I have never sad that my tower or the prints came up from the plate. The pva do not stick on the interface layer.
As I know dryness is key, I handle pva with care.
I made hundreds of prints with pva for support material for my prints and in the past it works perfectly. I bought the h2d to decrease the printing time significantly due to the dual nozzles and the resulting reduced changing time.
Unfortunately I have to go back to my p1S for this kind of prints.
