Thanks. Configs need to follow the guidelines at https://www.klipper3d.org/Example_Configs.html . At a minimum points 4, 6c, and 7.

The flash_usb.py script is only intended to flash USB targets - it isn't intended to flash over a serial port. If this printer needs to use stm32flash, then probably best to just describe how the user can run that tool in the printer.cfg comments.

The stm32flash uses the USB connection to the board. The board contains an onboard usb-to-serial and is connected to the serial interface of the STM32F103VET6. All communication is done via this USB.

Thanks. The config looks fine (though it would be preferable to state "enable usart(on pins x and y)" in the comments as opposed to saying "disable usb".

I don't agree with adding stm32flash support to flash_usb.py .

Cheers, -Kevin

Thanks. I merged this commit along with 6be0ba78 (in keeping with point 6b at https://www.klipper3d.org/Example_Configs.html ).

However, after I merged this, I realized the config should have a year in the filename (the approximate date the printer was purchased) as mentioned in point 2 of the above link.

Do you know what the approximate year of the printer is?
