Just put together my pancake bot. Two comments. There seems to be no suction, or pressure from the air pump, either on 1, or 10. When I try and print a design, it just slowly drips, exactly the same if I didn't have the hose in at all. Are you supposed to be able to hear the pump? Also, is it possible I received a used unit? While most of the unit seemed new, the gantry section had what looked like dried pancake batter on it, and the ribbon cable had a whole section of residue where I assume a piece of velcro was supposed to be. I took pictures of both. Griddle works great though, We used the bottle and the hose and held it in our hands and used our breath to hand make some pancakes - while fun, I would like to fix it. I'm comfortable opening it up (I have built many 3d printers), but assume I will void the warranty if I do.
