I built Cupcake #235 and in my first few prints discovered it required maintenance, adjusting, tweaking, etc, to make a good print. My Cupcake is old enough it has the CNC skin instead of the Cupcake skin so it really is a pre-alpha product. Instead of leaving the tools on the desk next to the Cupcake I designed some interchangeable mounting brackets, plans are on Thingiverse.
