Simplify3D User Forum

I have 2 extruders, Front and Rear. I set the infill extruder for the Front to Front (so the shell and infill are the same). I then go to the Back extruder and set the infill extruder to Back. If I return to the Front extruder, this is now set to Infill Back. Set that to Front and return to the Back extruder and that infill is now set to Front.

No matter what I do I can never get the infill to be the same as the shell material for both extruders at the same time, whichever material I select as Infill for one tool is also applied to the other tool as well.

Is there some setting or checkbox I am missing?

Is this a bug in the new version? (I know I have done infill correctly in the past but have only just started using Simplify again after a long break and just updated it)

Is it possible you have your 2 processes grouped together? If they are grouped, then those settings will be changed in both processes (see here: https://www.youtube.com/watch?v=EbQfifnzL4Q)

So you would need to ungroup them first, then make the change
