Enhancement #1539
Description
Did you test with a precompiled firmware?
Yes, and the problem still exists.
Bug Description
Hi,
while customizing the German language file and testing on a TJC/DWIN setup, I ran into a few structural issues:
LCD_LANGUAGE was being undefined in Conditionals-2-LCD.h unless specific UI flags were set.
Some Preheat macros (PREHEAT_2/3/4) are not consistently exposed via _msg_preheat(N) which leads to missing translations.
Several UI elements in dwin.cpp are hardcoded in English and bypass the language system.
I prepared a cleaned and merged language_de.h including missing identifiers from language_en.h, removed duplicates, and verified successful compilation.
Additionally, I tested a small modification replacing hardcoded strings in DWIN with GET_TEXT() which worked correctly.
Would you be open to:
including the completed German translation?
exposing missing DWIN strings to the language system?
I can provide the cleaned file and patch if useful. (attached)
