I thought I would share a bit of a trick I've been using for a while now about not limiting yourself to the default gantry height.
For those not aware of what the gantry height is, it's the clearance you have between the bed and the lower axis metal rod driving the print head movement. This is what limit you when doing "Print One At A Time" prints.
Something I have come to like about Cura is to be able to change settings even for a very well defined printer like the UM2. Cura
