⍟ Firmware Selector ⍟

Tip

You can use the Firmware Selector to help choose which file to download.

How to install the firmware

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}

If you have not yet updated your LCD since: 2024-December,

please flash the new DWIN_SET now!

---

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.

1. Choose a DWIN_SET from the "display assets" folder
2. Copy it to the root of an SD card
3. Remove the name in ( ) from the folder
   ^{e.g. "DWIN_SET (Original)" => "DWIN_SET"}
4. Open the back of the LCD, insert the card📲
5. Turn on power, wait until the screen goes Blue🔵 to Red🔴
6. 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

🚧Please be aware of the following:

⚠️Previous Gcode Preview Thumbnails Issue has been FIXED! Thank you @Nazar78 for your help.

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.

1. Build Mesh (first time)
2. Save Mesh
3. 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
The correct way of set the start G-code script is detailed in: Slicer Gcode Scripts
Otherwise I would advice just not using G29 to build a mesh in the Gcode, but instead manually make one before printing, or just make one mesh for all prints.

Warning

🚧Please be aware of the following:

⚠️Previous Issue of it restarting when saving/store settings has been fixed. HOWEVER, now there is a current Issue to be addressed:
The screen freezes and restarts when SD card is inserted. This means that everything so far seems to work correctly as it should, except for when an SD card is inserted, so printing may not be possible unless you use USB serial interface to upload the file (through a slicer or something like Pronterface).

• MPC is enabled in firmware files containing "-MPC"
  Model Predictive Temperature Control
MPC has proven to be a better algorithm for keeping the nozzle temperature stable, and is also very useful for high power heaters. It does take some getting used to how it works if you are unfamiliar with it. It's recommended for advanced users, so stick to the default PID versions, especially if your printer is relatively stock

HC32 for November Rev.1

NOVEMBER 2025 REV.1

Version: 2.1.3g-11-HC32-1

Continually updating with Marlin bugfix-2.1.x

_{⬂ List of recent updates ⬃}

^{What's new in this release}

⍟ Firmware Selector ⍟

Tip

You can use the Firmware Selector to help choose which file to download.

How to install the firmware

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 an Aquila board, put it inside a folder named "firmware"
• For a Creality board, put it in the root folder of the drive
  ^{Or unless otherwise specified}

If you have not yet updated your LCD since: 2024-December,

please flash the new DWIN_SET now!

---

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.

1. Choose a DWIN_SET from the "display assets" folder
2. Copy it to the root of an SD card
3. Remove the name in ( ) from the folder
   ^{e.g. "DWIN_SET (Original)" => "DWIN_SET"}
4. Open the back of the LCD, insert the card📲
5. Turn on power, wait until the screen goes Blue🔵 to Red🔴
6. 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

🚧Please be aware of the following:

⚠️Previous Issue of it restarting when saving/store settings has been fixed. HOWEVER, now there is a current Issue to be addressed:
The screen freezes and restarts when SD card is inserted. This means that everything so far seems to work correctly as it should, except for when an SD card is inserted, so printing may not be possible unless you use USB serial interface to upload the file (through a slicer or something like Pronterface).

⚠️Previous Gcode Preview Thumbnails Issue has been FIXED! Thank you @Nazar78 for your help.

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.

1. Build Mesh (first time)
2. Save Mesh
3. 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
The correct way of set the start G-code script is detailed in: Slicer Gcode Scripts
Otherwise I would advice just not using G29 to build a mesh in the Gcode, but instead manually make one before printing, or just make one mesh for all prints.

• MPC is enabled in firmware files containing "-MPC"
  Model Predictive Temperature Control
MPC has proven to be a better algorithm for keeping the nozzle temperature stable, and is also very useful for high power heaters. It does take some getting used to how it works if you are unfamiliar with it. It's recommended for advanced users, so stick to the default PID versions, especially if your printer is relatively stock

⚠️Previous Issue of it restarting when saving/store settings has been fixed. HOWEVER, now there is a current Issue to be addressed:
The screen freezes and restarts when SD card is inserted. This means that everything so far seems to work correctly as it should, except for when an SD card is inserted, so printing may not be possible unless you use USB serial interface to upload the file (through a slicer or something like Pronterface).

⚠️Previous Gcode Preview Thumbnails Issue has been FIXED! Thank you @Nazar78 for your help.

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.

1. Build Mesh (first time)
2. Save Mesh
3. 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
The correct way of set the start G-code script is detailed in: Slicer Gcode Scripts
Otherwise I would advice just not using G29 to build a mesh in the Gcode, but instead manually make one before printing, or just make one mesh for all prints.
