@oliof I did chat to Stewart about this at ERRF last year. it is very cool that Kiri:moto already has 4 axis for CNC
I also think that the term "slicer" is probably not how we want to think about using the combination of multi axis and non planar (like what Michael Wüthrich is doing with 90 degree overhangs by printing at an angle). "toolpath generation" is a bit long winded but more accurate. In some cases the approach of slicing in layers may be fine but in many cases layers are just not appropriate.
