When we calibrate the Ultimaker, we use the function to feed material and then manually move the head along the X- and Y-Axes to verify that the distance between baseplate and printer head is good. It would be nice to have a menu function which automatically does the following:
On first invocation, it draws a rectangle on the full size. Then, we can make adjustments to the baseplate, and invoke the menu item again - which draws the rectangle, but with a small offset from the outer boundaries. On each invokation, the rectangle would become smaller, until we finally have the baseplate adjustment which works well.
