problem with M119

[tjengbudi]

hello i connected bd sensor to my skr 1.4 i using bltouch port from the board. but cause the probing is cannot works i connect it to exp1 port. for sure i connect it to port p1.27

the schematic is right here https://user-images.githubusercontent.com/74151066/98479426-84961880-21f7-11eb-8f3c-1270e7dc9f71.png

my settimg is

[BDsensor] sda_pin: P1.27 scl_pin: P2.0 delay: 20 z_offset:0 x_offset: 0 y_offset: 34 position_endstop: 0.5 value is 0.5~1.0 collision_homing:0 collision_calibrate:0

M119 always return z: open when i added metal under the sensor the light is on. but the M119 still said z:Open

M102 s-1 BDsensorVer:V1.2c pandapi3d ,switch_mode=1,collision_homing=0,collision_cal=0

m102 s-2 3.01mm

i checked cable with multitester it is not broken at all

installed newest bdsensor script and klipper last version.

so i do not understand why this happened

did you calibrate the BDsensor? you can calibrate the sensor again.

[tjengbudi]

did you calibrate the BDsensor? you can calibrate the sensor again.

already calibrate, calling m102 s-5 lowest value is 55

calibrate again after you asked and after calibrate m102 s-5 lowest value is 53

and it is still not triggered the z endstop even with LED in bdsensor ON

the strange is, it always in OPEN state.

i trying to change sda pin with random pin in the board but i not connect it to bd sensor. i want to make sure that i might have wrong connection. or cable error.

after restart, command m102 s-1 replied "No data or corrupt data from BDsensor(), Please check connection" so i am sure that i have connect it in the right pin and working

change it back and it replied "BDsensorVer:V1.2c pandapi3d ,switch_mode=1,collision_homing=0,collision_cal=0"

must i flash it?

i use screw for the test looks like i do it wrong. test with wider dimension it triggered..

thankyou
