From what I can see of the model, standard rectilinear supports instead of tree would be a lot better. Since your overhangs are all 90 degrees, it would create a solid support platform, and they’re stronger overall. The rounded area you can see through the supports, make sure to face towards the cooling duct if it’s unsupported. Reducing your layer height will help with overhangs as well.
Yea I was thinking of starting to use it less but I dont really see the point in disabling it (exept for time), if it doesn’t improve surface quality. I will continue to use it because I like when the nozzle stays clear of the part when traveling…
