Initial Setup

1. Clone the repositories:

# Create base directory
mkdir ~/3d_printing
cd ~/3d_printing

# Clone Marlin
git clone -b bugfix-2.1.x https://github.com/MarlinFirmware/Marlin.git Marlin-2.1.x

# Clone configurations
git clone https://github.com/yourusername/ender-bender-firmware.git

2. Link configurations:

# Create symbolic link to configurations
cd Marlin-2.1.x/Marlin
ln -s ../../ender-bender-firmware/configs config

# Verify the link
ls -la config

File Origins

• From Marlin Repository:

  • Configuration.h - Base configuration file
  • Configuration_adv.h - Advanced configuration file
  • Marlin.ino - Main Marlin sketch
  • platformio.ini - Build configuration (we modify this)

• Generated During Build:

  • Configuration_override.h - Created from your INI file

• From Your Repository:

  • All files in ender-bender-firmware
  • INI configuration files
  • Documentation

Use PlatformIO to Compile Firmware

1. See PlatformIO Setup

Configuration Management

• Keep configurations in the config subdirectory
• The path in platformio.ini is relative to the Marlin directory

Create Configuration Override

Create a new file Configuration_override.h:

#pragma once

// This file is automatically generated from the INI config
// Do not edit this file directly

#include "config.h"
