Problems configuring Marlin

Hello,

I am running a Tevo Tornado. I changed the Hotened as well as the Z screw.
I downloaded the original Firmware from [github.com] .
Next I "configured" the original Firmware, mainly the kind of temp sensor due to the hotend change and the "DEFAULT_AXIS_STEPS_PER_UNIT" from the new screw.

The Hotend does work without any problems, right temperature etc. so the modified Firmware did upload. And the Arduino IDE didn't output any errors. (I am running Manjaro on my Notebook if that has any Influence, although I doubt this)

I do However have a Problem regarding my Z Screw.
I multiplied the existing value from "DEFAULT_AXIS_STEPS_PER_UNIT" (from original Firmware "400" ) by 4, to "1600", since the new screw has four times as many winding's. This However had no effect. I know this since the Distance traveled by the Z carriage was only a fourth of what it should be be. (25mm instead of 100mm) I even multiplied the modified value again by 4, and flashed that version, but still no effect. The other axis still move normally and accurately.
Unfortunately I am out of ideas.

Any help is appreciated, thank you in advance.

* Default Axis Steps Per Unit (steps/mm)
 * Override with M92
 *                                      X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
 */
#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80.3190, 80.3190, 399.2901, 400 }

Maybe you changed the steps for E0?

Thanks for your reply,

but I only changed the the third value.

Did you do M502 - M500 after flashing?

Thanks that did it. I am an Idiot.
