BambuSharp 1.0.0

BambuSharp

An open source .NET API for Bambu Lab printers.

Overview

BambuSharp is a comprehensive .NET library for communicating with Bambu Lab 3D printers over the local network. It provides real-time monitoring of printer status, temperatures, print progress, AMS (Automatic Material System) units, and much more through an easy-to-use API with full INotifyPropertyChanged support.

Features

• Real-time Printer Monitoring - Live updates via MQTT connection
• Comprehensive Status Information
  • Print progress, current file, layer information
  • Bed and nozzle temperatures
  • Extruder details with accurate temperature conversion
  • Nozzle specifications (diameter, type, wear percentage)
  • AMS units with filament information (type, color, remaining length)
  • IP camera settings and resolution
  • Light status (chamber light, work light, etc.)
  • Network interfaces and IP addresses
  • AI features (spaghetti detector, first layer inspector, etc.)
  • File upload status and progress
  • Cloud connectivity status
• Terminal UI - Cross-platform terminal-based monitoring interface with colored filament display
• INotifyPropertyChanged Support - Easy integration with MVVM applications
• Type-Safe API - Strongly-typed properties with units (using Meadow.Units for temperatures)

Installation

dotnet add package BambuSharp

Quick Start

Basic Connection and Monitoring

using BambuSharp;

// Create a printer instance with IP address and access code
var printer = new LocalPrinter("192.168.1.100", "your-access-code");

// Subscribe to property changes
printer.PropertyChanged += (sender, e) =>
{
    Console.WriteLine($"Property changed: {e.PropertyName}");
};

// Connect to the printer
await printer.Connect();

// Access printer status
Console.WriteLine($"State: {printer.State}");
Console.WriteLine($"Progress: {printer.PrintProgress}%");
Console.WriteLine($"Current File: {printer.CurrentFileName}");
Console.WriteLine($"Bed Temperature: {printer.BedTemperature.Celsius:F1}°C");
Console.WriteLine($"Nozzle Temperature: {printer.NozzleTemperature.Celsius:F1}°C");
Console.WriteLine($"Layer: {printer.CurrentLayer}/{printer.TotalLayers}");

// Access AMS information
foreach (var ams in printer.AmsUnits)
{
    Console.WriteLine($"AMS Unit {ams.Id}: {ams.Humidity}% humidity");
    foreach (var tray in ams.Trays)
    {
        Console.WriteLine($"  Tray {tray.Id}: {tray.FilamentType} - {tray.Color}");
        Console.WriteLine($"    Remaining: {tray.Remaining}mm of {tray.TotalLength}mm");
    }
}

// Disconnect when done
await printer.Disconnect();
printer.Dispose();

Available Properties

Core Status

• CurrentLayer / TotalLayers - Layer progress information
• RemainingMinutes - Estimated time remaining

Temperature Monitoring

• BedTemperature - Current heated bed temperature
• NozzleTemperature - Current nozzle temperature
• Extruder - Detailed extruder information including:
  • CurrentTemperature - Current nozzle temperature (device-level)
  • TargetTemperature - Target nozzle temperature
  • FilamentTemperature - Filament temperature
  • Status - Extruder status code

Hardware Information

Terminal UI

BambuSharp includes a cross-platform terminal-based monitoring interface built with Terminal.Gui:

• Real-time expandable tree view of all printer properties
• Colored filament display for AMS trays with high-contrast backgrounds
• Live updates without page refreshes
• Navigate with keyboard (arrow keys to expand/collapse)

Technical Details

MQTT Communication

BambuSharp communicates with Bambu Lab printers using MQTT over the local network:

• Real-time status updates (~1 second intervals)
• Automatic JSON deserialization with custom converters
• Reliable connection management

Requirements

• .NET 8.0 or later
• Network access to Bambu Lab printer
• Printer access code (found in printer settings)

Acknowledgments

• Built with Meadow.Units for type-safe unit handling
• Terminal UI powered by Terminal.Gui
• MQTT communication via MQTTnet
