It goes quite well. The printhead moves only on Y axis, all the way to the edge of the brim, wherever it may be. What i havent tried, is to put two objects, on different positions on Y axis, to see if the printhead moves to the absolute further position over the edge of the brim on Y axis, or if it is relative to the current X position and just goes to the actual edge of the brim (i dont know if that makes sense)
