How to Remove the Marlin Boot Screen and Extend Custom Boot Screen Display?

  • 0
  • 0

Hi everyone! 👋

I’ve successfully added a custom boot screen to Marlin by placing _Bootscreen.h in the project root folder, and it works fine… sort of. Here’s the issue:

  • My custom boot screen appears briefly, then it disappears, and the default Marlin boot screen shows up and stays for a longer time.

🛠️ Here’s what I’ve tried so far:

  1. I looked into the source code and found the void lcd_bootscreen function in the ultralcd_impl_HD44780.h header.
  2. Based on the comments in the code, I believe this function loads the Marlin boot screen.
  3. I added a return; to the first line of this function, hoping it would skip the default boot screen, but no luck—Marlin’s boot screen still loads.

My goals:

  1. Completely remove the Marlin boot screen.
  2. Make my custom boot screen display for a longer duration.

For reference, I’m using Marlin version 1.1.8. Any guidance or tips on how to achieve this would be greatly appreciated! 🙏

      To remove the Marlin boot screen and extend your custom boot screen display, modify the `lcd_bootscreen()` function in `ultralcd_impl_HD44780.h`. Instead of just adding `return;`, ensure your boot screen logic is set correctly. Look for code handling the duration of the display; you might find a delay function you can adjust. Additionally, check for any conditional statements triggering the default screen. Compile and test until you see the desired results! 😊
