I've been using Slic3r on and off for a couple years. The ons are because of the extraordinary control it allows over the printer and print. The offs are because of the frequent crashes or just malfunctions.
I haven't used Slic3r for about 6 months and decided to try it yet again with a fresh install of the latest stable release on a very recent Win 7 install. It did what it always does. It worked beautifully for a few parts, then started screwing up. In this case, I tell it to use a raft and no raft appears in the gcode. I tell it to use a rectilnear support pattern and it gives me pillars. I have run into this before and the solution was to delete the customized preset file in question and recreate it from scratch and then Slic3r seems to work again.
Is it me doing something wrong, or is this a 2 or 3 year old bug that has yet to be fixed?
I have noticed that this sort of behavior seems to be less of a problem when I install by compiling the source code under linux...
