Image to GCode

Convert jpg, jpeg, png, gif to gcode with NodeJS.

- Generate GCode with absolute coordinates, finds a black pixel if you follow the trail.
- This version is faster previous versions.
- Find the shortest path to the next black pixel.

``bash
$ npm install img2gcode
`

Quick Start

Depending on the configuration between tool and image height generates better code.

`Javascript
var img2gcode = require("img2gcode");

img2gcode
.start({
// It is mm
toolDiameter: 2,
scaleAxes: 700,
deepStep: -1,
whiteZ: 0,
blackZ: -2,
safeZ: 2,
dirImg: __dirname + '/img-and-gcode/test.jpeg'
}).then((data) => {
console.log(data.config);
console.log(data.dirgcode);
});
`

$3

- toolDiameter (number) Tool diameter. default: 1
- sensitivity (number) Intensity sensitivity. 0 to 1. default: 0.95
- scaleAxes (number) Image height in mm. default: image.height equal mm
- deepStep (number) Depth per pass. default: -1
- invest { x: (boolean), y: (boolean) } default: {x: false, y: true}.
- dirImg (string) Image path, accepts JPEG JPG PNG GIF formats.
- whiteZ (number) White pixels. default: 0
- blackZ (number) Maximum depth (Black pixels).
- safeZ (number) Safe distance.
- info (string) Displays information. ["none" | "console" | "emitter"] default: none
- feedrate { work: (number), idle: (number) } Only the corresponding line is added. default: ''
- laser { commandPowerOn: (string), commandPowerOff: (string) } Is you set this options, Z command is will be ignore

$3

Only if Options.info it is "emitter"

- log Displays information.
- tick Percentage of black pixels processed. 0 (0%) to 1 (100%).
- error Displays error.
- complete Emits at the end with "then".

$3

- then This function is called to finish saving the file GCode and receives an object: { config , dirgcode }

$3

`javascript
var img2gcode = require("img2gcode");
var ProgressBar = require("progress"); // npm install progress
var bar = new ProgressBar("Analyze: [:bar] :percent :etas", { total: 100 });

img2gcode
.start({
// It is mm
toolDiameter: 1,
scaleAxes: 700,
deepStep: -1,
feedrate: { work: 1200, idle: 3000 },
whiteZ: 0,
blackZ: -2,
safeZ: 1,
info: "emitter", // "none" or "console" or "emitter"
dirImg: __dirname + "/img-and-gcode/test.png",
})
.on("log", (str) => {
console.log(str);
})
.on("tick", (perc) => {
bar.update(perc);
})
.then((data) => {
console.log(data.dirgcode);
});
`

Config for laser options

`javascript
const options = {
// It is mm
toolDiameter: 3,
sensitivity: 0.9,
scaleAxes: 128,
feedrate: { work: 1200, idle: 3000 },
deepStep: -1,
laser: {
commandPowerOn: "M04",
commandPowerOff: "M05",
},
whiteZ: 0,
blackZ: -3,
safeZ: 1,
info: "emitter",
dirImg: path.normalize(__dirname + imgFile),
};

I hope someone else will serve (MIT).
