What it does

Shows a tiny menu‑bar/tray icon that gives you live status, camera feed and automation controls for every 3D printer in your fleet.

When to use it
  • •You run several Bambu Lab, Prusa or Klipper‑based printers and need a single glance at health, temperature and print progress.
  • •You want to trigger simple automations (e.g., pause all printers when a fire alarm goes off) without writing custom scripts.
  • •You prefer a local‑only solution that never sends your printer data to the cloud.
Ready-to-paste prompt
`./.build/release/gantrybar --config ~/.gantrybar.yaml --trigger "printer.temperature > 260" --action "printer.cooldown"` – this runs a one‑off command that will automatically send a cooldown signal to any printer whose hotend exceeds 260 °C.
Heads up: Gantrybar authenticates to each printer via its own API key; if the key is missing or wrong the printer will appear offline. Make sure you generate API keys in each printer’s web UI and store them securely in the YAML config before starting the app.
