printer.cfg

# This file is for a modified Ender 3v2 with Sprite Pro Extruder,
# CR Touch, with a 4.2.7 silent board. Klipper and Mainsail are
# installed on a Raspberry Pi 3B+ 4GB and Raspberry Pi 4B+ 4GB. 

# 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
# https://github.com/kyleisah/Klipper-Adaptive-Meshing-Purging

# This file contains pin mappings for the Creality "v4.2.7" board. 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.

# 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.

# 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.

# To avoid any potential errors, it's best to include the

# Additionally, it's highly recommended that you tune your own PID
#  values and set the z-offset before starting any printing tasks.
# This will help ensure that your machine performs optimally and 
# that you achieve the best possible results.
