My name is Arturo and I'm an iOS developer from Madrid, Spain
I have a project and this is: https://github.com/ArtCC/OctoPrint-Siri-RPi
With this project you will be able to control your 3D printer if you use OctoPrint as a print server with Siri from your iOS, iPadOS, macOS or HomePod using the Apple Shortcuts.
You will need a Raspberry Pi with OctoPrint and Node.js installed.
After following my tutorial you will be able to control by voice and Siri your 3D printer.
I hope you like the project, I'm open to all kind of help and modifications.
Thank you very much!
