## Save your calibration presets

Some of our machine calibration presets are stored onboard the control board. If we replace the control board we will need to manually write the calibration presets to the new control board.&#x20;

### Log into NOVA

{% endstep %}

{% step %}

### Open the command console

Enter the `~` or `` ` `` character to open the console.&#x20;

<figure><img src="/files/xU61tSaxBjTBYKsWqNKk" alt=""><figcaption></figcaption></figure>
{% endstep %}

{% step %}

### Capture the calibration values

Type the command `M520` into the console to output the current calibration values. Take a screenshot of the command line output like this to save for later:&#x20;

{% endstepper %}

## Replace the control board

{% stepper %}
{% step %}

### Disconnect NOVA from power

Ensure that NOVA is turned off with the power button and then unplug the power cable.

{% endstep %}

{% step %}

### Remove the backplate

With a T20 Torx bit remove the 6 screws (2 on the back side, 4 on the bottom of the panel) securing the back panel. Once the screws are out you can pull the back panel out by tilting it up slightly and then pulling away from the machine.

{% endstep %}

{% step %}

### Remove the control board

Carefully detach all of the cables from the main control board.&#x20;

{% hint style="info" %}
In case you've forgotten, here is a video of how to properly disconnect a ribbon cable:

{% endhint %}

<figure><img src="/files/DoJn1Sl901xUuk5ocSGW" alt=""><figcaption></figcaption></figure>

Unscrew the 4 screws holding the control board in place with a T10 torx and remove the board.

<figure><img src="/files/tzEbJUD3bP8LpZlnRFFj" alt=""><figcaption></figcaption></figure>
{% endstep %}

{% step %}

### Swap the compute module (Optional)

If the new control board you received does not have a compute module mounted to it we will need to swap it from the current control board.&#x20;

{% hint style="success" %}
If your new control board has a compute module installed you can skip this step!
{% endhint %}

With the control board off, you can remove the two screws holding the compute module in place, with a T6 Torx.

<figure><img src="/files/jkqeu3ZcIRCjxsiB12D1" alt="" width="563"><figcaption></figcaption></figure>

Release the two locking tabs on the module and it will swing up towards you about 10°. It can now be removed by sliding it down and out.

<figure><img src="/files/x89wmDXwo5mcatltffv5" alt=""><figcaption></figcaption></figure>

<figure><img src="/files/hTA0xyi3uUHrjQh64At0" alt=""><figcaption></figcaption></figure>

Install the compute module onto the new control board by reversing the previous steps. Slide the compute module into the slot on the control board at a 10° angle and push down to engage the two locking tabs.

<figure><img src="/files/3RqxdiEQlSeF87lmTrUY" alt=""><figcaption></figcaption></figure>

Secure the compute module in place with the two screws and a T6 Torx.
{% endstep %}

{% step %}

### Install the new control board

Mount the new control board onto NOVA with the four screws using a T10 Torx.

<figure><img src="/files/tzEbJUD3bP8LpZlnRFFj" alt=""><figcaption></figcaption></figure>

Plug in the cables for the power button, leds, motors, vacuum board, ribbon cables and port board. Again being gentle with the ribbon cables when plugging them back in.&#x20;

{% hint style="info" %}
The blue tape should be level with the connector. You shouldn’t feel any resistance when they go in. Once in, close the black locking tab.
{% endhint %}

{% step %}

### Reattach the backplate <a href="#reattach-the-backplate" id="reattach-the-backplate"></a>

Put the back plate back into place and with a T20 Torx bit secure the 6 screws (2 on the back side, 4 on the bottom of the panel).

{% endstep %}

{% step %}

### Turn NOVA back on! <a href="#turn-nova-back-on" id="turn-nova-back-on"></a>

You can now plug NOVA back in and turn it on using the power button.
{% endstep %}
{% endstepper %}

## Set your calibration presets

{% stepper %}
{% step %}

### Log into NOVA

<figure><img src="/files/Vg0j5UnqMweQANaWPmjm" alt=""><figcaption></figcaption></figure>
{% endstep %}

{% step %}

### Open the command console

Enter the `~` or `` ` `` character to open the console.&#x20;

<figure><img src="/files/xU61tSaxBjTBYKsWqNKk" alt=""><figcaption></figcaption></figure>
{% endstep %}

{% step %}

### Save the calibration values

Type the command `M520` into the console to output the current calibration values. Take a screenshot of the command line output and send it to our support team by email (<support@voltera.io>) or chat along with the screenshot of your previous calibration values. &#x20;

<figure><img src="/files/Y4WdhBsZjgGoBXYO0zL3" alt=""><figcaption></figcaption></figure>

Our support team will now give you a list of commands to copy and paste into the console that will save your previous calibration values to the new control board. &#x20;
{% endstep %}
{% endstepper %}

## Repair Complete!

Congratulations, you have successfully replaced NOVAs control board!

Please reach back out to our support team through email (<support@voltera.io>) or the chat to let them know everything went well. We will arrange a shipping label to return the old parts back to us for further testing.
