Developers

Want to help? Apart from self found bugfix and enhancement PRs I would really love help with the Milestones - We are always happy for pull requests!

Coding style: Keep it such that amateurs can still help with the code. Less this/that and obscurity, and more easy reading, easy debugging code (look at the existing style to get a feel) - LaserWeb is a very inclusive project - any firmware, any skill level, any OS really - all welcome. But lets try to keep this Javascript as far as possible, and try to keep it such that even novice coders can come in and contribute to our code with ease

Community:

Looking for a nice community of Laser users who like hacking their machines? Join the K40 LASER CUTTING ENGRAVING MACHINE Community on Google Plus - its their inspiration you have to thank for me creating LaserWeb in the first place. Join over on https://plus.google.com/communities/118113483589382049502

Another great community resource is the Google group Opensource Laser at https://groups.google.com/forum/#!forum/opensource-laser

Serial baud rate

Your Marlin/Smoothie/Grbl based lasercutter should be configured to use a baud rate of 115200, you can set that in Configuration.h for Marlin.
If you are running a default Lasersaur, its default baud rate is 57600. I would advise changing that in firmware and recompiling (edit config.c in ./src/ and use Lasaurapp to build and upload)

You can also modify the LaserWeb config.js to change the baud speed to match your machine

NB: MAKE SURE THE BOARD IS PLUGGED IN BEFORE STARTING LASERWEB. LaserWeb connects to all serial ports on startup (not like pronterface where you connect manually) - this allows us to be simultaneously connected to several machines, the dropdown in the UI allows you to switch between them at will (but that switches the interaction / UI - it does connect/disconnect (; - good since it allows jobs to continue on one machine while you jog/setup another machine)

Installation Instructions (NB See Access instructions below the install instructions)

Windows Procedure courtery of @fuininthefalls (Anthony Bolgar)

On Windows 7 and above, please use the following instructions. We are assuming from a vanilla Windows installation so your mileage may vary depending on things you already have installed. If you find conflicts, please let us know via a GitHub Issue

Step by step install for windows users:

Prerequisites:

1. Download and install Node.js version node-v0.12.7 from https://nodejs.org/download/release/v0.12.7/
2. Install Google Chrome if not already installed
3. Download and install Git For Windows from https://git-scm.com/download/win

LaserWeb install instructions:

1.  Start a windows command prompt by typing "cmd" in windows search (do not type the quotes)
2.	Type "cd\" (do not type the quotes)
3.	Type "git clone https://github.com/openhardwarecoza/LaserWeb.git" (do not type the quotes)
4.  Type "cd LaserWeb" (do not type the quotes)
5.  Type "npm install" (do not type the quotes)

The software is now installed.

To start the software:

1.	Start a windows command prompt by typing "cmd" in windows search (do not type the quotes) 
2.	In the command prompt window type "cd\laserweb" at the command prompt (do not type the quotes)
3.	In the command prompt window type "node server" at the command prompt (do not type the quotes)
4.	Start the google Chrome web browser (software is only tested to work with Chrome)
5.	At the top of the Chrome window type "localhost:8000" in the web address bar (do not type the quotes)

You should now see the software in the Chrome browser window.

Vagrant

For a clean testing environment use Vagrant. For details on "public_network" see VagrantDocs.

  1. Open a terminal
$ mkdir LaserWeb
$ cd LaserWeb
$ vagrant init
$ vagrant box add ubuntu/trusty64
  1. Edit: Vagrantfile
config.vm.box = "hashicorp/precise32"
config.vm.network "public_network"
  1. In the terminal
$ vagrant up
$ vagrant ssh
$ sudo apt-get install nodejs nodejs-legacy npm build-essential git
$ git clone https://github.com/openhardwarecoza/LaserWeb.git
$ cd LaserWeb
$ npm install
  1. Find public IP

$ ifconfig eth1 is your "public_address"

  1. Start LaserWeb! (Use public_address:8000 on your local machine)

$ nodejs server.js

Docker

Another way to setup a clean test environment but with out building a full VM.

Build a Docker image with:

mkdir LaserWeb
wget https://raw.githubusercontent.com/openhardwarecoza/LaserWeb/master/Dockerfile
docker build -t laserweb .

Then run it either in the foreground like this:

docker run -p 8000:8000 --rm -it --name laserweb laserweb

Or in the background like this:

docker run -p 8000:8000 -d --name laserweb laserweb

Connect to port 8000 on your local machine.

You can shut it down like this:

docker stop laserweb

Raspberry Pi 2 (Jessie)

Procedure courtery of @LordFennec : LaserWeb#3

  1. Open a terminal
  2. Enter the following command sudo apt-get install build-essential python g++ make
  3. Install node.js for the Raspberry Pi using this script: https://github.com/midnightcodr/rpi_node_install

  7. Finally enter nodejs server.js

Mac OS X

Procedure courtery of @quillford : LaserWeb#10

  1. Download and install nodejs version node-v0.12.7 (NOTE: At the time of writing SerialPort is not supported on Node,js 4.0+) from https://nodejs.org/download/release/v0.12.7/ Note2: Compiling SerialPort sometimes fails. Read the auhors blog post about why its hard to manage over at http://www.voodootikigod.com/on-maintaining-a-native-node-module/
  2. cd to a directory to put LaserWeb in
  3. Open a terminal and enter git clone https://github.com/openhardwarecoza/LaserWeb.git
  4. Enter cd LaserWeb in the terminal window
  5. Enter npm install
  6. Now you can start it with node server.js

Config

edit config.js to change serial baud rate and web port edit /i/gcode-viewer/ui.js to change size of your laser's bed

Running

// standalone

node server.js

// with forever

npm install -g forever
forever start server.js

Access Instructions

After a successful start, the terminal / command promt should display something like this:

Successful start

Once you see that, open a web Browser and go to the URL as shown in the terminal (usually 127.0.0.1:8000, or the IP address of the device running Laserweb for example http://192.168.0.150:8000 - you can also access this IP from any device on the network)

The default port 8000, you can change it by editing config.js.

Access: http://hostaddress:8000/

Timelapse

There is a bash script names rrw_timelapse.sh in this repository which you can run on a Linux or BSD machine to generate a timelapse from the built in RRW Webcam server.
