Hello, I can't get a connection I use the Manta M8P and since the pins

sda_pin: PC9 scl_pin: PA8

Firmware is flashed and the version is: v0.12.0-316-g96cceed23-dirty

the sensor is v1.3

don't know what to do next

markniu commented 1 month ago

how about use the probe pins: sda_pin: PD13 scl_pin: PD12

The same problem No data or corrupt data from BDsensor( ), Please check connection

does the light on while put a metal close the coil? check again the 5v and other wire order.

MDegelmann commented 1 month ago

111 / 5.000 Yes, the LED lights up when you hold a piece of metal to it.

I have checked all connections GND 5V SCL GND SDA

What does the cable that comes with the BDsensor look like?

MDegelmann commented 1 month ago

I measured the cable and everything has contact

markniu commented 1 month ago

it can not be measured by multimeter sometimes. what's the delay value in the BDsensor section? you can try to increase that value.

MDegelmann commented 1 month ago

I was able to solve the problem.

I flashed the sensor and now it works

BD Sensor V1.3 ST-Link V2 connected according to the wiki. I have checked the wiring multiple times.

When I connect everything the sensor lights up when I get it close to metal, so I think the sensor is working.

Using the BLTouch interface on my toolhead board. Getting 5V from another connector.

do you have the electronic schematic ? you can check if there is a capacitor on the PB6 on the board
