Undesired support XY expansion and corresponding pillars
Hello,
How do I prevent the slicer from generating supports outside of the part, thus creating these unwanted support pillars coming from the part?
Tried many settings to no avail.
Thank you.
With 2.3.x and earlier you pretty much can’t. You might try using a very tiny amount of painted on support. A lot smaller than you think. The support algorithm is very aggressive though so while that might work it will be tricky.
PS 2.4 which hasn’t been released yet is tackling support issues though and it has a snug support option. That is designed to work in these cases. However it’s not even alpha release yet so you will either have to wait like most people or you can pull the source from GitHub and compile it yourself.
it shouldn’t be too many weeks now for the first alpha though from what I understand.
Thank you
Thank you for your reply. It's a bit disappointing, as this is a a very basic function. Simplify3d has the "Horizontal Offset from Part" parameter to deal with this.
Appreciated your workaround. I'll try it next.
Thx,

One other thing you can try is to set the support pattern spacing down from the default ~2mm to something lower, between 0.5-1.5mm. As the support expands out it uses the spacing parameter, make it smaller and it expands out in smaller increments. I’ve had some success doing this but it does depend on the model
That has the downside of denser support though. It can be useful on a case by case basis and remember modifiers can help by tweaking settings in specific areas.
Thx
Thank you for the idea. Will try next.
