roughcal part for determining the X/Y offsets

use .25mm layer height.
you will get two layers for the base and 1 layer for the lines.
assign 1 extruder to the base with it's lines. (purple in this case)
assign the other extruder to the individual lines. (green)
use 0,0 for offsets initially and look at the lines after printing.
make sure to use a prime pillar or other way to ready the incoming extruder.
I've included Kisslicer INI files for X-Truder users.
