The app we use to pass GCODE to our RepRap 3D printer.

#Node.js 3D Printer App #####This is the Node.js app we use at Redweb to print out objects described in GCODE.

###Usage The app is pretty simple, just execute it and leave it running until completion. There is no point in the applications execution that will require user intervention.

In order to start the program you need to pass both the serial port you will be connecting to your printer on and the path (either relative or absolute) to the GCODE for the thing your printing.

node print.js --port "/dev/tty-blah-blah" --file "printFiles/helloWorld.gcode"

The app should work for any device that uses a serial port for communication and is expecting GCODE. Here at Redweb, We have a MKII RepRap Mendel variant.

###Initial Setup This app uses a few modules, Voodootikigod's Serialport library for communicating with the printer and "Substack's optimist" for argument parsing.

npm install

in the directory with the package.json file will install the modules needed for the app, then you're ready to go.

###Possible Arguments

Manadatory

• --file "PATH/TO/PRINTFILE"
• --port "SERIAL PORT FOR PRINTER CONNECTION. USUALLY /dev/tty.something"
• --baudrate 19200 etc. - The baudrate for the serial port connection

Optional

• --speed 1.0 - This is a multiplier that will modify the travel rate of the printhead. This is something we need for our printer.
