We can set bottom lift height and normal lift height indiviually.

because bottom layer stick strong at FEB film. 

So I set higer lift height for bottom. and i set less height for normal layer to save time.

but problem is when it changes from bottom layer to normal layer,

After last of bottom layer exposure, lift height is change normal layer height.

It means, Last bottom layer applyed normal lift height. so it causes printing problem.

Is someone knows how to fix it?
