Print times between Cura and Slic3r (in Repetier) 5x difference in Cura + plugins Posted June 23, 2015 I think I figured out a good portion of the issue. For some reason Cura doesn't acknowledge the 80mm/s infill. It appears to be closer to 20mm/s. So I am using Curaengine on Repetier host to slice the model and then saving the gcode out as Ulitigcode flavor. So the UM2 recognizes the code as cura driven and all of the built in firmware is intact. I get nice startup and finish sequences but I get better control of the speed during print. I'm back to being happy with my printer. I just don't understand why Cura wasn't working for me. Oh well, I'm happier with Repetier controls and part management anyway. So Win Win!
