# Ensuring Smooth Vertical Travel

## Vertical Travel

Optii Odometry should smoothly travel vertically without catching. When the wheel is pressed upwards, the only resistance that should be felt is that of the compression springs. 

If the odometry pod does not always spring back quickly into place when released, this may cause odometry readings to be inaccurate.

If your team experiences this issue, it can be resolved with the following methods.

## Loosening Carriage Bolts

The 2 M4 countersunk bolts shown below may be too tight which can cause inconsistencies with the linear motion of Optii Odometry. Simply use a 2.5 mm allen key to slightly loosen each bolt (approximately one half turn).

{% hint style="warning" %}
Please ensure that the bolt remains in contact with the nyloc of the M4 nut (the blue ring). If not in contact, this bolt can loosen with vibrations.
{% endhint %}

## Positioning Shoulder Bolts

It is important to ensure that the 2 M5 shoulder bolts are seated within the mounting plate correctly. If the bolt is not completely within the counterbore, press it into place. If it is too difficult to press into place, it may be helpful to use a 3 mm allen key to turn the bolt while pressing down.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.optii.com.au/odometry-v1/user-guide/ensuring-smooth-vertical-travel.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
