| # This file contains pin mappings for the NON stock 2020 Creality Ender 3 | |
| # 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. | |
| # adapted for my printer ender3-4.2.2 with some modifications and without the BLTouch. | |
| # 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. | |

I have the 256kb chip of (RCT6 instead of RET6). Do i need to make/load any changes? Creality 4.2.2 Ender 3 Pro. (CR touch changes are easy thanks to @luptonma. The latest Mainsail (from RaspPi imager) also has extra option at the Make Menu config. Any advise on these new options?
You should check schematics for your board. If pin names on the microcontroller are the same, you probably be fine. Also you can just go on and experiment with it, but be prepared for unforseen consequences.
BTW this config is a bit outdated. I've added some pretty neat macros and other stuff you guys probably don't need. I'll paste it ASAP.

Okay folks, here we go: new version of my config file, use with care!

Creality 4.2.2 Ender 3 Pro. (CR touch changes are easy thanks to @luptonma.
