## 🧪 Testing the Features

### Test Cost Calculator
```bash
# Select 3 models in the UI
# Click cost calculator (if added to UI)
# Or call: fetch('/api/models/batch/cost', {...})
# Expected: JSON with cost estimates
```

### Test Full-Text Search
```bash
# Search for "bambu" in search bar
# Should find models mentioning Bambu in any field
# Filter by license "MIT"
# Should only show MIT licensed models
```

### Test Bambu Integration
```bash
# Get access token from Bambu Labs account
# Add printer via UI modal
# Click "Refresh" to check connection
# Expected: Printer connected status
```

### Test Theme Toggle
```bash
# Click moon icon in navbar
# Should switch to dark theme
# Refresh page
# Theme should persist
# Click sun icon to switch back
```

## 📊 Database Migrations Applied

### Users Table
```sql
ALTER TABLE users ADD COLUMN theme TEXT DEFAULT 'light';
```

### Models Table
```sql
ALTER TABLE models ADD COLUMN license TEXT DEFAULT 'Unknown';
```

### New Table
```sql
CREATE TABLE printer_settings (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  user_id INTEGER,
  printer_type TEXT,
  printer_name TEXT,
  access_token TEXT,
  serial_number TEXT,
  model_name TEXT,
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
);
```

These migrations run automatically on first server start via `database.js`.

## 🐛 Troubleshooting

| Issue | Solution |
|-------|----------|
| Cost calculator shows "Unknown Confidence" | Normal - file-based estimate. Consider extracting 3D dimensions for accuracy |
| Bambu connection fails | Verify access token, serial number, and internet connection |
| Theme not persisting | Ensure you're logged in and backend is reachable |
| Search not finding results | Try broader terms, check all filters are cleared |
| License not showing | Ensure license was set when uploading model |
