Supports not... Supporting?

[Tetraodon]

I'm really struggling to get good looking areas under supported regions - to the point where there's not much point in having supports at all. I've tried upping the support density, however that just lead to them sticking on more and no better looking outcome. The upper vertical separation layers is typically 1, though for the black PET-G print, it was set at 2 to see whether they'd be easier to remove. Some examples:

This ended up printing in a V-shape (is actually a cylinder)




(it's not in focus but here the supports actually got stuck to the object)


It can also hardly bridge a few mm long (on both ABS and PET-G)



Any suggestions for ideal settings?
(factory file attached - I'm not sure what has caused the mess in the logo on the g-code so will be checking that)

You have some very small features there that you are trying to support. When working with tiny features like that, you need to make sure that your support pillar resolution is small enough to handle them.

So go to tools --> customize support structures, and then change your pillar resolution to 1mm. Then click generate automatic supports. You will see that it does a much better job adding support into all of the needed locations. Of course, if you intentionally wanted it left out of those thin slots, then you can disregard what I said

It is printing with supports (unfortunately below is the only pic I have of it, but these were likely 2mm if I remember correctly), it's just still printing really poor bridges/overhangs with them.
