🧪 Testing the Features

Test Cost Calculator

# 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

# 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

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

Test Theme Toggle

# 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

ALTER TABLE users ADD COLUMN theme TEXT DEFAULT 'light';

Models Table

ALTER TABLE models ADD COLUMN license TEXT DEFAULT 'Unknown';

New Table

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
