromString
const content = fs.readFileSync(file, 'utf8');
runner.loadFromString(content, function(err, data) {
});

// Synchronous version of loadFromString
runner.loadFromStringSync(content);

Examples

Run this example with babel-node:

import Interpreter from 'gcode-interpreter';

const GCODE = [
    'N1 G17 G20 G90 G94 G54',
    'N2 G0 Z0.25',
    'N3 X-0.5 Y0.',
    'N4 Z0.1',
    'N5 G01 Z0. F5.',
    'N6 G02 X0. Y0.5 I0.5 J0. F2.5',
    'N7 X0.5 Y0. I0. J-0.5',
    'N8 X0. Y-0.5 I-0.5 J0.',
    'N9 X-0.5 Y0. I0. J0.5',
    'N10 G01 Z0.1 F5.',
    'N11 G00 X0. Y0. Z0.25'
].join('\n');

class Toolpath {
    handlers = {
        'G0': (params) => {
            console.log('G0', params);
        },
        'G1': (params) => {
            console.log('G1', params);
        },
        'G2': (params) => {
            console.log('G2', params);
        },
        'G17': (params) => {
            console.log('G17');
        },
        'G20': (params) => {
            console.log('G20');
        },
        'G90': (params) => {
            console.log('G90');
        },
        'G94': (params) => {
            console.log('G94');
        },
        'G54': (params) => {
            console.log('G54');
        }
    };

    constructor(options) {
        options = options || {};

        return new Interpreter({
            handlers: this.handlers,
            defaultHandler: (cmd, params) => {
            }
        });
    }
}

const toolpath = new Toolpath();

toolpath
    .loadFromString(GCODE, (err, results) => {
        if (err) {
            console.error(err);
            return;
        }
    })
    .on('data', (data) => {
        // 'data' event listener
    })
    .on('end', (results) => {
        // 'end' event listener
    });

and you will see the output as below:

G17
G20
G90
G94
G54
G0 { Z: 0.25 }
G0 { X: -0.5, Y: 0 }
G0 { Z: 0.1 }
G1 { Z: 0, F: 5 }
G2 { X: 0, Y: 0.5, I: 0.5, J: 0, F: 2.5 }
G2 { X: 0.5, Y: 0, I: 0, J: -0.5 }
G2 { X: 0, Y: -0.5, I: -0.5, J: 0 }
G2 { X: -0.5, Y: 0, I: 0, J: 0.5 }
G1 { Z: 0.1, F: 5 }
G0 { X: 0, Y: 0, Z: 0.25 }
