# Initial Startup
### ※Check Wiring
Before powering on, perform a final check of all connections:
* 110/220V wiring section
* 5V/24V wiring section
* Ensure all jumpers are inserted in the correct positions
* Verify all drivers are inserted into the appropriate driver slots and properly seated
### ※**Connect WiFi Using SSH Software**
Once the mainboard is wired, you’ll need to connect and configure its WiFi settings. Before proceeding, ensure you have downloaded the PuTTY software.
* **Windows**:\
PuTTY is a widely-used SSH client. You can download it \[[here](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)].
* **macOS/Linux**:\
These systems come with a pre-installed SSH client. Simply use the `ssh` command in the terminal.
1. Use the included USB Type-C data cable to connect the Gemini motherboard’s upper communication port to your computer's USB port.
2. On your computer, open the Device Manager and identify the port labeled "CH340."
3. Launch PuTTY, select **\[Serial]** as the connection type, set the baud rate to **\[115200]**, and enter the **\[COM12]** port displayed for CH340. Please note, the COM port may vary depending on your system—enter the one shown on your device.
3. After a short wait, the terminal screen should appear. If the screen remains blank, try pressing the **Space** or **Enter** key. If the issue persists, disconnect and reconnect the device.
5. After a brief wait, the screen should resemble the image above, indicating a successful login.
6. Type **`nmtui`** and press **Enter** to access the configuration page. Use the arrow keys to navigate and select the second option, then press **Enter**.
7. Use the arrow keys to select **WiFi**, then enter the password and press **Enter** to exit. Once connected, a **`*`** will appear in front of the WiFi name. Press **ESC** to exit the menu.\
If no WiFi information appears, check if the WiFi module is properly inserted or if it's in the correct location.
8. Enter the command **`ip a | grep inet`** and press **Enter**. The returned message will display the network IP of the motherboard, highlighted in the red box. Be sure to record this IP, as it will be needed to access the console from either a phone or computer in the future.

**Do Not Exit the SSH Software**
Please do not exit the SSH software; we will proceed to the next step immediately.
{% endhint %}
### ※Flash Firmware to the Display Screen
1. In the terminal, enter the following commands:
```
cd ~/klipper/
make -j4 flash FLASH_DEVICE=0483:df11
```
2. After running the above command, the system may prompt you to enter a password. Enter the password: mellow.
3. Wait for the firmware to be flashed.
4. After the flashing is complete, restart the system with the following command:
```
sudo reboot
```
5. Once the system restarts, the display screen should light up.
{% hint style="info" %}
We will perform further debugging and printing directly in the web console, so you can close the SSH software now. (The SSH software will only be used for specific operations when needed.)
{% endhint %}
**Do I need to use a data cable for every SSH connection?**
No, once you obtain the device's IP address, you can connect directly using Putty or another SSH client via the IP address.
When logging into VORON 0.2, after entering the device's IP, you'll be prompted to input the username and password:
* **Username**: fly
* **Password**: mellow
**Note**: Make sure to use lowercase letters for both the username and password. The password won’t be displayed as you type, so after entering it, just press Enter to confirm.
Once logged in, you're ready to proceed with further actions.
### ※**Login to the Console**
Open a web browser on your computer or mobile device and enter the IP address obtained in the previous step. This will take you to the Fluidd web console.\
Ensure that your computer or mobile device is connected to the same network as your printer.\
For best performance, it’s recommended to use browsers like **Microsoft Edge**, **Google Chrome**, or **Firefox**. Avoid using **QQ Browser** or **360 Browser** as they may cause issues.
{% hint style="info" %}
**Why is the webpage interface stuck on loading and I can't log in?**
1. Make sure that both your computer and the VORON 0.2 are connected to the same local network (LAN).
2. Check if the VORON 0.2 device is too far from the router, which could cause connection issues.
3. Also, note that the VORON 0.2 only supports 2.4G Wi-Fi. You may need to configure your router accordingly to ensure compatibility.

Once the console has started successfully, you can unplug the USB data cable and connect the power cord to provide 24V power to the printer.
