Requirements

In order to use this firmware, your printer must meet the following requirements:

• A compatible control board: Creality 4.2.2, 4.2.3, 4.2.7, V24S1_301 or SKR Mini E3 V3 for Ender series printers with a STM32F103 or STM32F401 SoC.
• A DWIN, DACAI, TJC or SYNWIT color display with encoder knob. Touch or legacy monochrome screens are not supported.

You can modify your printer to meet these requirements.

Versions and binary name nomenclature

• Ender 3v2 MM: if you have the Ender 3v2 near to stock then use this version (Manual Mesh).
• Ender 3v2 BLT: use this version if you installed a CR/3D/BLTouch level sensor in the Ender 3v2.
• Ender 3S1: use this version if you have an Ender 3S1 printer with CRTouch, (F1 is for the STM32F103 and F4 is for the STM32F401 SoC)

You can download the latest binaries from the assets at the bottom of the release page. To know if you have the last release go to the info page in the display of your printer and compare the release build date with the name of the binary file.

MM - Firmware for Manual Mesh, use it if you don't have a probe.
BLT - BL/3D/CR Touch probe support.
UBL - Unified Bed Leveling
T13 - Marlin #13 temperature sensor (like Sprite Pro Extruder)
IS - Input Shaping
LA - Linear Advance
MPC - Model Predictive Temperature Control
CVLM - CV Laser Module
EZABL - support the "EZABL Pro" probe from TH3D Studio

The filename follows the convention:

Ender3V2-422-MM-YYYYMMDD.bin

Where YYYYMMDD indicates the date of the build. 422 refers to the mainboard version 4.2.2, 423 refers to the mainboard version 4.2.3, and 427 is for the 4.2.7 mainboard version, if you got a 4.3.1 board use the 422 version. SKRMINI version is currently for the BTT SKR Mini E3 V3 board (needs a screen adapter).

For example, if you want a firmware for your Ender-3 V2 printer with a control board version 4.2.2, CRTouch and support for UBL, you should download the file:

Ender3V2-422-BLTUBL-YYYYMMDD.bin

Preliminary DEMO support for monochrome and MarlinUI touch screens

This release includes support for additional displays units with the Marlin ULTIPANEL mode.

Precompiled firmware

Due to the inability to test many firmware variants, the public free pre-compiled binaries will be released when its testing phase is complete to ensure a quality release.

Demo builds are available for test here: https://github.com/mriscoc/Special_Configurations/releases/tag/demo
