## What it is
Optimized Marlin-based firmware for Creality Ender 3 V2 and S1 3D printers, with precompiled binaries for STM32 RET6/RCT6 boards. It adds features like BLTouch support, color themes, and calibration guides maintained by the community.

## Use cases
- replace stock firmware on an Ender 3 V2
- install custom firmware on an Ender 3 S1
- add BLTouch auto bed leveling to an Ender 3 V2
- get precompiled Marlin binaries for STM32 RET6/RCT6
- customize color themes on the Ender 3 V2 screen
- use an Ender 3 V2 with OctoPrint

## When to choose
- you own an Ender 3 V2 or S1 and want better features than stock firmware
- you want prebuilt binaries instead of compiling Marlin yourself
- you need BLTouch/3D touch probe support on these printers

## When to avoid
- you have a different 3D printer model
- you need a permissively licensed project (license is non-standard)
- you want to build generic Marlin for arbitrary boards

## Facets
- artifact type: application
- maturity: active
- function: embedded
- domain: hardware
- platform: embedded, cpp
- tags: 3d-printing, marlin-firmware, ender3, creality, 3d-printer-firmware, automation
