Note: Due to lack of program memory space in the STM32F401RCT6 SoC some standard feature had to be removed for the F4 UBL firmware version, for example: BAUD_RATE_GCODE, INDIVIDUAL_AXIS_HOMING_SUBMENU, SOUND_MENU_ITEM, LONG_FILENAME_WRITE_SUPPORT, BINARY_FILE_TRANSFER, POWER_LOSS_RECOVERY.

Main topics

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.

ProUI_ed-in-Touchscreen.mp4

ProUI_ex-in-Ender3.mp4

Special versions

There are several special configurations here: https://github.com/mriscoc/Special_Configurations/releases

Compiling your firmware flavor

We do not provide basic support on compiling the source code, please refer to the many places on the web for how to compile the Marlin firmware. Custom firmware can be build using the Configurator and following the guidelines in the Special Configurations repository:

Community links

Donations

Thank you for your support, I receive donations through Patreon and Paypal

Precompiled firmware

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