OctoRest

Python client library for OctoPrint REST API

This is continued work after the great start by Miro Hrončok of covering the OctoPrint REST API. Nearly all current functionality in the API has been covered (up to OctoPrint 1.3.11), but as of yet I have not had time to add extensive testing for all aspects of the API.

Installation

The easiest way to install the package is via pip:

$ pip install octorest

Examples

You may want a function which returns an instance of the OctoRest object connected to your printer.

def make_client(url, apikey):
     """Creates and returns an instance of the OctoRest client.

     Args:
         url - the url to the OctoPrint server
         apikey - the apikey from the OctoPrint server found in settings
     """
     try:
         client = OctoRest(url=url, apikey=apikey)
         return client
     except ConnectionError as ex:
         # Handle exception as you wish
         print(ex)

Once we have a client we can do many a cool thing with it! For example the following retrieves all the G-code file names on your OctoPrint server and adds them to a string which is printed out.

def file_names(client):
     """Retrieves the G-code file names from the
     OctoPrint server and returns a string message listing the
     file names.

     Args:
         client - the OctoRest client
     """
     message = "The GCODE files currently on the printer are:\n\n"
     for k in client.files()['files']:
         message += k['name'] + "\n"
     print(message)

Maybe you want to stop your print and then subsequently home the printer. This is very simple to do using OctoRest!

def toggle_home(client):
     """Toggles the current print (if printing it pauses and
     if paused it starts printing) and then homes all of
     the printers axes.

     Args:
         client - the OctoRest client
     """
     print("toggling the print!")
     client.toggle()
     print("Homing your 3d printer...")
     client.home()
