Yes... some of the jewelry that we make is pretty big , more surface area ,rounded shapes, stone settings etc... like bracelets.
And then we support Jewelry stores in our area, so thats why 2 B9's. right now, I have around 45 models that I need to print for designers.
On some items I have printed at 30... The ring I am talking about, I tried it at 30 quite a few times using stock settings and a low MSM number. The thickness went from 1.1 to 1mm when the file is .7mm. In platinum, thats a difference that you don't want to grind off! On that ring, I ended up sanding down the B9 cherry components to the correct size after curing and got the ring out... I think I printed over 25 of them and did not get where i needed. I have one on the machine now with my lowered projector just to see if it helped. I am missing some setting. I don't blame the machine... I just have not been able to figure out how to make items thinner on the machine. ... Yet :-)
