Excluding support from a certain area or past a certain height

Posted · Excluding support from a certain area or past a certain height

Just discovered TREE SUPPORT - awesome.- never knew it existed.


QUESTION> I have a model that needs support - but at the very top of the model is a large vertically oriented 6mm threaded hole. The overhang of the profile negative thread teeth is making cura think that support is needed there. So its filling the hole up with a tree of some sort. Is there a way to stop supports after a certain height or in a certain area on a model. THANKS!

    Well you can probably change the "support overhang angle" to 80 and that should do it.


    There is also a support blocker:

    1) Create a cube model or download one from thingiverse.  Just a perfect cube.  Add it to your build plate.

    2) In cura do "preferences" "configure cura..." uncheck "automatically drop models to..."

    3) click on the cube and click on the 2nd from the bottom tool on left side and choose the last option: "don't support overlaps".  This makes the cube a support blocker.  Now you can use the move tool (top tool) to move it up and around and you can use the scale tool to change it's size and if you place it to cover any red surfaces (surfaces that are red in prepare mode normally would get support) then it will block support for that area.  So you can make the cube small and skinny and tall and place it where the threads are.
