Tree support Issue

Posted · Tree support Issue

I have a problem with tree supports. The support do not make contact with the model in all parts of the print, thus causing the model to disconnect from the support. I tried increasing the support bottom density from 10% to 40% (still have to test it out) and i also selected Z ovverides X/y and set a Z distance of 0.2 and top distance of 0.2. Although the support seem to improved when i see the slice preview, there still is a visible gap. any ideas? 

This is a 27 hour print which i already tried 3 times, but i just noticed what the actual issue is.

    Hello @Distracto

    You have the Support Z Distance set to "0.2".  Typically it is set to "1 layer height" in order to keep the plastic of the real model from bonding so hard to the support interface that the support becomes part of the model.  That gap you are pointing at in the last image does appear to be 1 layer.

     

    If you have a dual extruder printer then the gap is often not required (Support Z Distance = 0) if the support material is non-compatible with the model material.
