# This file is originally from https://github.com/Klipper3d/klipper/blob/master/config/printer-elegoo-neptune2-2021.cfg

# Paste here and save your klipper configuration
# This file contains standard pin mappings for the stock Elegoo Neptune 2 with a
# ZNP Robin Nano (v 1.2 and v1.3) board.
# For the 1.2 board:
#   - Compile with the processor model STM32F103.
#   - Enable "extra low-level configuration options"
#   - Select the 28KiB bootloader,
#   - Select (Serial (on # USART3 PB11/PB10) for the communication interface.
# Note that the "make flash" command does not work with ZNP Robin boards. After
# running "make", run the following command:
# ./scripts/update_mks_robin.py out/klipper.bin out/elegoo.bin
# 
# For the 1.3 board:
#   - Compile with the processor model STM32F407.
#   - Enable "extra low-level configuration options"
#   - Select the 32KiB bootloader,
#   - Select (Serial (on # USART3 PB11/PB10) for the communication interface.
# Note that the "make flash" command does not work with ZNP Robin boards. After
# running "make", run the following command:
# cp out/klipper.bin out/elegoo.bin
# 
# Copy the file out/elegoo.bin to an SD card and then restart the printer with
# that SD card.
# See docs/Config_Reference.md for a description of parameters.
