the utter enjoyment of watching a 3D printer actually printing…
up un down with the Z-axis?
oh yeah, it’s a beautiful thing 
it elevates the extruder when it moves to the next piece so it doesn’t knock into the surrounding pieces
What are all of the little white specks?
hahaha, i could pontificate on that but i don’t wanna jinx my machine 
I was wondering about them myself.
