I have tried quite a few different bed surfaces. At the moment I have glass on the bed and use diluted with water PVA glue and that really makes prints stick.

If it is a stiff print and bigger than 1.5 inches it is very difficult to get off the glass. So bigger prints I just clean the glass.

If prints are difficult to get off I put water around the edges and after about 20 minutes they come off.

So looks like I stay with a glass bed surface unless something better comes along.

So no raft needed when using a glass surface.
