I started resin printing a couple months ago. I had some of those layer problems too. I found that I need way more supports than I thought I needed at the beginning. This is a pretty good guide on supoorts. Alternately Ive been using lychee slicer’s auto supports. They seem to work well for the most part.
I also just recently did some exposure tests. It takes a while because each test is about 20 minutes but it turns out I was under exposing my prints so things are better now.
Lastly I replaced the usb stick the printer came with. I highly recommend doing this right away, a bad stick can do weird things. I got two 64gb Kingston data travellers for $10 Canadian. It’s well worth it.
Haven’t had the layer issues since I did these things and, fingers crossed, I haven't had a failed print since either.
Any time!
If it didn’t print at all I’d be looking at that USB right away. I had many half printed things and corrupted files before I clued in.
