Live temperature readings update every few seconds:

Print Progress¶

When a print is active, you'll see:

• Progress bar - Visual completion percentage
• Current layer - Layer X of Y
• Time remaining - Estimated time to completion
• Filament used - Grams consumed so far

HMS Error Monitoring¶

The Health Management System (HMS) monitors printer health and displays issues in real-time.

Status Indicator¶

The HMS indicator is always visible on printer cards:

Error Details¶

Click the HMS indicator to see:

• Error code and description
• Affected component
• Recommended action
• Link to Bambu Lab support article

WiFi Signal Strength¶

The printer card displays WiFi signal strength:

Weak signal can cause connection drops and print monitoring issues.

Total Print Hours¶

Track cumulative print time for each printer:

• Displayed on the printer card
• Useful for maintenance scheduling
• Helps identify heavily-used machines

MQTT Debug Logging¶

Built-in debugging tool for printer communication:

Starting Debug Logging¶

1. Click the settings icon on a printer card
2. Click Start MQTT Debug
3. Messages are captured in real-time

Viewing Messages¶

Features:

• JSON payloads - Expandable for detailed inspection
• Filter by type - Focus on specific message types
• Search - Find specific content
• Auto-refresh - New messages appear automatically

Use Cases¶

• Troubleshooting connection issues
• Understanding printer behavior
• Debugging automation problems
• Reporting issues to developers

WebSocket Architecture¶

Bambuddy uses WebSocket for real-time updates:

graph LR
    A[Printer] -->|MQTT| B[Bambuddy Backend]
    B -->|WebSocket| C[Browser]
    B -->|WebSocket| D[Browser 2]
    B -->|WebSocket| E[Mobile]

How It Works¶

1. Printer sends status updates via MQTT over TLS
2. Backend processes and stores the data
3. WebSocket broadcasts updates to all connected clients
4. Browser updates the UI instantly

Connection Features¶

Performance¶

• Latency: < 1 second typical
• Bandwidth: Minimal (delta updates only)
• Scalability: Multiple clients supported

Printer Images¶

Customize your printer cards with images:

1. Click the settings icon on a printer card
2. Upload a printer image
3. The image displays on the card
