The BambuFlag is an application designed display a Bambu X1 3D printer status. Using WiFi and MQTT protocols to monitor the printer's status and control a servo that moves some flags.

• ESP32 board: https://amzn.eu/d/gnoAfbd
• Servo https://amzn.eu/d/5UxaUpT
• Wires: https://amzn.eu/d/bfbP5ST

• BambuFlag: https://makerworld.com/en/models/594156#profileId-515995

• WiFi and MQTT Connectivity: Connects to a local WiFi network and communicates with the printer via MQTT
• Servo Control: Activates a servo to show printer statuses
• Web Server: Hosts a web server to provide manual control and configuration of the system
• Stage Monitoring: Monitors various stages of the printer to determine when to activate the motor

In the case of having to change the boundaries of the motor they can be changed and saved into the eeprom memory of the chip from the Setting landing page:

Enter your WiFi and MQTT credentials in the following variables:

// WiFi credentials
char ssid[40] = "your-ssid";
char password[40] = "your-password";

// MQTT credentials
char mqtt_server[40] = "your-bambu-printer-ip";
char mqtt_password[30] = "your-bambu-printer-accesscode";
char serial_number[20] = "your-bambu-printer-serial-number";

• ssid is your WIFI name
• password is the WIFI password
• mqtt_server is your Bambu Printers IP address
• mqtt_password is your Bambu printer access code as found on your printer
• serial_number is your Bambu printer serial number as found on your printer

The application uses the following GPIO pin for the servo:

int pinServo = 27;

1. Connect the ESP32 to your computer.
2. Open the code in the Arduino IDE.
3. Enter your WiFi and MQTT credentials in the respective variables.
4. Upload the code to the ESP32.
5. Access the web server via the IP address assigned to the ESP32 to configure and control the application.

Connect servo to ESP32 poles acordingly and the control pin into the GPIO27. Connection from the servo into the board is done using 3 male-female DuPont cables.

The application hosts a web server to provide manual control and configuration. Access the following URLs for different functionalities:
