# To create the Firmware you need to use the following configuration:
#     - Micro-controller: STM32
#     - Processor model: STM32F103
#     - Bootloader offset: 32KiB
#     - Communication interface: Serial (on USART1 PA10/PA9)
#
# To install the Firmware rename the klipper bin to `main_board_20xxxxxx.bin`
# and copy it to an SD Card.
# Power off the Printer, insert the SD Card and power it on.
# It should beep several times and the LCD should be stuck on the Splash screen.
# Now you should be able to connect to the Printer, you might need to change
# the mcu/serial setting in this config according to your set up.
#
# If you want to revert the Firmware back to Marlin you simply need to flash it
# with a anycubic firmware through the SD Card

# note: this config is a modified version of the Anycubic Vyper configuration
# from the main Klipper repository.
# the default configuration does NOT work, so i've tried adjusting it with
# other values found in any repository i could find which has one.
