Ender 3 Pro config with Creality 4.2.7, TH3D EZABL, Sprite Extruder

printer.cfg

# This file came from https://github.com/Klipper3d/klipper/blob/master/config/generic-creality-v4.2.7.cfg

# 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.

# 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.

# Heath: I copied the firmware to an SD card and rebooted the printer. 
# The printer LCD will not give any indication that the firmware update was successful.

# My hardware:
#  - Ender 3 Pro
#  - Creality silent board 4.2.7
#  - Creality Sprite pro Extruder / Hotend
#  - Th3d EZABL

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

# these are needed by mainsail macros

Hi, IIRC, I list the hardware I use in the comments at the top. So if your hardware matches that then this should work. I've never had a CR touch, so you'll have to get that config from elsewhere. Additionally, when using the CR Touch, I think you need macros to deploy and retract the probe. There should be examples of this in the klipper GitHub config folder. It has lots of examples, just pull the pieces you need from them. This file does not go on the printer. It goes in the config folder of the klipper install on your host. You can edit it directly on the host or by mailsail or fluidd, whichever you installed. Follow the steps in the klipper config page to get each part configured and tested before you try to print. The docs will guide you to get the mechanics working, then the hot end and the extruder. And then configure your probe and leveling. Be patient. It will take some trial and error to get things perfect. It will be worth it. Good luck.

I installed Linux Mint on an old laptop and I believe I have it all set but I need this printer.cfg file to install on the printer itself I believe is how it works? I have an Ender 3 Pro with a v4.2.7 board, the creality cr touch and the sprite extruder. Is this the exact file I am missing?
