#
# Klipper configuration file for Anycubic i3 MEGA S
#
# This config file contains settings of all printer pins (steppers, sensors) for Anycubic i3 mega S in the factory configuration
# Klipper firmware should be compiled for the atmega2560
#
# Config file includes
#  - Original or 2208(2209) rotated by cabel 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
#
# Home position is determined by 3DTouch. Z limit switches are not used.
#
# The latest version of the config reference is also available online at:
# https://www.klipper3d.org/Config_Reference.html
