Hello,
I am new to the 3D print community and have just put together my Ultimaker +, however sadly my prints do not work as I hoped. When I auto home the axis, the x and y components of the head go into the left front corner as supposed to and hit the end switch. After that the plate from the z-axis does the same thing, hits the end switch and is basically set in the right position, ready for printing. However, when I look at my UltiController, the coordinate reading says 0 for x and y, but -49.5 for z. When I hit print, the plate goes down to its relative zero point. This zero point is not 4
