Model wraps when printed on top of a supports

[olegeng 0]

Hello 

I wanted to print something but it went wrong. In order to troubleshoot this I delete irrelevant part of the model and remain only the problematic part. This part must be printed in that orientaion. For some reason I get the first layer on top of the supports wraped. I tried to play with parameters but no success. Any ideas what causing this and how to solve that? 

Note about the model, this "wing is thin, about 0.6mm so it will not be too much layers there. the defect will be seen at any angle.

I fixed this

Reduced the distance from the top of the support to the model.
