Organic support with variable height

[F-CJPJ]

Description of the bug

I sliced with organic support : display is ok.

then I added the variable height , then I sliced again with the same support configuration.

The display shows that branches of the tree don't touch the ceiling of my part. See screen shot attached.

Project file & How to reproduce

As explained above, the slicing with variable height shows that support branches don't touch the part !

With fixed 0.2 mm height, the branches are ok.

It might be a display issue or a slicing issue.

it can remain open as a feature request

@agravelot, at the moment we let it in this stage. But it is on our list.

Can someone explain why this is difficult to do? Not implying that it isn't, just want to know.

Hello

In my case, when I mentioned the issue, it seemed to work BUT the top of the "trees" did not touch the part to print.

Now I tested again with alpha6 and the same part, but I can get variable layer height.

I don't understand.

Just a +1 on this. This would be amazing to have fixed.

[muhmuhhum]

Also a +1 for me. Tried to print miniatures and want to printe the base in a lower resolution thant the rest to reduce printtime

[foggyforests]

+1 for me as well. Variable layer height with snug supports seems to take more material and time compared to organic supports. Would be wonderful to have fixed. Thanks for considering!

I understand the considerations that need to be taken for variable layer height with organic supports. But we should still be able to have variable layer height when those layers are above any of the printed supports.

[freeformz]

+1 on what @boodaah3d mentioned. Should be easier to initially support variable layer height when the heights are above any organic supports. Although the UI would probably not be. :-)

I don't know if this is of any help but I came across this error today; along with a solution to my specific problem. In my case I was slicing a file that I made for the MK4 with a .4 nozzle and 0.30 layer height and 0.30 printer settings profile. However when I tried to transfer to an input shaper profile with 0.20, I got the error. Then I realized that I still had the 0.30 layer height in the range height modifier. Once I switched it to 0.20 to match the profile, the problem went away. Hope that helps.

wouldn't it be simplest to make the organic support thickness follow the perimeter? I take it then infill combining also doesn't work with variable print height?

[vgdh]

+1 I want this feature

I've also found that paint on supports get ignored when a height range modifier is used with organic supports. You can see what I'm talking about in the vid below.

+1 for organic supports with variable layer height.

Variable layer height is the best trade-off between speed and quality. And organic supports solve many use cases, where normal supports don't work. Combining both would be a great improvement!

+1 for organic supports with variable layer height.

This would make life a lot easier
