How do I install the Wi-Fi module on my CREALITY Ender 3 3D printer?

[SanAurora]

To install and configure the Wi-Fi module on your CREALITY Ender 3 3D printer, follow these steps:

1. Preparation: Ensure your Ender 3 is powered off before you begin.
2. Wiring and Connection: The Wi-Fi module wires need to be connected in the correct sequence. Typical wire colors and their functions are:
   • Red: 5-12 VDC
   • Blue: GND
   • White: TX -> RX
   • Black: RX -> TX
3. Module Insertion: Plug the Wi-Fi module's connector into the TFT socket located on your printer's motherboard.
4. Power On: Connect the power supply and turn on your CREALITY Ender 3.
5. IP Address Display: After the printer boots up, the LCD screen will display an IP address, such as 192.168.0.1.
6. Network Access: On your computer or mobile device, open your Wi-Fi settings.
7. Network Selection: Find and select the network named "3D Printer" from the available networks.
8. Password Entry: Enter the password: 12345678.
9. Configuration Page Access: You should be automatically redirected to a configuration page. If not, open a web browser and enter the IP address displayed on your printer's screen (e.g., 192.168.0.1) in the address bar and press Enter.
10. Language and Firmware Selection: Choose your preferred language and then select the type of firmware installed on your Ender 3. If you're using the original factory firmware, select "Repetier". If you've updated the firmware, select the appropriate option (often Marlin).
11. Baud Rate Setting: Set the baud rate to match the setting used when connecting via USB, which is usually 115200.
12. ESP Name: Give your Wi-Fi module a custom name, such as "Ender", and click "NEXT".
13. Operating Mode Selection: You have two operating modes:
    • AP Mode: Creates its own Wi-Fi network. In this mode, the printer won't be visible on your home network, and you'll need to connect to the "3D Printer" network and set a new password.
    • STA Mode: Allows you to connect your printer to your home Wi-Fi network. Select your home network by clicking the magnifying glass icon, enter your Wi-Fi password, and click "Set".
14. Restart the Printer: Once configured, restart your CREALITY Ender 3 by disconnecting it from the power for about 30 seconds.
15. Connection Confirmation: Upon restarting, the LCD will show that it's connecting. A successful connection will display an IP address assigned by your local DHCP server.
16. Accessing the Printer: Connect your computer to your home Wi-Fi network.
17. Printer Control Access: In your web browser, enter the IP address displayed on your printer's LCD screen to access the printer's control interface.

Always consult the official CREALITY Ender 3 documentation for the most accurate and up-to-date instructions. Improper modifications could cause damage, so proceed carefully.
