Over the past 4 months, I've been able to get quite dialed in using our Solus here in the shop. I am admittedly very new to jewelry-making as well as to resin printing, so there's been quite a learning curve. That said, I've scoured this forum and haven't been able to solve a few mysteries. The first is the presence of some lines in both the Z axis and in some other axes.
In these two photos, hopefully you can see the lines that appear vertical on the ring. Toward the top, they appear to curve over the edge. (I'll kindly ask that you ignore the various casting issues for now, as that is another, extant issue we're working the kinks out on and I'd love to just focus on one problem at a time

In these photos are a print of the exact same model in the exact same orientation with the exact same settings. This is post-curing (several hours in a distilled water bath in a box of 2x20W 405nm UV lamps.The lines are present here, as well, so it seems not to be an issue with the casting. You can also see some horizontal lines, which are also an issue I'd like to solve if the two types are unrelated.
The next photo is the same model printed at a smaller size (to save on resin) and oriented at a 45 degree angle from the print bed. One is printed at 42xy, the other 25xy. Both were printed on a brand new film. As you can see, the lines persist at a different angle - though there appears to be some vaguely sinusoidal pattern to it.
I've done a handful more tests and a lot more tinkering, but I'm eager to see if anyone has any ideas about the fix or other things I could test to start figuring this out.
Some other data: projector hours are <300, I've tried this with different film tensions, I've fairly recently recalibrated the build plate.
Thanks a ton for any help or ideas!
