Many software like cure or prusa slicer have become better lately. In my opinion there are several problems.
1) supports: there should be the possibility of inserting different models of tree type supports and also the automatic recognition is not as optimal as that of care
2) the possibility of being able to choose more infill models than those that are now would be welcome
3) On care there is an important function such as ironing for surfaces with better quality. It would be useful to implement it
4) heavy problem on printing time. It is not possible to print a model with forecast 15 h and then it ends after 24 h.
