I am in the same exact boat. I’ve had s3d I think since it’s inception. It was unpleasantly expensive but it was also just far better that the slap dash free sliders at the time (manual supports and a good preview were a game changer). But I’ve just been using it on momentum for the last few years.
New slices have interesting infills and organic tree ports and all sorts of fun feature. I was hoping s3d would step up so I wouldn’t have to recalibrate everything for a new slicer, but I think we’ve reached that point.
