OctoPrintPlugin

Cura plugin which enables printing directly to OctoPrint and monitoring the progress

This plugin started out as a fork of the UM3NetworkPrinting plugin: https://github.com/Ultimaker/UM3NetworkPrintingPlugin

Installation

Manually:
- Make sure your Cura version is 2.2 or newer
- Download or clone the repository into [Cura installation folder]/plugins/OctoPrintPlugin or in the plugins folder inside the configuration folder. The configuration folder can be found via Help -> Show Configuration Folder inside Cura. NB: The folder of the plugin itself must be OctoPrintPlugin
- If you are running Cura from source, make sure you install python-zeroconf using pip: pip3 install python3-zeroconf. Released versions of Cura already meet this requirement.
Cura PPA (*Ubuntu):
- Add the cura PPA via (if not already done): sudo add-apt-repository ppa:thopiekar/cura
- Update APT via: sudo apt update
- Install the plugin via: sudo apt install cura-extra-plugin-octoprint

How to use

Make sure OctoPrint is up and running, and the discovery plugin is not disabled
In Cura, add a Printer matching the 3d printer you have connected to OctoPrint
Select "Connect to OctoPrint" on the Manage Printers page.
Select your OctoPrint instance from the list and enter the API key which is available in the OctoPrint settings.
From this point on, the print monitor should be functional and you should be able to switch to "Print to Octoprint" on the bottom of the sidebar.

Notes on UltiGCode (Ultimaker 2/Ultimaker 2+)

The Ultimaker 2(+) family uses a flavor of GCode named UltiGCode. Unfortunately printing using UltiGCode flavor does not work when printing over the USB connection. That is why using OctoPrint does not work with UltiGCode flavor.

For the Ultimaker 2/Ultimaker 2 Extended, you can use "Machine Settings" on the "Printers" pane of the preferences to change your GCode flavor to "RepRap (Marlin/Sprinter)".

The Ultimaker 2+/Ultimaker 2 Extended+ currently don't support "Machine Settings". You can use one of these alternative printer definitions instead:

Ultimaker2+: https://gist.github.com/fieldOfView/bf536254add126fd4c7b36bc347fce73
Ultimaker2 Extended+: https://gist.github.com/fieldOfView/a52caf946d0a0df522c22298a6c94209

Copy these files into the resources/definitions folder of your Cura application. Restart Cura and add a new printer. You should see the option to add a Ultimaker 2+ (RepRap) and/or Ultimaker 2 Extended+ (RepRap) (depending on which file(s) you installed.
