Ok thanks, I will try it with UHU stic delivered in Ultimaker S5 accessory box.
Do you recomend to use raft or brim? I would prefer brim because it's eassier to remove it than raft. In other words the raft became welded on the part, may be I have some parameters worng.
On the other hand I use raft to get air between the glass and the part to avoid any glass damage, but some times doesn't work and the resolt is the raft welded in the part
