I've noticed that rafts and supports may not be subject to the same ooze control as what is set up in profiles. Here's a print I did today that illustrates what I've noticed:stringing marked 1 and 2. This from one part of the raft to the next - not a problem really, but pointed out for information.The print is of six separate models all running off the same profile. Look at the
Looking at the sequence A to F. The end of the previous layer is at A. The nozzle runs to B and prints a bit of support, then runs to C to print more support, and finally to D to print the third bit of support on the bed. There's stringing from B to C that is deposited on the surface of the model at F. Similarly, there's stringing from C to D that spoils the surface at E. And the stringing stops when the support material is no longer printed. There's virtually no stringing elsewhere on the models. The worst bit is on the chimneys.
So, from the above, I must assume that support material does not have ooze control on it...which I believe is a bug. Alternatively, it needs separate ooze control!
Now I know this is an issue, I can place models to print with any support material facing each other so the stringing runs through fresh air. But I shouldn't have to!
