Bambuddy — Self-Hosted Command Center for Bambu Lab 3D Printers

Introduction

Bambuddy is a self-hosted command center for Bambu Lab 3D printers. It communicates directly with printers over your local network using MQTT, eliminating the need for Bambu Lab's cloud services while providing real-time status, print history, and fleet management.

What Bambuddy Does

• Monitors real-time printer status including temperature, progress, and filament usage
• Manages print jobs across single or multiple Bambu Lab printers
• Tracks print history with statistics on filament consumption and print time
• Provides a responsive web dashboard accessible from any device
• Operates entirely on the local network without cloud connectivity

Architecture Overview

Bambuddy is a Python application using Flask for the web interface and Paho-MQTT to communicate with Bambu Lab printers over the local MQTT protocol. Printer state is polled and cached in a local SQLite database. The frontend is a responsive web dashboard that displays real-time telemetry. The entire stack runs in a single Docker container.

Self-Hosting & Configuration

• Deploy via Docker with printer IP and access code as environment variables
• Find your printer's access code in the Bambu Lab app under device settings
• Add multiple printers by providing comma-separated IPs and access codes
• Mount a persistent volume for /app/data to retain print history
• Run on the same network as your printers; no internet access required

Key Features

• Cloud-free operation preserves privacy and works during internet outages
• Multi-printer dashboard for managing print farms from a single view
• Real-time temperature graphs for hotend, bed, and chamber
• Print history with per-job filament usage and duration tracking
• Mobile-friendly responsive design for checking prints on the go
