Slicer adding material on the inside of a Vertical slot

Posted · Slicer adding material on the inside of a Vertical slot

I have been using Cura for over a year and this is the first time I've experienced this type of behavior in the slicer.  I could be something I'm doing but it goes away if I print it in a different orientation.  I thought it may have something to do with support but it happens even when I turn the support off.  The angle starts at layer 119 and adds extra material in the vertical slot.  Any Ideas?

    In the Experimental section of the settings there is "Make Overhangs Printable".  You need to de-select that.  It adds a chamfer to horizontal surfaces (when possible) so they don't require support.  I haven't seen many models that need it.

    Wow, thanks so much I would have never found that.  I never paid much attention to the experimental section so I'm amazed that it would be set, maybe it was the default?  So originally I had supports on so why do you think that this experimental option would take presidence over supports?  Thanks again!!!!

    The default is "off".  Every once in a while though it gets turned on.  If you open a 3mf file and it is set to "on", and you don't notice then it can become your default.

    Another setting that can cause unwanted effects that are hard to figure out is "Remove All Holes".  It has it's uses to fix some specific model problems, but not very often.

    Not by itself though.

     

    It can happen if you load a project-file from someone else. That can change your settings to match theirs.

    Yessir.

    "If you open a 3mf file and it is set to "on"..."

    That's what I was trying to infer.  I guess I missed it.
