If you're having difficulty getting your prints to adhere to the platform, you might need to add texture to its surface using 100-200 grit sandpaper.
To do this, you'll need: 100-200 grit sandpaper, Isopropyl Alcohol > 90%, Paper Towels, Gloves
Starting with a clean, resin-free platform, sand the surface using light circular motions. The idea here is to give the platform texture, not to polish it.
Before using your newly roughened print bed, you'll want to clean its surface with a paper towel and Isopropyl Alcohol > 90% to ensure that no metal shavings will contaminate your resin.
