4.2.2_printer.cfg

#====================================================================
# USE AT YOUR OWN RISK
#====================================================================

# All I have done was swap the pins for the 4.2.2 board.
# I have not tested this configuration. 

# Change file name from 4.2.2_printer.cfg to printer.cfg 
# and place in the folder you are running Klipper from.

# This file is for a modified Ender 3v2 with Sprite Pro Extruder,
# CR Touch, with a 4.2.2 board.

#This configuration uses KAMP.

# Klipper Adaptive Meshing and Purge Line files are included.
# Add those to the folder you are running Klipper from.
# MORE INFO ON KAMP GITHUB

#To use this config, during "make menuconfig" select the
# STM32F103 with a "28KiB bootloader" and serial (on USART1 PA10/PA9)
# communication.

# It should be noted that newer variations of this printer shipping in
# 2022 may have GD32F103 chips installed and not STM32F103. You may
# have to inspect the mainboard to ascertain which one you have. If it
# is the GD32F103 then please select Disable SWD at startup in the
# "make menuconfig" along with the same settings for STM32F103.

# 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.

# Replace the slicer's custom start and end g-code scripts with
# START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0} 
# and END_PRINT.

# at you own risk.

#====================================================================
# INPUT SHAPER
#====================================================================

# Klipper supports Input Shaping - a technique that can be used to
# reduce ringing (also known as echoing, ghosting or rippling) in
# prints. Ringing is a surface printing defect when, typically,
# elements like edges repeat themselves on a printed surface as a
# subtle 'echo':

# Every printer is different and the ringing frequency depends on
# the printer's mechanical properties. The ringing frequency can be
# measured by printing a simple test object and measuring the
# distance between the echoes. The ringing frequency is typically
# between 50 and 100 Hz.

# https://www.klipper3d.org/Resonance_Compensation.html

# Uncomment the following lines to enable input shaping. The
# shaper_freq_x and shaper_freq_y parameters should be set to the
# ringing frequency of the printer.

# This will help ensure that your machine performs optimally and
