Easter break, so no progress on Slic3r, but happy to try Kisslicer or Cura.
Coming to the conclusion that the SW with the Cube is archaic, arcane and a pain when you want any refinements.
Anyway, thought I'd stress test the Cube and see what would happen when given an organic design to print.
So, in a fit of universal optimism, I loaded http://www.thingiverse.com/thing:1210985
(Hunters Skull), used a raft, no supports and let it go. Estimated print time 8 hours 45mins. So far 2 hours in and it's looking good.
A few random strings but other than that no apparent hassles considering the complexity and some interesting bridges and air gaps to contend with. Also printing without the extruder cover, results, at least in my office, appear better.
Will likely switch extruder sometime soon as well.
Guess I see the Cube as a "Build it again Project" for the Australian winter weekends while using the CTC dual for more serious objects.
