DeltaWASP 60×100 printing problems

[AutoWiz]

So then they sent you the whole extruder? I am lost on the level of damage your printer took. When you say 'overheating' did you mean things melted? And is the new assembly of a redesign or is there anything different on it to give you the idea this will not happen on the next large print? And do you have any pictures of your 'overheated' extruder assembly to share with with the group? It's just to see something fail and put it back together the exact same way is a capitol waste of the most important resource our lives will ever know. Time. Did we find out why or do something to change the outcome we will get moving forward? And what on earth were the 2 previous failures of such an expensive machine?
