  • Preheat hotend menu for Prepare/Filament management menu
  • Mesh Leveling progress viewer
  • Added PETG Preheat in precompiled versions (Current source supports 10 material preheats)
  • And many improvements and fixes

From Marlin 2.1.2

  • More SCURVE cycles on unoptimized cortex-m0 (#24955)
  • Fix G-code resend race condition
  • G30 move to logical XY (#24953)
  • and many more fixes from latest bugfix 2.1.x

This firmware is based on Marlin, has been optimized and has enhancements for the Creality Ender 3 V2/S1 printer. This is an universal firmware that can be used in both RET6 and RCT6 STM32FX chips that have 256k or 512k Flash memory.

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_301F1, V24S1_301F4 or SKR Mini E3_V3 for Ender series printers with a STM32 SoC.
  • A DWIN or DACAI color screen with encoder knob. Touch screens are not supported.

You can modify your printer to meet these requirements.


  • 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

UBL versions

Binaries with UBL in their filename have support for Marlin Unified Bed Leveling, this system is similar to the bilinear leveling but with a few extra features to provide users with more control. There are multiple guides on the web about UBL, we recommend reading about it before using this new leveling system.

Model Predictive Temperature Control (MPC)

From this version MPC is being incorporated in all versions. MPC has proven to be a better algorithm for keeping the nozzle temperature stable, and is also very useful for high power heaters.

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. The filename follows the convention:


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
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:
