A Tessel 2 server for controlling a ShapeOko/XCarve from a remote machine using Easel.
Please see the Tessel 2 Start Page to provision your Tessel 2 before continuing.
Plug your Arduino (with GRBL flashed to it), to the Tessel 2 using a USB cable. The Arduino presents itself as a serial
device at /dev/ttyACM0. This is hard-coded in lib/serial_port_controller.js if you need to chage it to a different value.
The Tessel needs to have the hostname set to xcarve.local, so rename it using the CLI tools:
$ t2 rename xcarve
Download or clone this repo into a directory. Then cd into this directory and run:
$ npm install
There is a bug with the serialport package when it tries to enumerate the available serial devices on
the Tessel 2; so for now you need to manually list them in the config file: config.json. This file should have
been created for you in the previous step; if not, just copy the example-config.json file and edit as needed.
The device in the example file is from an Arduino UNO connected via USB to the Tessel 2. You might have to
access the Tessel using t2 root and run ls /dev/tty* to find the correct device.
This only needs to be done once and then everytime you power on the Tessel, it will start up the server and listen for connections from Easel.
$ t2 push iris.js
Alternatively, if you want to see the console output while it is running, you can do this:
$ t2 run iris.js
In order for Easel to find and communicate with the Tessel, you need to install the proxy server on the computer on which you are using Easel. Please follow the instructions here: https://github.com/adafruit/xcarve-proxy. This proxy will foward websocket traffic from the browser to the Tessel.
Some of the code included was extracted from v0.2.7 of the Easel local OS X installer.
