This is what i used to get my print up and going after reading every ones post…
4.2.2 board
Sprite Pro hot end
Home and bed probe position should be center.
Should be no boundary issues for mesh
Filament sensor was added
Using a Sonic Pad
# !Ender-3 V2 ABL
# printer_size: 220x220x250
# version: 3.6
# This file contains pin mappings for the stock 2020 Creality Ender-3 V2+CRtouch
# 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.

# [output_pin my_led]
# pin: PB12
# The pin to configure as an output. This parameter must be
# provided.
#pwm: False
# Set if the output pin should be capable of pulse-width-modulation.
# If this is true, the value fields should be between 0 and 1; if it
# is false the value fields should be either 0 or 1. The default is
# False.
#static_value:
# If this is set, then the pin is assigned to this value at startup
# and the pin can not be changed during runtime. A static pin uses
# slightly less ram in the micro-controller. The default is to use
# runtime configuration of pins.
#value:
# The value to initially set the pin to during MCU configuration.
# The default is 0 (for low voltage).
#shutdown_value:
# The value to set the pin to on an MCU shutdown event. The default
# is 0 (for low voltage).
#maximum_mcu_duration:
# The maximum duration a non-shutdown value may be driven by the MCU
# without an acknowledge from the host.
# If host can not keep up with an update, the MCU will shutdown
# and set all pins to their respective shutdown values.
# Default: 0 (disabled)
# Usual values are around 5 seconds.
#cycle_time: 0.100
# The amount of time (in seconds) per PWM cycle. It is recommended
# this be 10 milliseconds or greater when using software based PWM.
# The default is 0.100 seconds for pwm pins.
#hardware_pwm: False
# Enable this to use hardware PWM instead of software PWM. When
# using hardware PWM the actual cycle time is constrained by the
# implementation and may be significantly different than the
# requested cycle_time. The default is False.
#scale:
# This parameter can be used to alter how the 'value' and
# 'shutdown_value' parameters are interpreted for pwm pins. If
# provided, then the 'value' parameter should be between 0.0 and
# 'scale'. This may be useful when configuring a PWM pin that
# controls a stepper voltage reference. The 'scale' can be set to
# the equivalent stepper amperage if the PWM were fully enabled, and
# then the 'value' parameter can be specified using the desired
# amperage for the stepper. The default is to not scale the 'value'
# parameter.
