K1C Linear rail brush mod

Did the linear rail mod on my K1C, but found out that my toolhead did not reach the brush corectly. 

Change clr_noz_start_y: 219 for the new brush location.

Uses stock brush from the plate, heat it up and pull it off. Install with stock screws near the back Z-rod.

Print with ABS or better. Don't mind the cables, ill fix them…
