<p>Ultimaker Cura offers a platform support type of “<em>touching buildplate</em>” which enables the printer to only make a raft for parts of the object that should be touching the build plate. It also offers “<em>everywhere</em>” for any object that might be hanging over the build plate.</p>

<p>I have a need to only offer support for overhangs up to a certain z height, such any overhang located at a z-point of 4&nbsp;mm or below. Is there a software that will enable this, either as a setting/addition to Ultimaker Cura or just a G-code export for Pronterface?</p>
