Here are som sreen issiues , that i found using my LCD graphics display (see foto's).

One of the things that by me occured , by using the LCD is , letters "..mm" above the others .

Changing the hight from caracters will do the trick ?
And the sound of the beeper by clicking , can i dim this and how ?

My LCD display is a HE3D from Aliexpress

Is there sombody who nows the answer ?

It looks like your display is overlapping the characters "mm:" and "+00", trying to display 17 characters in the space of 14. Hard to help further without knowing what you're using to drive the display (Arduino, etc.) and a sample of the programming.

My motherboard is a Melzi 2.0 board (Atmega 1284 16mHz) with Marlin _1 firmware and U8glib for driving the LCD .

Is there perhaps a config setting problem ?

I have contacted Oliver Kraus the author of the U8glib , an text me that this is not his problem , his software works fine.

Perhaps a Marlin problem ?

I have the same issue, also using 128x64. My setup: RAMPS1.4 with Arduino and Marlin Software + U8glib

Hereby the foto from the problems on the screen .

Is this the same thing by jour screen , a screen type issue perhaps?

Have looking in the "doglib.cc" file but i can not found any faulty caracter setting or templates .
I am not a C++ specialist , have some degree of programming expierience with "dbase"programming " but C++ is not my piece of cake.

Let's hope , perhaps is there some one with a proper solution , but this is not a mayor problem for using the LCD now.

Yap, exactly the same. I didn't consider this as a problem, because I still can read what is meant, but I thought this is the case for everyone.
So, if there is a fix, I would gladly apply it. Although I would not really invest time in finding it on my own, because my other printer related
problems are much more pressing ^^

Check the settings in dogm_lcd_implementation.h...

#define USE_BIG_EDIT_FONT                // save 3120 bytes of PROGMEM by commenting out this line
#define FONT_STATUSMENU u8g_font_6x9
#define FONT_MENU u8g_font_6x10_marlin

// DOGM parameters (size in pixels)
#define DOG_CHAR_WIDTH         6
#define DOG_CHAR_HEIGHT        12
#ifdef USE_BIG_EDIT_FONT
  #define FONT_MENU_EDIT u8g_font_9x18
  #define DOG_CHAR_WIDTH_EDIT  9
  #define DOG_CHAR_HEIGHT_EDIT 18
  #define LCD_WIDTH_EDIT       14
#else
  #define FONT_MENU_EDIT u8g_font_6x10_marlin
  #define DOG_CHAR_WIDTH_EDIT  6
  #define DOG_CHAR_HEIGHT_EDIT 12
  #define LCD_WIDTH_EDIT       22
#endif

  #define DOG_CHAR_WIDTH_EDIT  6
  #define DOG_CHAR_HEIGHT_EDIT 12
  #define LCD_WIDTH_EDIT       22
#endif

I think I have another version of this then. My file only says:

// DOGM parameters (size in pixels)
#define DOG_CHAR_WIDTH         6
#define DOG_CHAR_HEIGHT        12
#define DOG_CHAR_WIDTH_LARGE   9
#define DOG_CHAR_HEIGHT_LARGE  18

#define START_ROW              0

Your settings are right there... Try changing the following lines:

#define DOG_CHAR_WIDTH_LARGE   9
#define DOG_CHAR_HEIGHT_LARGE  18

to

#define DOG_CHAR_WIDTH_LARGE   6
#define DOG_CHAR_HEIGHT_LARGE  12

Note the 2:1 height to width ratio. 8 and 16, 7 and 14, etc. should work as well.

My file is the same version of you.

I have tried with this numbers that you sugested and notting will changed it is still the same overshoot therefor i have changed my text in the language.h module
from Xsteps/mm to Xst/mm and this is working well , i can read the numbers again.

In the language .h module can you change the language and the name of your machine , thats displayed op the first page from the LCD , if you want to .

There are also 11 languages available myn is number 11 (Dutch)
