MAY 2023

What's new in this release

• Runout icon indicator over the Extruder flow dashboard icon.
• Dashboard Speed shows the current axes speed in mm/s intermittently with the speed percentage
• Enhanced preview with arbitrary thumbnail size
• Preview QR code removed for improve support with some display units
• Improved 3D/BL/CRTouch auto leveling
• Enable BLTouch HS mode for bed tramming wizard
• Set Multiple probing to 0 as default
• Better limits for mesh insets editing
• New C35 custom g-code for launch the bed tramming wizard.
• Added toolbar option for parking head.
• Force axes homing to allow parking at pause
• Raise Z when printing is aborted
• Fix a possible bug with filename drawing in printing page
• Fix Crash after removing SD card #894
• Several minor bug fixes and Misc. optimizations
• and many more fixes from latest Marlin's bugfix 2.1.x
• In source (need a custom build):

TJC support to enable preview and grid mesh viewer Added Creality CV laser module support with automatic file type detection Added Creality Cloud Support Menu items value faster/smooth change rate More #define flags to disable features to help to reduce code size Many improvements from the latest Marlin's bugfix sources Note1: In latest releases I'm promoting UBL versions over ABL, but ABL versions will be available through custom compile. If you had a G29 to make an ABL leveling before each print change it to G29 P1 for UBL. MPC is also being incorporated in replacement of the hot-end PID which will continue to be available on custom compiles.

Note2: Due to lack of program memory space in the STM32F401RCT6 SoC some features had to be disabled 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.

CV LASER MODULE SUPPORT for Ender-3S1!! https://github.com/mriscoc/Special_Configurations/releases/tag/CVLM laser-small

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. The firmware and its wiki are not really intended for beginners but as a supplement to already existing guides.

How to install the firmware

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 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. 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

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.

MPC has proven to be a better algorithm for keeping the nozzle temperature stable, and is also very useful for high power heaters.
