The mind of a slicer

[gajtguy]

Just curious as to why a slicer (Cura 15.02.1) would triple the same model, but slice it differently?? My drawer gusset has a chamfered bottom to slip over the top of a bullnose drawer side. So there is a little bridge to create. On three of the four parts it runs across the gap. But I've noticed it may also go across on an angle. Once it was trying to go parallel with the long side, which was not affective at all. This print was with ABS, @90bed, 220tip, .5mm, 35mm/s print speed

Part 2 of my question is: are there some tricks you use to get a better "grab" on each side of the bridge? I'd prefer some sort of overlap setting that could be increased so that the start position doesn't slip off. Any advise is appreciated.

I seem to get better results importing same model multiple times vs. letting the slicer create multiple copies.
In theory you would think it should produce same results, but that does not seem to be the case.

Sometimes shifting models around on build plate can produce different slice results.

I have had times when changing the layer height just a tiny amount will get better gcode.

Rotating part on build plate can change the slice also. In particular going "odd" amounts like 47 degrees or something other than 45, 90, 180, etc.

Or some models may get better results from a different slicing software.
