printer-20230307_011119.cfg

# This file contains pin mappings for the LDO Kit using BigTreeTech Octopus V1 as the main controller.
# To use this config, the firmware should be compiled for the STM32F446 with a "32KiB bootloader"
# Enable "extra low-level configuration options" and select the "12MHz crystal" as clock reference

# after running "make", copy the generated "klipper/out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the Octopus with that SD card.

# See docs/Config_Reference.md for a description of parameters.
