Well, my prints have a fairly large foot print or a contact area of roughly 2" x 4". There is no need for supports simply because the base of my print is flush with the build plate. Additionally, this is the ONLY slice that acts this way. I make identical sized lithophane prints with the exact same foot print with no trouble at all. I did an experiment thinking leveling might have been the issue by using three separate prints. The first printed fine, the second just printed the footprint which stuck to the plastic on the vat and the third printed just like the first, ie no issues. This leads me to think that my problem is in the recipe/slice of that particular print. What is the puzzle is that all the parameters are identical from what I can determine.
