Progress LED Status Bar for Infimech TX / Flyingbear S1
LED status bar for a Klipper-controlled 3D printer, inspired by H2D.
Displays real-time printer state, print progress, and bed temperature.
The project works out-of-the-box — no changes to printer configuration required.
All effects and LED control are handled by a low-cost ESP32 board, keeping the setup simple and affordable.
Firmware & Source Code and more information: https://github.com/nezg/klipper-led-state
Minimum required components:
ESP32, ESP32-C3, or ESP32-S3 board (i use esp32 c3 - https://ali.click/q0zu41d)
Any 5V addressable LED strip (WS2812/NeoPixel compatible) (200led/m led strip - https://ali.click/wsyu41x)
Power supply for board and LED strip (5V, current depends on strip length, e.g., DC-DC 24V → 5V) (dc dc 24 -> 5v https://ali.click/y4zu41s)
4× magnets 8×2 mm
Installation (specific to these printers)
Power is taken directly from the printer board — there is a 16-pin connector with always-on 24V.
1. DC-DC input:
24V → DC-DC input (from 16-pin motherboard connector)
2. After DC-DC (5V):
+5V → LED + ESP32 (5V pin)
GND → LED + ESP32
3. Data signal:
ESP32 GPIO4 → LED DATA
