First of all, I´m quite happy with the new version 3.0 at all, I like the new features, infill options and so on.
BUT there are 2 problems I´ve noticed:
1. The software got very unstable. It crashes very often during the slicing process, during the preview loading or when I´m loading old G-Codes. That happens randomly and not repeatable at a specific file.
2. The model repair has become worse. Many parts i was able to slice with v2.2 now have defects with 3.0, even if NETFABB says that the part is watertight.
Sometimes I can solve the problem by changing the parts position by Z +-0,01.
Because of these problems, I needed to switch to the older verssion 2.2 to slice some parts correctly.
Booth are serious problems which need to be solved as soon as possible.
