Thanks RC, for posting that. For that reason, I don't like ideamaker , and to note S3D has the same issue. (I have to create a forum post over there on S3D to discuss ). I moved to Cura 3.0 and I am very happy. My latest print came out better than the S3D version.

So for now, Cura for me. (the UI is not so bad that you cannot get use to it )
