EZUI has five main screens. The main screen is the one you see first when you connect. The others — Favorites, Tools, Settings, and Calibration — are accessed from buttons on the main screen.
Main Screen Layout
The main screen has two primary areas: the filter panel at the top and the drill list below it. Filtering and drill loading from this screen are covered in Selecting Drills.

Below the drill list, five buttons provide access to the rest of the interface:
| Button | Icon | Purpose |
|---|---|---|
| Add Favorite | Heart with + | Adds the currently displayed drill to your Favorites list |
| Tools | Tools/wrench | Opens the Tools screen for the current drill |
| Favorites | Heart | Opens the Favorites screen |
| Settings | Gear | Opens Settings for configuration, updates, and calibration |
| Help | Question mark | Links to this documentation |
Navigating Between Screens
Each secondary screen (Favorites, Tools, Settings, Calibration) has a Back button — a left-facing arrow icon — that returns you to the main screen.
