### Gather Your Tools

You will need your smart touch probe, a new stylus tip, and a 1mm-diameter stiff wire or hex key. For the wire, we’re using Malin Co 0.040” Hard S.S. X-Brite wire, trimmed to about a 1.5” length.

{% endstep %}

{% step %}

#### Loosen the current stylus tip

Insert the 1mm diameter wire (or hex key) through the slot near the top of the stylus. With the smart probe lying on a table with the mounting side down, use the wire to twist the probe tip to the left to loosen it (the probe tip uses a standard thread). When loose, use fingers to twist out and remove the probe tip.

{% endstep %}

{% step %}

#### Insert the new tip

Gently thread the new probe tip into the smart probe and get it finger tight. Next, insert the wire through the slot near the top of the new tip, and torque the probe towards the right to gently tighten the probe tip.

#### Burn in the new probe tip

It is important to burn in the new probe tip to ensure you get accurate measurements for the life of the new probe tip. This process will take about 5 minutes.

First, mount the smart probe with the new tip on the NOVA platform using either module port. Next, open the hardware attachments settings by clicking its icon in the bottom left corner:

Click on the **Touch Probe** that is shown attached to the machine:

Then run the **Burn In** for the probe:

{% hint style="warning" %}
Don't navigate anywhere else in the software while the burn in is running, this could cause it to be interrupted and error out.
{% endhint %}

When the burn in is complete, your probe is ready to go!
