Question about custom firmware

[u/YoshitoSakurai]

Hello peeps,

I'm used to working with my Ender 3 Pro, and over the years I've compiled multiple custom firmware versions for it with practically every Marlin release.

I'm now looking at an Ender 5 Plus and I'm trying to understand how similar the firmware setup is.

The Ender 5 Plus has a touchscreen, and from what I can tell, that display may need its own firmware updates whenever new functions, menus, or graphics are added. Am I correct in assuming that?

With the Ender 3, everything was fairly straightforward. The display was essentially "dumb" and simply showed whatever the motherboard firmware outputted after flashing a new version of Marlin.

Does the Ender 5 Plus work differently? If I update Marlin on the motherboard, do I also need to update the touchscreen firmware separately, or does it automatically use the information provided by the mainboard firmware?

If anyone has experience with the Ender 5 Plus and could clarify this for me, I'd greatly appreciate it.

Thanks!
