Ender 3 Pro Creality 4.2.7 with bltouch - Klipper printer Configuration

printer.conf

# 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.

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

[include mainsail.cfg]

Thank you so much it worked

i was just wondering if you could give me your maisail.cfg too im using octoklipper and it doesn't give me one

I haven't used this in quite a while; I've upgraded to Prusa printers, so I don't have the configs anymore.

Thank you so much, couldn't fins printer.cfg for 4.2.7. That was what i needed.

@Ruddiest i can give you my file if you still need that.

@atasuhindol i know its kinda late but if you could

@Ruddiest, here you go buddy.

I replaced a 4.2.2 board with 4.2.7, caught out and confused by the pin changes. thanks for this top google result my friend.

Bro! you are a life saver. I could not find those pin names to same my life! I just needed to comment out the [board_pins] section and it seems to be working

For a reason I don't know, I had to use sensor_pin: ^PA7 instead of sensor_pin: ^PB1 for the bltouch

I have no clue what I'm doing I put everything in on this and it says that I need a second aliases and I don't know what the mailsail is or how to get it. If someone could please help me.

Klipper warnings found.
