Z-axis steps per unit

Hi everyone,

I got myself a trapezoidal z-axis for my printer.
After installing it, I changed the firmware-setting in configuraton.h to 2133.33.
Now when it check my z-axis, it still moves as with the old setting.

However, if I change the setting with M92 Z2133.33, it works

What have I forgotten? I don’t want to set this everytime I want to print something.
And yes, the Jprog was shortened and the LEDs were blinking
