geared : cura vs slic3r

i was trying to print this small gear in slic3r and used a lot of different settings and kept getting gaps..... Just for trying i used cura to slice the gear using exactly the same setting as slic3r .... vola much better print...

the one in cura is on the left and the one on the right is done in slic3r 0.9.10b.

layer : 0.25
nozzle 0.4
abs white
perimeter 2
infill 50%

same with me...tried few days ago same thing, with slicer and 100% infill the results were same, but with cura no problems.


generally, i find cura slicer much better then slic3r


also it works faster with less moving, better in every term..

but i cant connect cura to repetier firmware, so i just export gcode to repetier host...
