Ender 3 S1 Pro
Raspberri Pi 5 running Klipper
Custom BL Touch extension: https://cults3d.com/en/3d-model/tool/ender-3-s1-pro-4020-fan-cr-touch-no-y-offset
Hi everyone.
I tried to run an auto bed mesh leveling on my ender, after adjust the screews, with the native tool, without any goals. The mesh seams to be a little warp, and if I try to print a bed leveling test for the whole bed space, it look in some parts to high and other parts too low.
Any help to reach a good bed mesh?
I was thinking about to buying a glass bed, in order to have a perfect flat bed, or to change manual the mesh.
Here my printer.cfg:
# This file contains pin mappings for the stock 2021 Creality Ender 3
# S1 & S1 Pro. To use this config, check the STM32 Chip on the
# Mainboard, during "make menuconfig" select accordingly either the
# STM32F103 with "28KiB bootloader" or the STM32F401 with
# "64KiB bootloader" and serial (on USART1 PA10/PA9) for both.
# For a direct serial connection, in "make menuconfig" select
# "Enable extra low-level configuration options" and Serial
# (on USART2 PA3/PA2), which is 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 filename
# must be changed to "firmware.bin"
# With STM32F401, you might need to put "firmware.bin" in a
# folder on the SD card called "STM32F4_UPDATE" in order to flash.
# See docs/Config_Reference.md for a description of parameters.
