Klipper printer.cfg file for Anycubic i3 Mega w/ BLTouch bed mesh leveling, input shaper (resonance compensation), pressure advance and skew correction.

Anycubic_i3_Mega_Klipper_printer.cfg

# This file contains pin mappings for the Anycubic i3 Mega with
# Ultrabase from 2017. (This config may work on an Anycubic i3 Mega v1
# prior to the Ultrabase if you comment out the definition of the
# endstop_pin in the stepper_z1 section.) To use this config, the
# firmware should be compiled for the AVR atmega2560.

# See the example.cfg file for a description of available parameters.
