  1. # This file contains common pin mappings for the BigTreeTech OctoPus V1.
  2. # To use this config, the firmware should be compiled for the STM32F446 with a "32KiB bootloader"
  3. # Enable "extra low-level configuration options" and select the "12MHz crystal" as clock reference
  4.  
  5. # after running "make", copy the generated "klipper/out/klipper.bin" file to a
  6. # file named "firmware.bin" on an SD card and then restart the OctoPus with that SD card.
  7.  
  8. # See docs/Config_Reference.md for a description of parameters.
