Adjusting locations of organic support bases
Hello! Any ideas how to force the base of the organic support in the pink circle below to be on the INSIDE of the model like the others? I've tried negative volume, adding a very thin strip on the print bed there, painting that strip as support blocker, adjust some of the advanced organic support settings, etc. No luck thus far!
RE: Organic support base defaulting to OUTSIDE the printbed...
Seems like there is a coding issue if PrusaSlicer is placing the organic support bases outside the printable area when there is untouched room for them on the inside of the model. Any thoughts? Is there a workaround?
RE: Adjusting locations of organic support bases
no one can help? I have the same problem, I tried adding support blocker objects where I don't want the organic supports to grow outside of the print area - but that does nothing.
RE: Adjusting locations of organic support bases
No, no one can help. It’s a known issue. There is at least one on the PRUSA Slicer GitHub. For the -I tired model I would suggest using snug support and making the first layer expansion for support zero.
Also blockers and enforcers don't work like that and never have, and are not supposed to. All a blocker or enforcer does is define areas on the OBJECT that requires or should not be supported. Once that areas are marked (either by a modifier or by painting) then the support algorithm takes over and generates support based on your other settings. So if an area above a blocker needs support it will generate it right down through that area. They are not keep out areas.

This is easily mitigated.
If you haven't figured it out yet, or are still unsure, shoot me a PM with your "zipped" project and I'll show you.

Organic supports are rarely ideal for practical prints, they are really useful for irregular shapes/models/toys etc. For most practical parts snug is the better choice, or for very tall ones, grid.
But for a part like yours I would normally design custom supports into the original CAD ... like this exaggerated example:
Two support structures with a single layer bridge on which to build the overhangs.
Cheerio,
