factory_printer.cfg

# !Ender-3 Pro
# printer_size: 220x220x250
# version: 3.5
# This file contains pin mappings for the stock 2020 Creality Ender 3
# Pro 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.

# 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

# 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.
