Nautilus for OctoPrint provides a customised user interface, that has been optimised for iOS devices.
The application will manage the printer configuration (URL and API key) and load the Nautilus plugin web application which provides all the rest of the functions.
By default, the application allows one printer to be configured, but support for multiple printers can be added ^via In-App purchase. Multi-printer configuration is supported only on devices with iCloud enabled.
The OctoPrint Nautilus plugin needs to be installed on every configured printer. Install the Nautilus plugin (available for OctoPrint version 1.3.0 and above) via the OctoPrint plugin manager.
The application will receive notifications from OctoPrint on selected events.
This is NOT an official mobile version of OctoPrint.
