I try simplify3d to a my costumer and I have to say is very incredibile, more then cura
I wanna buy it but I see an orribile defect when I have a surf c'è in the middle of one parts.
If I have a top layer but the print have to made olso perimetro for continue the costruction simplify3d make top layer first and after the perimeter
But if I have a no good infill the top layer don't result very good, if I made first the perimeter maybe the top layer extrusion will fusing with the perimeter
I have a lot of part I will have this issue, Cura don't make this...but for the rest its a very good software compliment
