When I first tried to use the program I had a lot of issues. I complained quite vehemently about the software. Well after sticking with it and spending some time with the folks on the Duplicator 4 forum I have become not only a supporter of the program, but quite an expert user. I thought I owed the folks at S3D this after my initial rants. Don't get me wrong here, the program is not for the faint of heart, but if you are willing to put in some time and experimenting I think, like me, you will come out the other end loving this program. Especially the slicer. All of the options are overwhelming at first, but just plain fun after you master them. I am really printing some nice stuff these days and having a lot of fun. Thanks!
