printer-creality-ender3-2018.cfg

# This file contains common pin mappings for the 2018 Creality
# Ender 3. To use this config, the firmware should be compiled for the
# AVR atmega1284p.

# Note, a number of Melzi boards are shipped without a bootloader. In
# that case, an external programmer will be needed to flash a
# bootloader to the board (for example, see
# http://www.instructables.com/id/Flashing-a-Bootloader-to-the-CR-10/
# ). Once that is done, one should be able to use the standard "make
# flash" command to flash Klipper.

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