Used S3D since v3.x then v4.x and now v5.x.
In the old days there was nothing that could do what S3D could do, but times have changed!
S3D is so far behind the free ones (Prusa, Orca, Cura, etc.)
I have asked for technical documentation in the past and now, and still nothing beyond this forum?
I have asked for documentation on macros, and each time I get a short answer in the forum with a solution, but still no documentation?
I have reported several bugs in v4 which have been fixed, and in v5 which are still not fixed?
I have recommended quite a few improvements and nothing has changed?
I follow the forum, mostly to see if anything changes, but everything is the same, which is bad.
I have so many stl files that I myself have drawn in F360 and sliced in S3D. They are all re-sliced in Prusa, with a super result.
I don't think S3D can keep up with the free ones anymore, and those who still pay should consider spending the money on a better printer or something else.
If I were to start over today, I would never choose S3D, because there are so many other free options, with great support and documentation.
Just gotta say I'm disappointed.
