This may help some of my rafting issues. On the XYZ, the slicer doesn't seem to do rafts quite right, and I can't ever get them to come off, which sorta defeats the purpose of a raft. Raising the object a mm or 2 before slicing and adding supports may solve some issues I might have.

On a side note, I have to manually add skirts to any builds that have "spires" (tall thin segments that the ABS doesn't cool enough to support layers above it). I add a 1 layer wide cylinder around my object to give the extruder something to do while it's letting the spire cool. Does use more filament than not, but far less than having a print fail 4 times right near the end.
