Klipper Config

jefflarkin-i3-mega-s-printer.cfg

# 
# Klipper configuration file for Anycubic i3 MEGA S
#
# This config file contains settings of all printer pins (steppers, sensors) for Anycubic i3 mega S with TMC2208 Drivers with stock plug orientation 
# Klipper firmware should be compiled for the atmega2560
#
# Config file includes
#  - Original or 2208(2209) rotated by cable drivers
#  - Mesh bed leveling: BLtouch (3DTouch sensor from Triangelab)
#  - Manual meshed bed leveling (commented out)
#  - 'virtual_sdcard' for fast printing without gaps
#  - Beeper through M300 gcode
#  - Pause/Resume through M600 for filament change
#  - START_PRINT/END_PRINT macros should be start and end g-code in slicer
#  - Pressure Advance and Input Shaper configured
#
# 3DTouch code is commented out. Z limit switches are used to home Z axis.
#
# Video covering installation here: https://youtu.be/cAxEIdThDiQ
#
# The latest version of the config reference is also available online at:
