I notice a radical effect of the resin left in the tank after a print. If i fill the tank up, print, the parts are perfect. I do notice that the resin left is thicker, presumming partly cured. If i run a second print, the finish is reduced dramatically. I beleive the thicker resin, sticks more to the part, and being partly cured is finally cured from the uv radiation on a new layer.
Would it be possible to have a more detailed scale (vernier) for the volume of resin? This way we could put 50ml for a 25 ml print for example or even a bit more to compensate with the resin that sticks to the part.
