BambuLED Autonomous WiFi Status & Progress Display

BambuLED ESP32 V2

An autonomous WiFi LED display system for Bambu Lab printers using an ESP32 and WS2812B LED strips.

No Raspberry Pi, no PC software running in the background, and no cloud service required. Simply connect the device to the same WiFi network as your Bambu Lab printers, configure your printers once, and the system works completely autonomously.

The device displays:

• Printer status
• Print progress
• Heating state
• Paused state
• Errors
• Finished prints
• Custom LED animations

The project is designed to be:

• Low cost (typically under €20 excluding printed parts)
