Klipper MK3S/+ Config including optional Bondtech Extruder, Bear Extruder, etc.

printer-prusa-mk3s-2021.cfg

# This file contains pin mappings and reasonable defaults for Prusa i3 MK3S
# printers. It will work with MK3 (non-S) by selecting the alternative filament
# sensor. References to common community mods are included as well.
#
# Note: The Einsy boards sold by Prusa have defective firmware on the
# usb-to-serial chip that makes the boards unusable with Klipper through USB.
# While flashing Klipper firmware must be done over USB, the board can be used
# via serial with no additional modification.
#
# To use this config, the firmware should be compiled for the AVR atmega2560.
# To use via serial, in "make menuconfig" select "Enable extra low-level configuration options"
# and select serial1 (the RasPi serial) or serial2 (MMU port on exp3) when making
# the mcu firmware. See
# https://reprap.org/mediawiki/images/6/6d/EinsyRambo1.1-connectors-j19-p1-p2-p3.png
# for pinouts when wiring.
#
# It is also possible to fix this issue with no ill effect if reverting to non-Klipper
# firmware. See https://github.com/PrusaOwners/mk3-32u2-firmware
# Boards sold by Ultimaker as wel as some clones do not have this problem.
#
# See the example.cfg file for a description of all available parameters.
