Bug: supports on build plate only #1340
Comments
I tested some more settings and the results are even more wrong then before. If you disable sheath around infill and set pattern spacing to 4 and the rest the same as picture.
I have tested this on the portable version of slic3r PE version 1.41.1-rc. |

Thank you for report. This is because of how the algorithm for calculating support works. I thing the algorithm is trying to stabilize the support and depends on pattern spacing too because slicer do not cut support in middle of space between supports. That is why they can sometimes appear where they are not expected. |
This always appears on the object for me no matter what I change. I use 1.41.1.
In this case I can't even remove the support and the surface quality of the object is basically destroyed on the inside:
It gets worse if I enable "sheath around support": |
update with PrusaSlicer 2.0.0The problem is still there.

I have just encountered this problem with v2.0.0+. Steps:

This issue has a duplicate |
Still there in 2.2.0-alpha2+. See attached project. |
This is still happening in 2.2 full release. |
Tested with the current master. The support columns are trimmed to not land on top of an object. However this may make the column too small to be stable.

1) If "support on build plate only" is enabled, the support columns are newly trimmed to not land on top of an object. However this may make the column too small to be stable. 2) Support enforcers newly take precedence over "supports on build plate only" and over "don't support bridges". 3) Some refactoring of the support generator code for clarity: Reduced some of the worst spagetti offenders.

Version
1.41.0 x64
Operating system type + version
windows 10 home x64
Behavior
there is a support structure on the object while the supports have been set to bed only
to reproduce: enable supports and enable sheath around supports
I excpect that there is no support on the object
Actual Results
Is this a new feature request?
