My demo ran put but before it did I put Creator 3d through some tests and was liking it, but then ran into a weird problem.
See attached photo
Left= Creator 3d, middle= Slic3r, right= KISSlicer
I have some real backlash type problems with Creater 3d when compared to the other two slicers. The other parts for this model where not as bad, in fact they where clean except where the hole was for the joining part, Creator 3d had backlash type problems while the other two where clean.
