Creating a custom Start screen is a great way to personalize your Voxelab Aquila by adding some flair at a very easy cost.

This process is usually done while updating your firmware. If you aren’t familiar with that process please check out my BL Touch and firmware video for instructions.

During the firmware update for our Display (yes it has it’s

own firmware) we have the option of choosing icon

themes. There’s a few to choose from, all labeled

DWIN_SET(Insert Theme Name). This customization is all

going to be done through that DWIN_SET folder. From the

Marlin source code. We need to:

  • navigate to display firmware (1)

  • then Firmware Sets (2)

  • finally we can choose one of the DWIN_SET folders (3)

  • Inside the DWIN_SET folder the first three files you see all start with a numbered prefix (0_ , 1_ , 2_ ). The first file "0_start" is what we want to change (4)

You’ll need to create a start-up screen that is 480 x 272

pixels(5). This can be done by something as easy as

editing in MS PAINT3D(6). First you want to make sure your

image has been rotated 90 degrees to the left(7). The

firmware will apply the image with the left side being the

top of the screen, and the right side as the bottom, so you

need to rotate your image according to that. Next simply

change the canvas size to 480x272 and have the program

scale your picture with the canvas - be sure ‘lock aspect

ratio’ and ‘resize image with canvas‘ are selected

before scaling(8) - When locking the aspect ratio your

image may not be exactly 480x272 pixels once scaled. This

is fine as long as the pixel size is at or under those

numbers. You can also choose to uncheck ‘lock aspect

ratio’ to get an exact 480x272 pixels but your image may

look distorted. Once it's been rotated and scaled save the

image somewhere on your computer as "0_start". It needs

to be named exactly as the first file in the DWIN_SET

folder. After you've saved your custom image, go into the

DWIN_SET folder and delete the original "0_start" image

(might be a smart idea to copy that image and store it

somewhere on your computer just in case), after you've

deleted "0_start" image it's time to move yours into the

folder(9). Just copy it from it's current location and paste

it into the DWIN_SET folder and viola! you're done! Just

finish updating your screen firmware as normal.

1.) Display firmware

3.) DWIN_SET folder of your choice

 

5.) Check your image’s starting Pixel size

 

7.) Make sure to rotate your image before performing any scaling

9.) The final step of inserting our custom start-up image into our DWIN_SET folder.

2.) Firmware Sets

4.) The ‘0_start’ file is our Startup screen, which we want to replace

 

6.) Choose Paint3D to edit your image

8) Both of these options need to be check in order for your image to scale properly. Make sure the sizing is set to ‘Pixels’
