Primeline different in RatOS 2.0 than in 1.x

Hello Guys. Can someone Tell me how i get the old Position of the Primeline from RatOS 1.x back?
In RatOS 2.0 the Prime Line is on the opposite Site (right) now. And the gantry slams a little Bit to hard into the Front right Pully Plate.

I own a V-core 3 400
