Thanks.

Board is ready. Beautiful result. But measuring shows that the first centimeter has shrunk over all by 10% and some more on the edges where it curls up.

What i'll do now is
- print it laying down in stead of standing up (the board is 130x105x25).
- print the first layers with brim very slow (thanks for the advice).
- Then after 5mm i lower the temp of the glass plate to 30 degrees C.

Any more suggestions?
