Sticking on the build platform and the vat

I dont want to make too much assumptions here and leave the diagnosis to the experts.

Since approx. 1L of printed resin I have the problems shown in the pictures. 99% of the prints fail.

  1. Dents in the base

  2. Supports not touching the object.

  3. Wobbley supports or snapped supports.

  4. Failed Prints that miss out parts that stick to the vat.

It also seems that the resin is stickier than ususal after cleaning the models.
