meltingplot.duet-simplyprint-connector 1.3.11rc1

Simplyprint.io connector for 3D printers running Duet firmware.

This package acts as a bridge between Duet-based 3D printers and the SimplyPrint.io cloud service.

It communicates with the printer using the Duet HTTP API. For more information, visit https://github.com/Duet3D/RepRapFirmware/wiki/HTTP-requests.

Communication with SimplyPrint.io is handled via the simplyprint-ws-client.

Camera support uses the simplyprint-ws-client camera system with an HttpCameraProtocol that handles both single JPEG snapshot endpoints and multipart MJPEG streams.

Note

SimplyPrint maintains an upstream version of this connector at https://github.com/SimplyPrint/integration-duet3d.
