I don't see the point of overhang test below 55degree as most printer should be able to do that. So directly testing 65 and 75 degree as a way to calibrate speeds and fan speed (or compare ducts variation, which I've been playing with on the ApolloLander shroud)
If you post a make, I'd be curious to know what shroud and speed/acceleration you used (and I'm sure other would appreciate it)
I'm still pushing speed slowly to find the quality failing point, and the actual failing point, but so far I was doing 10~15mm/s speed on external perimeter (defined in the overhang slicer speed settings), 50mm/s internal perimeter, with 3 perimeters/walls (infill speed doesn't affect it really, had it at 100mm/s)
And up two 2K acceleration with good results, at least for 65°, 75 wasn't as perfectly clean but not bad , still tight and no falling loops.
with 65° 0.2mm layer height seem to be small enough to get a very decent overhang
with 75° 0.1mm layer height may be needed, but 0.16 wasn't catastrophic (no falling loops)
