Prusa Slicer 2.6.0. - Crash organic supports
I tested several 3D-models I never printed successfully, because they need supports and the surface was too scarred to my opinion (PETG). The new organic supports changed a lot and now I get back to all these parts and try to print them. I really love this new supports.
But on some 3D-models I get problems. When I started the preview for slicing the process stopped always at 70% and the slicer hangs with high CPU load (see pic.). If I take another support style than organic supports it works without failure. Sometimes you have to kill the Prusa Slicer then by force with the task-manager, so that you don't get additional tasks when starting Prusa-Slicer again, which will lead to complete CPU overload when you repeat this several times.
I am not sure, but it looks like that this organic supports sometimes have problems in addition with rafts I placed under the part to get more contact surface.
Could anyone confirm these problems? Maybe there is a workaround? I wonder that only some 3D-models have this problem.

Known issue with rafts in 2.6. Reported on the Prusa slicer GitHub several times.
RE: Prusa Slicer 2.6.0. - Crash organic supports
Thanks for the reply.
So I have hope that it could be fixed in the future. Until then I try to find a workaround and report if I could find any.

There are several issues (both opened and closed) but here is one from recently with several replies https://github.com/prusa3d/PrusaSlicer/issues/10858
RE: Prusa Slicer 2.6.0. - Crash organic supports
Wow, thanks again for the hint.
The other users already made several tries, so I don't have to test all things again with the same result.
I tried to raise the object in Z-axis to prevent rafts and let the supports grow to the object. But Prusa Slicer does not support it, how I found out in another thread where you explained it ( https://forum.prusa3d.com/forum/prusaslicer/place-parts-above-the-print-bed/#post-166269).
One thing that worked is to turn the object a few degrees around X- or Y-axis, so that the touching surface to the bed is very small. The gap will be filled then with the organic supports without using raft.
But in one case I would like to have the same orientation of layer structure for single parts that will be assembled together later on. Maybe I could find one more solution?
RE: Prusa Slicer 2.6.0. - Crash organic supports
I made some tries with different 3D-models and finally found accidently a work around that let me use organic supports together with raft on this few problematic 3D-models.
Place the 3-D-model on the bed and make all adjustments you would like to have in Prusa Slicer, but do not activate the raft.
Then turn the 3D-model around X-axis. One degree will be enough. After that activate the raft and start the slicing.
To take the Y-axis worked not (for me). But if I turn 90° around Z-axis and then turn around Y-axis (-> former X-axis) it worked again. It looks like the problem is somehow in the geometry of the 3D-model, so in other cases turning around the Y-axis might work.
If I turn the part back to the original orientation, Prusa Slicer crashes again...
