Tree Support connects through the whole model

This model is relatively complex and needs a lot of support. I used tree support and in the layers 56 to 69 all the support infill goes right through the whole model, what results in drasticly reduced skin quality. It seems like the supports want to anchor into the model to get stability and i cant find a way to deactivate this feature/problem. Is there a setting to switch on or off? The only way i figured out yet is to reduce support infill to 0% but i dont want all the supports to collapse ...

It 'll be more comfortable for us if you provide us with the stl file because :

 

- we will see what happen on the upper layers above the pictures you provide (zones which need for support or not)

- we can try out somme settings to try to fix it if possible

These are all the files I can provide. I hope it helps!

I succeed to avoid this by changing the Support X/Y distance from 0.7mm to 1mm

 

To do this you have to change in the settings visibility the Support X/Y distance  by clicking in the checkbox

Then in the settings modify the distance from 0.7 to 1 (or more if you want). This distance is the minimum one between the support and the object on the x and y axis. This maybe avoid the collision which occured in your trials

Thank you for your reply!
I tested your suggestion and had to bring up the "Support X/Y Distance" to at least 1.3mm to get rid of the crossing support lines. I am a little bit concerned how the almost double XY Distance will affect the print but I guess I will test to print it with these settings.
If you still got the settings of your tests I would appreciate if you could share all of them.
However thanks for your help!

In fact I modified 2 parameters from your 3mf project file

 

- the support x/y distance from 0.7 to 1mm

- the support overhang angle from 60 to 50 degrees, this improved the result as at 1mm for x/y distance the collision was still there
