Yep, you’ll never get it perfect, but a smaller layer height will make the steps less noticeable. Adaptive layer height in cura if you use that can help, but adds a mortal age to the length of the print.

It’s probably under exposed then. Something like this and this will help you tune your slicer settings. You might need to play with other settings if you have other issues, but most of the time the exposure settings will be the problem with new resins.

Is this the first print you’ve done with it? Have you done any exposure calibration with this resin?

Ethanol should be fine to use as far as I know. Do the holes go all the way through? If so your screen might have dead spots. You can visually inspect the screen by setting it to do a test exposure without the resin tank on it to check. Also obviously check that your tank doesn’t have any failed print bits stick to the sheet.

The industry is experiencing historic shrinkage post COVID due to unsustainable growth during COVID.

It’s not an easy transition. My partner works for DDG and I still don’t use it all the time. To their credit they are working to improve things but it’s a small team (comparatively). Their browser has some good features like app tracking protection just from having it installed and quick throwaway email support but isn’t quite up to Firefox’s standard (yet).

Less competition for their farmers/Shortages mean higher grain prices.
