Hi ! I'm new with SLA printers and i have the same problem with AnyCubic Eco White Resin when I made a calibration test. It forms a kind of residue around the edges not just the first's layers like this. Any ideas how to solve this ?
I use setting:

-1.7s exposure time per layer
-50mm/m lift
-120mm/m retract
-0.25s Light-Off Delay
-70% UV
