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 HostSoftware?

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 somesmerizing and calming, and I also want

to make sure nothing goes wrong!

And Thus The Idea OfOctoPrint Was Born!

What Was The Vision?

Run on a Wifi-enabledRaspberry 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 thecurrent 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 TheBrowser!

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 actionsbased 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 modernweb 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 )

An interface optimized for mobile devicesPlugin system for adding more specialized

functionality to the core application

+Ross Hendrickson

(big kudos to )

Google Glass integration

+Adam Bryam

... and much more

Patches welcome! :)

Want to try it?

With OctoPi there's a dedicated distribution forthe Raspberry Pi, created by :+Guy Sheffer

What you can do with events...

Automatically uploadtimelapses 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 Androidand 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" https://ofkorth.net/pebble/send

(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
