# Fysetc S6 v2.1 config for Voron V0.1 (and maybe others) This klipper configuration uses pin aliases. See below settings for the Fysetc S6 V2.1 menuconfig options that worked for me. ![make menuconfig: STM32F446, 32KiB bootloader, 12MHz crystal, USB on PA11/12](fysetc_s6_v2.1-make_menuconfig.png "make menuconfig screenshot") The S6 V2.1 can be flashed via `make flash FLASH_DEVICE=0483:df11` if you place a jumper connecting BOOT0 to 3.3V while it's powering up. Otherwise, you can also flash via microSD card. MBR partition table, FAT32. Make sure to name your new firmware image `firmware.bin` or else it won't flash. Ping `@clee#1337` on Discord if you have issues.
