marlin 1.03dev and LCD2004 problems

Hi guys,
I´m building a delta printer with above mentioned marlin version and Mega/Ramps combo. I´m using a RepRap discount LCD2004.

I found a weird behavior in the "move axis" section:
1. Although I´ve set XYZ speeds and acceleration to the same level, the movement with "move axis" is much slower for z-axis than for x or y moves.
Where can I change this?

2. When I move z-axis with pronterface/g-code commands it works perfect. Scale and speed are what I expect.
But using "move axis" leads to wrong scaled moves ( 50mm move turns out to be ~40mm )

Why does the LCD move axis code ignore my steps/mm and feedrate settings?
Where can I change it?

Thanks
-Olaf

Yesterday I also changed this line in ultralcd.h:

#define LCD_UPDATE_INTERVAL 200  //  100

But I´m not sure, if it had the desired effect.
I wanted to reduce cpu load by lowering the refresh rate of the LCD.
It seems, I can print at 200 segments per second now, without stuttering steppers, but I also reduced acceleration to 1600 mm/s^2

Can anyone put a clear meaning to the line of code above?
Is it in milliseconds or letters/ second?
A lower number means ...?

The LCD_move_axis problem still exists. Any ideas, tips?

My LCD ignores my Esteps/mm changes. I must use Configuration.h

Yes, I´ve read it already in two other threads you started about this problem.
My advice:
Start an issue in the appropriate github forum ( depends on your firmware branch ) like I did and you´ll find the answer.
Maybe it´s a bug or you need to define/undefine something in your config file.
