Klipper config for my ANET A8

printer.cfg

# This file contains common pin mappings for Anet A8 printer from 2016
# and 2017. To use this config, the firmware should be compiled for
# the AVR atmega1284p.

# Note that the "make flash" command does not work with Anet boards -
# the boards are typically flashed with this command:
#  avrdude -p atmega1284p -c arduino -b 57600 -P /dev/ttyUSB0 -U out/klipper.elf.hex

# See docs/Config_Reference.md for a description of parameters.
