Klipper config, ender 3 with 4.2.2 board (the noisy one), also with blouch , G29 (auto bed level)

kipper-ender3-4.2.2-bltouch-g29-g2-g3.cfg

# This file contains pin mappings for the stock 2020 Creality Ender 3
# with the 32-bit Creality 4.2.2 board. To use this config, during
# "make menuconfig" select the STM32F103 with a "28KiB bootloader" and
# serial (on USART1 PA10/PA9) communication.
# adapted for my printer ender3-4.2.2

# 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.

Does it work with the oem LCD screen ? and if i doesnt have bl touch installed?

Thank you for this! While I don't have a BL touch, your x/y/z mappings helped me immensely on my 2022 Ender 3 4.2.2 board with STM32F103 clone.

You should mention this config will work only the signal cables of bltouch installing in the Z axis, otherwise it doesn't.

To make it work with the 5 pin connector on creality v422 and 427 boards, in bltouch section, change sensor_pin: ^PA7 to sensor_pin: ^PB1. I think both of these config files should be in the Klipper configs directory but not sure how to get that done. good luck

The BLTouch sensor pin is actually located at ^PB1, not ^PA7. Still a great config nonetheless. Hope this helps somebody with the error "Failed to verify BLTouch probe is raised; retrying."
