Hi, i got a problem with two of my printers. I got 2 Daycom 3DP-100. They worked fine but then i decided to update them to Marlin 2.
Everything works fine, but i can only see the backlight of the LCD and no menu. Except i reset the printer. Then i can see the menu for about 1 sec. After this it vanished.
I searched a while with google and found out that i`m not the only one with this issue.
I got the original files from the printer and the marlin 2 files but i can`t figure out what`s wrong.
Hopefully someone have a clue. I tried #define DEFAULT_LCD_CONTRAST 17 in the conditionals_lcd.h but this didn`t change anything.
