Hello, we just picked up the UM2 and we ran into a few problems with the support structures. After a few hours the support structures would become inconsistent an not aligned correctly, almost as if it was melting. We are using White PLA, 220C 30mm/s. This seems to be a reoccuring theme for any projects over 6 hours. Anyone have any ideas why this is occurring? And also what is the typical maximum length the UM2 can print?
