Yes, I know about manual support and I'm mostly using 0.7, 1, 1 settings for layer separation, but sometimes (i.e. to prevent ABS warping) I need to set layer separation to 0. And sometimes supports are melted with main material within one layer. Also (but I need some free time to check this more carefully) I found that models printed in ABS with honeycomb are more resistant to warping (all other settings were similar).
If anyone interested I spent sometime printing extruder for prusa i3 with slic3r (with honeycombs) and creator and, unfortunately, creator's extruder is U-bended
In support they reassured me that they are working on new infills, including some mystical _improved_ honeycomb
Hope to see my favorite slicer with my favorite infill very soon!
