Where to put the new Repetier-Host-Settings

I downloaded the newest version for my K8400 and uploaded it to the board…

but in the zip file there were Repetier-Host-Settings. Where do i have to put them in so that my Repetier Host can use the better settings?

Thanks for your help =) im new in this buisness

Greetings from Switzerland

What download are you referring to?

i found the updated version here-> http://www.k8xxx-3dprinters.crimed.be/w/index.php?title=Mod_extrud

This is an unofficial version correcting the usual over extrusion observed with the original one from Velleman.

The Repetier files must be loaded in the Cura setting folder :
Print folder : Import the FIX_SINGLE_HEAD.rcp file
Filament folder : Import the FIX_PLA.rcf file

thank you for your help =)
