# 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 with a bootloader that # requires the following command to flash the board: # avrdude -p atmega1284p -c arduino -b 57600 -P /dev/ttyUSB0 -U out/klipper.elf.hex # If the above command does not work and "make flash" does not work # then one may need to flash a bootloader to the board - see the # Klipper docs/Bootloaders.md file for more information. # See docs/Config_Reference.md for a description of parameters.
