Working out some calibration issues on my Rostock Max and ran into a couple odd things in KISS. I created a simple test object consisting of two cylinders, each with a wall thickness of .55mm. When I slice it in KISS I end up with gaps in the final object. I've also had KISS tell me that it can't slice the object as the wall is thinner than the extruded width and it just quits. The picture below shows the preview in Repetier.
So, I made a second opbject with 1.1mm walls which KISS sliced fine. When I printed it with my typical settings for ABS (prime 10, suck 10, wipe 5) it looked like it was starved for filament. I changed to prime 6, suck 6, and wipe 3 and the print was very nice. Now I'm wondering how many issues I have been chasing are actually caused by the slicer and not delta arm blues...
I'm curious if anyone has seen similar issues and what you did to correct them? Any killer tips on KISS?

The "right" way to do what you want is to make a model that is a solid cylinder, set Kiss to VASE mode i.e. 0% infill and no top, set perimeters to 1 and set the wall thickness to your extrusion width.

The problem with doing what you are doing is that the odds are when you converted the cylinders to polygons some of them are very slightly narrower than the extrusion width, which results in what you are seeing.

Thanks polygonhell, worked like a charm. The 3D modeling side is new to me. I assumed that the conversion to STL would be reasonable accurate. Any other tips like that?
