It includes:

• All five non-blocking stepper axes, parallel homing, travel limits, CAM/REL collision protection, and shared OBJ/CAR enable handling.
• Three smoothly moving servos.
• RGB PWM LED, NeoPixel, buzzer, debounced sample button, and filtered thermistor monitoring.
• Unified bounded serial-command parser supporting commands from both original sketches.
• Integrated latched STOP and RESUME.
• Full GPIO-conflict validation during startup.
• Thermistor sampling deferred during stepper motion to protect step-pulse timing.
• Compatibility functions retaining every named function from both uploaded files.
• All hardware, motion, timing, limit, and behavior configuration consolidated near the top.

The code passed GCC and Clang syntax checks plus a command-path smoke test. I could not compile it against a physical ESP32-S3 Arduino board package in this environment, so it should still receive a final compile and bench test using your exact board definition.

Build it with Arduino-ESP32 3.x and the Adafruit NeoPixel library. The sketch consumes six of the ESP32-S3’s eight LEDC channels. (Espressif Systems)

One important hardware warning remains: GPIO0, GPIO3, GPIO45, and GPIO46 are ESP32-S3 strapping pins, and all four are currently used by the combined pin map. External circuitry on them must not disturb their reset-time levels. (Espressif Systems)
