Klipper Configuration for the Fly-SB2040-V1 on USB

Edit me

Important: This guide assumes you have a working Klipper host installation on a Raspberry Pi or compatible device

Compile Klipper firmware for Fly-SB2040-V1

Tip: To read more about the KCONFIG_CONFIG option, see here

ssh to your klipper host console
cd to the klipper directory
```
cd ~/klipper
```

Run make clean

make clean KCONFIG_CONFIG=config.sb2040v1

Important: If when running the above command you get this output
Using default symbol values (no 'config.sb2040v1'). Configuration saved to 'config.sb2040v1'
Then you need to set all the correct settings when running make menuconfig below.
Otherwise, skip to compiling klipper.

Open menuconfig

make menuconfig KCONFIG_CONFIG=config.sb2040v1

Set the following settings
- [*] Enable extra low-level configuration options
- Micro-controller Architecture (Raspberry Pi RP2040)
- Bootloader offset (16KiB bootloader)
- Communication interface (USB)
- USB ids
- (gpio24) GPIO pins to set at micro-controller startup
  
  Klipper Menu Config USB
Quit and save the configuration

Run Make to compile the firmware

make KCONFIG_CONFIG=config.sb2040v1 -j4

Flash Klipper USB firmware with Katapult over USB

Look in your printer.cfg file and make note of the serial ID for your board.

Run the make flash command to flash the firmware

make KCONFIG_CONFIG=config.sb2040v1 flash FLASH_DEVICE= {Your serial ID here }

Example

make KCONFIG_CONFIG=config.sb2040v1 flash FLASH_DEVICE=/dev/serial/by-id/usb-katapult_stm32f407xb_170038000650314D35323820-if00 

Your Fly-SB2040-V1 should now have klipper firmware updated and be ready to use again.
