print doesn't separate from base

[chaotic1]

I am printing small and often delicate models using Hatchbox ABS brown filament. Printing at 265ºC but have tried lower temps as well. The model doesn't separate from the raft. I have not had this problem with PLA. I was thinking the temperature was too hot but when I reduce it (2 or 3º increments) it either doesn't print out completely or it still doesn't separate. I am very new to this and I am using an M3D printer to make 1:48 scale furniture. Have settings for lowest fill. What else can I try?
