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

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
