After you have captured a wand wave (see [Perform a wand wave](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397968969)), you set the volume origin and axes so the cameras and volume in Evoke reflect the actual positions of the cameras in relation to the volume, as well as to each other.

1. To enable you to see the axes in relation to the volume, in the **Workspace**, change the view to ** 3D View**.
2. Place the calibration device on the volume floor in the position you want the volume origin to be and in the orientation you want the axes to be (reflected in the axes displayed in the **3D View**).
  - Z axis: blue line
  - X axis: red line
  - Y axis: green line
3. In the **Camera Calibration** panel, go to the **Volume Setup** section, ensure advanced parameters > Macro (inline-media-image)

 is selected and in the list below **Set Volume Origin**, ensure the appropriate Active Wand is selected (normally one of the Active Wand options).
  :check_mark: **Tip**: Using a Vicon Active Wand enables you to set up your volume coordinate system quickly and easily. However, using a larger calibration object (for example, markers embedded in the volume floor and wall) can improve calibration stability and consistency over time, particularly in larger volumes. For more information, see [Create a custom calibration object](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397968685/Create+basic+objects#CustomCalObject).
4. In the **Volume Setup** section, click **Start Set Origin**.
  The button displays** Set Origin ** and is unavailable until Evoke has enough data to set the origin.
  If you need more information about why the button is unavailable, hover the mouse pointer over the button to view its tooltip. For more information, see [About collecting frames](#AboutCollectingFrames).
5. Click ** Set Origin**.
6. In the **3D View**, ensure that in the **View Filters** options, **Cameras** is selected.
  In the **3D View**, **Perspective** view, all of the cameras shift as a group, so the origin of the volume is aligned with the wand.

About collecting frames

If Evoke detects an issue with setting the origin, the tooltip for the **Set Origin** button displays the following information in the format 'Collecting frames (*reason origin can't be set*)' so that you can take the appropriate action:

> Macro (scroll-tablelayout)

| Tooltip text (reason) | Action |
| --- | --- |
| L-Frame motion detected | Ensure the calibration object remains motionless while you are setting the origin. |
| No labeled data | Nothing is being tracked in the volume. Ensure the wand is switched on and is in Continuous mode. |
| L-Frame not tracked | The chosen calibration object was not detected. Ensure the wand is switched on and in Continuous mode. |
| Multiple objects detected | Remove any extra objects that are being tracked in the volume. |
| Insufficient frames | The calibration object hasn't been tracked in enough frames yet. Check that the L-frame is being tracked consistently. |

After you have set the volume origin, set the floor plane using the Pulsars in the volume. For more information, see [Set the floor plane](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397969050).
