{% endstep %}

{% step %}

### Install the new XYZ PCB

Insert the new XYZ PCB and tighten down the 8 T10 Torx bit to secure it in place.

{% hint style="info" %}
Make sure that the ribbon cable is on top of the board when you install it.
{% endhint %}

Open the new connector and insert the ribbon cable. Ensure that the ribbon cable is fully inserted into the connector before closing the locking tab.

{% hint style="warning" %}
Remember to be very gentle with the ribbon cable and connector when re-inserting. The blue tape should be level with the connector and you shouldn’t feel any resistance when the cable goes in. Once in, close the locking tab on the top of the connector.
{% endhint %}

Once the ribbon cable is secure remount the cable clamp using a T10 torx bit to tighten down the 2 screws.

{% hint style="warning" %}
&#x20;Do not over tighten!&#x20;
{% endhint %}

{% step %}

### Re-install the calibration plate cover

Re-install the black calibration area cover using a T20 torx bit and replace the calibration plate and XYZ positioner thumbscrew. The XYZ positioner thumbscrew should be finger tight.
