hello

i use marlin Marlin-2.1.2.5 with ramps 1.4 and arduino board


i order and "DollaTek Transparent Car Bed Leveling Sensor For 3D Printer Part Enhances Printing Precision"
[www.amazon.nl]

i connect green wire to pin11
when i connect power supply from usb port to arduino board self-test is start on load
in bltouch menu "deploy" "stow" and "self-test" not working
and i use this commands but not working

M280 P0 S10  ; (Deploy)
M280 P0 S90  ; (Stow)
M280 P0 S120 ; Self-test
M280 P0 S160 ; Reset alarm

i activate this options


Configuration.h

#define ENDSTOPPULLUP_XMIN
#define ENDSTOPPULLUP_YMIN
#define ENDSTOPPULLUP_ZMIN
#define ENDSTOPPULLUP_ZMIN_PROBE
  
#define X_MIN_ENDSTOP_INVERTING true // Set to true to invert the logic of the endstop.
#define Y_MIN_ENDSTOP_INVERTING true // Set to true to invert the logic of the endstop.
  
#define USE_PROBE_FOR_Z_HOMING

#define BLTOUCH

#define INVERT_X_DIR false
#define INVERT_Y_DIR false
#define INVERT_Z_DIR true

#define AUTO_BED_LEVELING_BILINEAR

#define Z_SAFE_HOMING

Configuration_adv.h

#define BLTOUCH_FORCE_SW_MODE
#define BABYSTEPPING

what is the problem?

Disable BLTOUCH_FORCE_SW_MODE

The 3d touch is a cheap clone of the bltouch and does not support any advanced bltouch features.

Also be warned, these 3d touches have a horrible reputation of only lasting a few weeks
