ender 6 btt octopus board klipper config from reddit

qakcd4.ender_6_bigtreetech_octopus_klipper_config

Following on from my post about my BTT SKR 2 and Klipper config, I present to you my BTT Octopus + Klipper config for my Ender 6.

I upgraded from the SKR 2 to Octopus because my SKR 2 was one of the first batch with the defect, and I aso liked the additional connections available on the Octopus.

# This file contains common pin mappings for the BigTreeTech Octopus V1 + Ender 6.
# 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.

# The "make flash" command does not work on the Octopus. 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 Octopus
# with that SD card.

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

# pressure_advance = <start> + <measured_height> * <factor>

# pressure_advance: 0.76
#   The amount of raw filament to push into the extruder during
#   extruder acceleration. An equal amount of filament is retracted
#   during deceleration. It is measured in millimeters per
#   millimeter/second. The default is 0, which disables pressure
#   advance.
#pressure_advance_smooth_time: 0.040
#   A time range (in seconds) to use when calculating the average
#   extruder velocity for pressure advance. A larger value results in
#   smoother extruder movements. This parameter may not exceed 200ms.
#   This setting only applies if pressure_advance is non-zero. The
#   default is 0.040 (40 milliseconds).
