# Ender 3 Pro (2018)
# BIGTREETECH SKR mini E3 v3.0
# Creality Sprite Extruder Pro
# Antclabs BL Touch (Genuine)
# Raspberry Pi (Mainsail OS)
# ALPHA V0.1 06/18/2023

# Made by CEADD - ceadd.ca
# Special thanks to bigtreetech, jamesh1978 and nopp

# To use this config, the firmware should be compiled for the
# STM32G0B1 with a "8KiB bootloader" and USB communication.

# The "make flash" command does not work on the SKR mini E3. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the SKR
# mini E3 with that SD card.
