What's New in this Release ‐ Ender‐3V2 Build
Continually updating with Marlin bugfix-2.1.x
Tip
You can use the Firmware Selector to help choose which file to download.
To update the firmware, choose the file ending in .bin and place it in your SD card:
(You may need to rename the file if reinstalling or if it doesn't flash the first time)- For a Creality board, put it in the root folder of the drive Or unless otherwise specified
please flash the new DWIN_SET now!
This is a universal firmware that has been optimized and enhanced for both the Voxelab Aquila and Creality Ender-3 V2/S1.
This is based on MriscoC's Professional Firmware for the Creality Ender-3 V2/S1. This particular build release is for the LCD color displays of Voxelab Aquila or similar variant. If you are using a Creality brand screen you can try the -TJC version, or the Ender-3V2 build here.
- BTT SKR Mini E3 V3 / V2 / V3.0.1 finally supported for ProUI - (4.3" Stock Aquila/Ender-3V2 Color LCD)
- If you have a TFT or other display, you can request firmware *.bin files to be made, or compile your own
- BIQU MicroProbe V2.0 is now supported with _BMP prefix
Important
🚩To use this version, you must✶ update the DWIN_SET to the LCD screen. New ICON's have been added, and others were remastered.
- Choose a DWIN_SET from the "display assets" folder
- Copy it to the root of an SD card
- Remove the name in ( ) from the folder e.g. "DWIN_SET (Original)" => "DWIN_SET"
- Open the back of the LCD, insert the card📲
- Turn on power, wait until the screen goes Blue🔵 to Red🔴
- Turn off, remove card⤵. Good to go!✅
✶ Technically you don't have to reflash the new DWIN_SET, but some ICON's will be missing if you do not.
Warning
While using _BLT or _MM versions, if you encounter the bed Mesh not saving... This workaround resolves the issue without having to redo the mesh again.
- Build Mesh (first time)
- Save Mesh
- After any time you Power Off and Power On --> 3a. Go to Control/Advanced Settings/Load Settings -OR- 3b. Load this into your Start Gcode
G28 ; Home M501 ; Load settings M420 S1 ; Pull your mesh bed level ;(Remaining Gcode / Start Print)>>>
If you experience this issue as it starts printing --> Mesh leveling data is drawing over the printing screen Go to Slicer Gcode Scripts
Note
⍰ The follow may apply to you if the mainboard chip supports 256KB max
Note ➀: Due to lack of flash memory space in the Aquila's GD32/N32|F103RCT6, some features had to be disabled in the ProUI of UBL and BLT versions, including, but not limited to:

Note ➁: The latest releases are promoting UBL versions over ABL (BLT - BL Touch), but ABL/BLT versions will be available. MPC autotune is available for the hot-end as a replacement to PID autotune.
- These are the configurations offered:
- [ _Default-NP ]: Use if you have a near stock machine Default No Probe
- [ _MM ]: Create a bed mesh without an auto bed probe Manual Mesh Bed Leveling
- [ _BLT ]: Use if you have a CR/3D/BL-Touch level sensor installed. Bilinear Auto Bed Leveling
- [ _UBL ]: Similar to both MM and BLT - with more options. Recommended over BLT Unified Bed Leveling

| Power-Loss Recovery | (Resumes where a print job left off when there is a power outage)
Prints will be effected regardless. May require a special breakout board or test prints to calibrate.

Binaries with UBL in their filename are similar to the bilinear leveling of BLT, but with extra features to provide users with more control and information. There are multiple guides about UBL, it's recommend reading about it before using this type of leveling system.
