Cannot remove support from single object in multiple object print:
Steps to reproduce:
Add multiple different models to be built.
Use the support tool to generate automatic supports
remove supports from various objects/places
click remove supports again to finish the process
click prepare to print
Note that supports were only removed for the previously selected object when prepare to print was clicked not the other objects.


This is one of the main reasons for using simplify3d. I really like the toolpath quality too, but support removal/addition was the real draw for me. Seems like the check is only for the current object rather than iterating through all objects. Should be a simple fix. (hope I didn't curse it! )

Your process settings will also affect what objects get support added if you have "support generation" enabled. So for example, if you have 3 parts and only want 2 of them to have support structures, then you should use 2 processes. The first process has support generation enabled and then use the "Select Models" button so that it only applies to the models you want. Then create the second process with support enabled.

If you have support generation enabled for a model, it's going to add support. If you're still having trouble, post your factory file and I'm sure someone can help you.

That was never the case in the 2.X versions. Did they change it? If you look in the process it even says in automatic support generation "only used if manual support is not defined"

That is how it worked in the old 2.x version as well as the new 3.x versions. It has always worked that way. I have both on my computer, so I just verified this myself.

I think you are misunderstanding the comment, "automatic support generation is only used if manual support is not defined". If you delete all of the manual supports, then there is no manual support defined! So it will add automatic support. If you added 1 single support pillar manually, then there IS manual support, so if you slice, only that one support pillar will be present.

So I agree with Carl. If you some models to have support and some without it, then you should create 2 processes and make sure support generation is disabled in one of the processes.

I have done literally hundreds of multi model prints and have never once had to make 2 profiles, one with support and one without. This seems strange to me.

This was actually a transient bug. It was my understanding, and seems to be the current way it's working that if I remove the support with the remove tool, all is well. This one time, it wasn't. I expected to run into the problem on a later print, and was surprised to find it wasn't there. Not sure what got borked in ram, but something certainly was! Lesson learned. If there's a really really really painfully obvious bug...restart the program. Transient/intermittent bugs are the hardest to find. I get it.
