+## Test the gantry
+
+Once your gantry is configured and connected, go to the [**Control** tab](/manage/fleet/robots/#control) and click on the gantry's drop-down panel.
+
+Use the panel to adjust the position of the actuator on the axis and check whether it moves as expected.

+If the gantry does not appear on the **Control** tab, or if you notice unexpected behavior, check your robot's [**Logs** tab](/manage/fleet/robots/#logs) for errors, and review the configuration.
