>So why is Cura the software coming up with print times 3X as Curaengine in Repetier?
About a year ago the print times that Cura claimed were way off. It would typically print much slower - especially if there were many short moves because the printer has to slow down on each corner - each vertex. Cura fixed this about a year ago and now has pretty accurate print times. I don't think slicer does this. So the print time out of slic3r may be innacurate.
Anyway, I suggest you try a large cube which has lots of long straight lines and maybe try 50mm/sec. Try doing only single pass shell width (.4 and .5mm) make sure layer height is the same, turn off infill for both, turn off top and bottom. See what you get then turn things back on one at a time to see what's different. There's other things like "min layer time" that can really slow down a small part but doesn't affect a large part (say 100mm cube).
Ok, just for giggles I set Curaengine to be the slicer in Repetier and got similar results to Slic3r in Repetier.
So why is Cura the software coming up with print times 3X as Curaengine in Repetier?
