# 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.

##  Update value below when you perform extruder calibration
##  If you ask for 100mm of filament, but in reality it is 98mm:
##  rotation_distance = <previous_rotation_distance> * <actual_extrude_distance> / 100
##  22.6789511 is a good starting point
##  Rotation_distance is the amount of distance the filament travels for one full rotation of the stepper motor
##  Lowering this value extrudes more (over extrudes) while raising it extrudes less (under extrudes).

rotation_distance: 22.1664068
#rotation_distance: 18.745   #Bondtech 5mm Drive Gears - Stealthburner calibrated was 14.29 short and measured 5.71mm or 85.71 extruded vs 100.
#rotation_distance: 16.066   #Bondtech 5mm Drive Gears - Stealthburner calibrated went OVER 120mm and line disappeared. even MORE SHORT, WRONG DIRECTION to go lower, needs higher
#rotation_distance: 19.665   #Bondtech 5mm Drive Gears - Stealthburner calibrated
##  Update Gear Ratio depending on your Extruder Type
##  Use 50:17 for Afterburner/Clockwork (BMG Gear Ratio)
##  Use 80:20 for M4, M3.1
