# CANBUS Flash

### CANBUS or USB

* If you ordered a USB flashed cartographer, you use the [USB Katapult Method](https://docs.cartographer3d.com/original-plugin/firmware-archive/firmware-updating/via-katapult/usb-flash)
* If you ordered a CAN flashed cartographer, you use the [CANBUS Katapult Me](https://docs.cartographer3d.com/original-plugin/firmware-archive/firmware-updating/via-katapult/canbus-flash)[thod](https://docs.cartographer3d.com/original-plugin/firmware-archive/firmware-updating/via-katapult/canbus-flash)

### Whats Required?

* Cartographer Probe
* Canbus to JST-PH Cable (For Katapult Canbus Flashing)

{% hint style="info" %}
Using the scripts below, you may need to use the **Install Prerequisites** option first to make sure everything is configured prior to flashing.
{% endhint %}

## CANBus Katapult Updating

## Step 1. Plug Cartographer in via CANBUS

## Step 2. Get Your UUID

This method requires prior knowledge of your **CANBUS UUID**.

This should have been supplied to you in your hardware box if purchased (insert date).

If you do not have your UUID. Visit [HERE](https://docs.cartographer3d.com/cartographer-probe/archive/classic-installation/klipper-setup#finding-the-serial-or-uuid) to get it.

## Step 2. SSH into Device & Run Script

```bash
cd ~
if [ -d ~/cartographer_firmware/ ]; then
    echo "Directory Exists - Starting Firmware Script"
    cd ~/cartographer_firmware/
    git pull
else
    git clone https://github.com/Cartographer3D/cartographer_firmware.git
fi
~/cartographer_firmware/scripts/firmware.py
```

## Step 3. Select Katapult - Can Menu

## Step 5. Find Latest Firmware

{% hint style="info" %}
Your CANBUS bitrare (if configured on your host device) should be detected and displayed. You should flash your cartographer with MATCHING bitrate firmware.
{% endhint %}
