I’ve had my MK2S printer sitting in a box for quite some time (I did have an X-carve to put together and a few assignments to grade – oh and I published a paper, but more on that later).  This is my second 3D printer, the first being a Makerfarm i3v.  I love my first printer, and it taught me a lot about the design and maintenance of these machines.  That said, I’ve always had a hard time with calibration and getting the prints just right.  My first successful 3D print with the i3v was a cube in ABS, and I was so proud.  Here’s my first successful print with the MK2S (brought to you from one of my students, Anusha Ventress, who is moonlighting as a videographer while she works in my lab):

OK, technically, this was the 3rd successful print on my MK2S, but all I can say is: wow.
