Important Notes

• WebSocket support is required — The Upgrade and Connection headers are essential for real-time printer status updates and camera streaming.
• Increase client_max_body_size — 3MF files can be large. 500M is a safe value for print farms.
• Increase timeouts — Some operations (firmware updates, large uploads) take time.
