# This file contains common pin mappings for the BigTreeTech Octopus V1. # 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. ## Voron Design VORON2 250/300/350mm BigTreeTech OctoPus V1 TMC2209 UART config ## *** THINGS TO CHANGE/CHECK: *** ## MCU paths [mcu] section ## Thermistor types [extruder] and [heater_bed] sections -
