# CANBUS to USB

## Currently Using CANBUS?

Looking at using Cartographer via USB instead of CANBUS? Follow the steps below to make the change!

***

## Step 1. Plug In Cartographer via CANBUS

## Step 2. SSH Into Your Host Device & Run The 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
```
