Recently I changed the FEP bottom of my Anycubic Photon S and I'm having problems with prints now. The bottom layer sticks super well, but none of the supports or the prints do.

I've tried tensioning the vat, releveling, and changed supports of the structure. Nothing works and I don't know how to proceed.

I also tried tightening all of the screws on the build plate, but still errors.

I'm using Anycubic black resin, 8 bottom layers at 90 seconds, 7 second exposure with 2 seconds off.

The image shows a failed print example:

I finally reached out to anycubic and their tech support answered and was awesome!

They had me update the firmware, tighten the fep film more ( instead of using the small lever I used the big lever this time), then level the bed again. I printed their test print and it worked!

After that I looked at their parameters and I saw that mine were very different. The main differences was in the lift distance, speed and retract speed. I only had 1 mm lift distance and much slower.

Here are the correct ones in the end

true parameters
