BED_MESH_CALIBRATE Ender 3 Pro

Basic Information:

Printer Model: Ender 3 Pro
MCU / Printerboard: Creality 4.2.7
Host / SBC
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

Whenever I use bed mesh calibrate, hot end sends the probe off of the bed without even reaching the far corner of the lower left of the bed (If you are facing the printer from the front). Below is my Printer.cfg file, can someone please help me.

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

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.

Agree to @LifeOfBrian

Without using that format, spaces and special characters get lost and the code is useless.
