ok, update firmware to 1.1.0.1 and works it. i try the old version rc 5 and rc 7 and work too. here my mistake i did.
my sensor its npn no 6v-36v and a ramps 1.4 board.
first mix up firmware board from 13efb to 14efb
powering the sensor with a separate power supply.
i use a 1n4001 diode to send signal to the arduino, the resistor didn't not work , i use the wrong K-hom my reading was 3.9v high to 0 low
what i changed on the firmware: this its firmware 1.1.0.1 below
