Bad print, HELP!

I have cleaned the optical window (inside and out) Cleaned the mirror and new resin tank yet all my print have these deep ridges and the corner supports are not curing properly peeling away from the platform. and suggestions would be appreciated.

Hi, are you printing directly on the build platform?

Yes I am. I was at the AAO where they were demonstrating the new updates new function that only added minimal prints for direct platform builds. After seeing your comment I am now running one with supports. Stay tuned…

The reason I’m asking is because those ridges look like typical “suction cup” artifacts to me (but it could be some completely different reason, of course).
