I just tried the Photonsters Validation Matrix V2 on my new Saturn 4 Ultra 16K and was running the exposure test with 8 models. I had three of them pull off and stick to the FEP (after emptying the vat and filtering the resin). I started with the profile for the printer in Chitubox so the bottom layers are 4 (per the instructions on the model) and the bottom exposure is 32s. Should I increase the bottom exposure and if so by how much? This was my first resin print so I'm not sure.
