Support structures supported

[calad 0]

Hi. I have been using cura, then slicer and now cura again after I learned how wonderfull cure is.

My problems is that I need support structure for my object, but during printing support structure randomly breaks off from glass. Brim and raft solves this problem but I would like to have my main object without brim and raft because when I take it off it leaves sharp edges.

So question is how to print to keep support structure on plate without coming off during printing? Easy solution would be a pluggin that generates brim and raft only for support structure.

I use PLA on heated normal window glass. Temp for first layers 210 and 80, later 180 and 60.
