Soluble/PETG mixed material hand print failing on fingertips
I'm doing mixed material print on a PRUSA XL 5 tool. I'm only using 2 of the heads. One has PLA for supports, and one has PETG for the model. I do this to make the supports very easy to remove. I've done this fine with other models, but with this particular model it ruins the fingertip for the forefinger and the pinky, and they don't stay on the supports. And because there's no base there, the excess PETG gets smeared on the adjacent fingers and down the supports, making a mess.
What it needs is the support material to cradle it higher up the sides of the fingers, instead of just supporting the bottom, but I can't get it to make the supports go up the sides of the fingers, either by changing the overhang number (I've done as low as 10 degree) or by putting a support enforcer on the fingertips. It always just supports the bottom of the fingers only.
How can I get the support material to cradle the fingers higher up the sides with the support material??

That's one of the problems with mixed materials. If the contact surface is relatively flat, no problem. But if it's angled, material 2 just slides down material 1 and you have a mess.
Did you try organic supports? They may work better in this case.
Not sure without seeing the 3mf project why paint-on supports don't work.
