Who am I?
Software engineer by day
Passionate code monkey by night
Proud owner of a 3D printer since late November 2012
Developer of OctoPrint since Christmas 2012 (that's
what holidays are for, right?)
Why Another Host
Software?
The Problem
PLA/ABS/yourFavoritePolymer fumes
Stepper motors can produce quite the racket
Takes up a lot of space in the office (printer, cable salad,
...)
Takes up the office computer (or the laptop)
The Solution
Just put the printer somewhere it doesn't disturb anyone,
like the shed, the basement or a spare bathroom.
But actually watching it print is so
mesmerizing and calming, and I also want
to make sure nothing goes wrong!
And Thus The Idea Of
OctoPrint Was Born!
What Was The Vision?
Run on a Wifi-enabled
Raspberry Pi
So I can just put it somewhere within my Wifi's range and
be able to access it without spending too much money on
this convenience.
Provide feedback regarding the
current printer state
(temperature, print job, etc)
So I can always be sure that it's doing what it's supposed
to be doing.
Include a webcam feed
So I can still watch the printer do its magic.
And Do All That In The
Browser!
So that I can quickly check up on it from any of my devices
without the need to install anything.
What's in the package?
Uploading and managing GCODE files on the
host or the SD card
Printing GCODE files stored on the host or the SD,
pausing and cancelling running print jobs
Monitoring the current progress, temperature and
printer communication and visualizing the object
being printed
Watching the print via the integrated webcam feed
and creating timelapse movies of the prints
Remote controlling the printer functions
Customizing the available controls
Getting notifications and triggering actions
based on certain events, like a print being done
Access control and user management so that
you can make your printer accessible over the internet
(also great for shared printers e.g. in hackerspaces)
All this in a responsive web interface using modern
web technologies that ensure an experience just
like on the desktop.
Demo time!
What's To Come?
Slicing STL files to GCODE (using Cura SteamEngine,
big kudos to +Ross Hendrickson)
An interface optimized for mobile devices
Plugin system for adding more specialized
functionality to the core application
Google Glass integration
(big kudos to +Adam Bryam)
... and much more
Patches welcome! :)

What you can do with events...
Automatically upload
timelapses to Youtube
events:
systemCommandTrigger:
- event: MovieDone
command: 'youtube-upload --email="<yourUser>"
--password="<yourPassword>"
--title="Timelapse: %(filename)s"
--description="Timelapse of %(filename)s, printed and recorded
via OctoPrint"
--category="Tech"
--keywords=OctoPrint "%(data)s"'
(Using youtube-upload)
Push notifications for Android
and iOS
- event: PrintDone
command: curl -s
-F "token=<yourApiToken>"
-F "user=<yourUserToken>"
-F "message=Completed %(filename)s"
-F "title=OctoPrint"
https://api.pushover.net/1/messages.json
(Using Pushover)
Send a notification to Pebble
- event: PrintDone
command: curl -s
-F "userId=<yourUserId>"
-F "userToken=<yourUserToken>"
-F "title=OctoPrint"
-F "body=Print of %(filename)s completed"
-F "type=notification"

(Using Pebble Connect with httpebble)
Under the hood
Written in Python (2.7) and loads of Javascript
Communication to the backend via AJAX and Sock.js
REST API is a work in progress
