Raft with top layers only

[kebes22 0]

I am trying to switch back to Cura after using Simplify3D for years. So far it seems to be much more powerful than I remember. One thing I can't figure out how to do though is disable the base and middle layers of a raft, so it will only print top layers. I do this regularly in Simplify3D for prints out of Carbon Fiber Nylon filaments. This is partly for adhesion, but also for more consistent surface finish of the bottom of the part. Having only a thin (2 top layer) raft allows super easy removal of the raft. If I print with base/middle layers, then it makes it much stiffer, and harder to remove.

 

Is there a way to disable the base/middle layers of the raft? Currently if I set the thickness to 0 it just fails on slicing. I have tried setting other parameters of them to zero as well, also with no luck.

 

This is almost a deal breaker for me, because it adds a lot of print time and material usage (and CF-Nylon filament is expensive). If this is not currently possible, then is there somewhere to make this an official feature request?

 

Thanks!
