This is mostly for my own reference but it may help someone in need. The 3D Touch finally works after a lot of trial and error.

Important settings:

stow_on_each_sample: True
probe_with_touch_mode: False
pin_up_touch_mode_reports_triggered: False

The last line is set to false even though the Klipper test reports true!
You may need to try a combo of true and false of these settings.
I’ve seen other threads set pin_up_touch_mode_reports_triggered to true to get it working depending on the model.
stow_on_each_sample is slower but it doesn’t work as well otherwise.

Here’s what it looks like when NOT working:

Some keywords: 3D Touch not working, blinking fast. BL Touch Clone (3D Touch) fails calibration. Red Blink. Blue Blink.

Here’s my entire printer.cfg  — keep in mind it has pressure advance, bed leveling, etc. custom settings.

# This file contains pin mappings for the stock 2020 Creality Ender 3
# V2. To use this config, during “make menuconfig” select the
# STM32F103 with a “28KiB bootloader” and serial (on USART1 PA10/PA9)
# communication.

 

# If you prefer a direct serial connection, in “make menuconfig”
# select “Enable extra low-level configuration options” and select
# serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC
# cable used for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC

 

# Flash this firmware by copying “out/klipper.bin” to a SD card and
# turning on the printer with the card inserted. The firmware
# filename must end in “.bin” and must not match the last filename
# that was flashed.

 

# See docs/Config_Reference.md for a description of parameters.
