I use hair spray on my bed and something I am wondering is how can ABL work with that? I would think that the ABL would just sit on top and the spray may be low in spots and adjust down to that level so simply doing a Z compensation would be a very bad thing as it would scrap into the glass in spot and in others would be what I need.
How do people work with this since we want the print to go into the spray but not through the glass?
