Support material acting funny
I am currently working on a large format printer trying to use prusaslicer to print a ~2ftx4ft print. I am using a large nozzle and I am trying to print the support material without using a sheath around the rectilinear patterned support material to make it easier to remove (since the nozzle is very large).
The problem is that the support material won't generate properly without the sheath around it. I am not sure why. Does anyone have any tips?

Not sure what you are referring to by sheath. Could you save your project file and then zip up the resulting.3mf file and attach it here. Needs to be zipped for the forum to accept it. With the project file we can see the slice and settings you are using and debug things much more easily and quickly.

Thank you for the quick response! I am unfortunately unable to share the exact file along with the model for this is for a customer who does not want his model shared. But I have taken a screenshot of the setting I am referring too in prusaslicer.

I’ll repeat, what do you mean by sheath, please indicate precisely on your slice what area you mean by sheath. Also you could cut the top of the model if you can’t share it or cut a small section out as an example. As long as it still has the ‘sheath’ and the same settings to demonstrate what your actual issue is.
Anyway I’m off to sleep so will check back in the morning.

Thank you for the speedy responses once again! I am also off to sleep for the night so I will make sure to post more information regarding the “sheath” tomorrow.
until I have time to post a photo of the comparisons - checking the “sheath” box enables a single perimeter to be printed around the support pattern to increase its strength. I am trying to print WITHOUT a sheath so the support material may be easier to remove. If I do not have the sheath box checked prusaslicer will not slice properly (the first photo in this series depicts the flaw in the slice without sheath box checked)

PrusaSlicer has had some issues with proper angle detection for deciding when to generate support. Play with the angle a bit (overhang threshold), or enter ZERO to let it decide automatically. But when changing the angle, don't be surprised to be surprised it doesn't make a lot of sense.

Oh - and it would be helpful to show the "working" and "non-working" feature you are concerned with. That first image of Plicer looks perfectly okay to me. What aspect of the supports are not 'right'? Base, tower, interface? A photo of the actual failed print can also be useful.

I am sorry about not depicting the problem very clearly; there is ~10 layers no no support being generated below. It generates the first layer of support, then stops for ~10 layers and starts generating again in thin air with nothing else beneath it.
RE: Support material acting funny
I've never seen that. As neophyl said, without a model as an example, and the setup in use, we probably won't be able to help.
Almost always, the problems people face are self induced: a broken model (some error in the vertices or faces); or some setting used that shouldn't be used with the other settings; little things like resolution vs accuracy, too.
RE: Support material acting funny
Are you talking about these odd looking regions? If so, I don't even know why that area is being built without looking at the model itself.
