* Make sure you are using the sensor cable(left=CONTROL_SERIAL_USART2 or right=CONTROL_SERIAL_USART3) selected in config.h
* Assuming RX or/and TX can be defective on your mainboard(port is defective on the MCU, 101 smd resistor is missing or has too high resistance), you can switch to other sensor cable in config.h
* On some boards the wire colors might differ, try switching blue and green wires
* Your Arduino TX/RX might not be working, you can verify that by trying with and FTDI and the Web tool to confirm the mainboard/firmware is not the issue
