Just a quick question… When I cut through an entire piece (layer by layer) how do i create those little spots where the piece is connected so the part doesnt drop out. Like in allteds aluminum solderless motor mount video. I am going to be doing some cuts where ill need to do that 
thanks
In EstlCam when you select a tool there is a holding tab option.Just click in a few spots. Give it a try let me know if you have any questions.
