Ender 3 with v4.2.2

[Finnian68]

Cannot find a klipper config for Ender 3 with Creality v4.2.2 board and STM32F103 RET6 mcu. I tried using the v4.2.1 config, but after uploading to Mainsail, Klipper is reporting "Unable to open config file /home/pi/printer_data/config/printer.cfg". I have verified the presence and permissions of the file using WinSCP. Restarting the firmware or the Pi have no effect.

Pls Post a screenshot from the config files panel in mainsail

It has the wrong extension. Your file is named printer.conf but it should be printer.cfg.

This was the issue with Klipper not reading the file. Is there any specific config file for the v4.2.2 board, or is the v4.2.1 file the same? I see differences between the v4.2.1 and v4.2.7 "generic" files, And with the "printer-creality-ender3" files, none of them seem to be for my printer.

sry... there are so many tiny differents between ender3 and ender3 and creality boards... i dont know these. you can only check all ender3 config files and/or creality config files, or try to find a schematic of both boards in the internet.

To wrap it up, for the plain Ender 3 with Creality v4.2.2 board (STM32F103 RET6 mcu), the Klipper printer config file that seems to work is "printer-creality-ender3pro-2020".

there are only small changes between "normal" and "pro". magnetic bed, other Y rail and fan from the power supply on a different position.

but from the normal ender 3, there was also a "silent" version. i think this could be your version. the silent board could be just the same as the ender 3 pro board.

there should not be any difference in the config between ender 3 and ender 3 pro other then the board itself. sizes and "electrical features" look like the same in both models.
