Bambulab API

🚧 WORK IN PROGRESS 🚧

This crate is still in development and not ready for production use. Breaking changes may occur at any time.

bambulab is a async Rust crate that provides a channel based client for interacting with Bambu Lab devices over their MQTT broker.

Features

• Subscribe to printer messages like print progress, temperatures, errors, etc.
• Publish commands to the printer
• Support for P1P, P1S and X1C printer

Usage

First, add bambulab to your dependencies:

cargo add bambulab

Then, use the Client struct to create a new client and connect to a printer:

use bambulab::{client::Client, command::Command};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let host = "printer-ip-or-hostname";
    let access_code = "printer-access-code";
    let serial = "printer-serial-number";

    let (tx, mut rx) = tokio::sync::broadcast::channel::<Message>(25);

    let mut client = Client::new(host, access_code, serial, tx);
    let mut client_clone = client.clone();

    tokio::try_join!(
        tokio::spawn(async move {
            client.run().await.unwrap();
        }),
        tokio::spawn(async move {
            loop {
                let message = rx.recv().await.unwrap();
                println!("received: {message:?}");

                if message == Message::Connected {
                    client_clone.publish(Command::PushAll).await.unwrap();
                }
            }
        }),
    )?;

    Ok(())
}

Please note that you need to call subscribe() to allow the API to listen to messages.
