Installed on Ender 6 with Klipper, all went fine but no distance measurement.
I2C seems to work (based on M102-S-1).
Started M102 S-6 with very small distance from metal bed. Bed goes down in small steps, but calibration data shows no measurement results.
Not sure what to do now. Is my BDsensor simply defective or is there someting else to look for?

Hi Mark,
After it did not work I was not quite sure, and tried both sides. I use a magnetic bed so it should work. I double-checked by holding the flat surface of an iron wrench against each side. There was no LED response. That, in combination with the communication for the ID string working fine, is how I concluded that the BDSensor is likely defective.
I would really like to use the device. So far I use a BLtouch and it is fooled by the magnetic bed. The reading is too different for the center and the sides. A ruler and feeler gauge show that the build surface is flat and that the gantry is straight. The BLTouch reports it as curved. I edit that out in the configuration file after calibration, that kind of defeats most of the purpose of the thing.
This is the sensor that I have trouble with.
hello, did the led light on and off while it close or far away the bed? what's delay value in the section BDsensor? seems the returnd version is not completed. could you take picture of the sensor about the hardware version. you can open the shell and check the connection inside if is it v1.3 2023.12
