So this is the +1.5 sec exposure from Siraya techs default settings for elegoo saturn ultra 3 showing as a size 6.5 instead of 7. And the -1.5 sec exposure not showing much better. What the middle pictures show are the fact that the +1.5 second one is showing that one side is thinner than the other. This would be the angle my sprue tree has the rings at, so now im going to repeat this test right side up as Matrix Gold defaults it and see if it makes a difference. Yay to another 5+ hours of printing. Good thing no one is fighting me for use of the saturn ultra 3 @asmblyaustin in the time booking program right now 🙃

After deep thought, the low exposure setting that should result in the size accurate continuing to fail with multiple prints, and considerations for casting shrinkage anyways, I am instead going to aim for consistently a half size off because if I can do that, it is a simple matter adjusting the ringsize in matrix and saving the exposure settings.
Now im going to see if the neighbors shoot a firework through my window while setting up my next print test.....
