Thanks for answering. So far i failed most of my bigger prints because of total clogging, or just finding the machine "printing in the air" or, less likely, the wire spool getting stuck somehow. While i can address the last problem quite easily, i am getting frustrated by the first two events and really don't know what to do. I think i could never print successfully for more than 12 hours. I don't know if this is normal. It's very easy for me to go past that printing time when trying to print objects of moderate size and details (i mean something of about the size of a 500cc can of Coke). I wonder if there's a problem, or i am doing something wrong, or if it's just my expectations to be unrealistic. But how can i use so much space of Ultimaker 2 Extended then? I have a couple of questions to understand if i can get what i would like to:
1) what's ur longest print time? What material were u using?
2) is it possible to print, for example, a 1:1 size human skull, or a puppet as tall as the whole space, all in one go without expecting printing failures?
