FEP Sticking ...

As he said previous. If it a Mars Pro the build plate is a little slick. Use a scour pad. The idea is just to give the resin some texture to adhere to. After all the prints I have made now, this is definitely a good answer. You can use the green side of a scrubby sponge and that works too. I would not use steel wool or sand paper, as these are too harsh. And you want to get the surface to a satin finish.

I'm experiencing the exact same thing with my Mars 2 Pro. I've tried everything mentioned except leveling with 2 sheets of paper. Definitely going to give that a try tomorrow.

EDIT:
Leveling with two sheets did the trick!
