Marlin 3D Printer Firmware for Ender 3

This is my personal version of Marlin 1.1.x for the Creality Ender 3 (Pro), based of Vanilla Marlin 1.1.9 bugfix. It features support for thermal runaway protection, BL Touch (2.0), SD card and advanced pause features (like filament change with M600). But loses a couple of other features.

The current code is made for the silent 1.1.4/1.1.5 board by Creality, with the official BL touch kit installed.

Based on the vanilla Marlin code over at MarlinFirmware/Marlin

Enabled Features

• Thermal runaway protection
• BL touch version 2.0 (with offsets for the official kit
• SD Support
• Advanced pause features, allowing for changing filament mid print
• Slim LCD Menus
• TMC2088 Standalone drivers (for the official silent main board

Disabled Features

• Some LCD features (SLIM_LCD_MENUS is enabled)
• "About Printer" on the LCD
• Arc support (currently unused by all major slicers, including Cura and Simplify3D)
• Scrolling of long text
• Volumetrics features
• Workspace offsets (homing offsets)

Flashing the Ender 3

1. Install the Arduino IDE
2. Install the custom Sanguino boards using the board manager using this additional boards manager URL: https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
3. Install the U8glib library using the libraries manager (you might need to scroll down)
4. Make sure you have a bootloader burned on your board (the silent 1.1.4 has a bootloader by default): https://www.youtube.com/watch?v=fIl5X2ffdyo
5. Open Marlin.ino from this repository and press upload in the Arduino IDE
6. Initialize the EEPROM for the LCD menu
