My sparse infill walls are weak. They seem to lack the different layers do not connect well. This is 3% rectilinear infill
What causes this? Is there a setting to adjust this?
Looking at the seam and outer wall quality of the inner circle, you may be better off drying that spool first.
Regarding the infill, is “combine infill” enabled? If yes, disable it as it does not work properly in Studio. If no, reduce infill print speed to inner or even outer wall speed.

Hi EnoTheThracian. Thank you for your reply.
-Combined infill is not enabled, so that can’t be the issue.
-The spool is dry (twice, in the last 24 hours) and the dryer reads 8%, so it is unlikely that this is the issue either.
-The internal infill speed is 50mm/s, the same as the outer layers. Is that too high?
The material is LW-PLA-HT so I do not expect perfect walls, however this infill walls are just not right.
Would you have any additional suggestions?

Hi @iflyrcsl ,
Thatvis a rather crucial bit of information 
Unfortunately, I do not have experience with LW, i.e. foaming materials.
I do remember that extrusion consistency is quite important from forum discussions though. So I would probably use the slicer previews (fan, speed, flow and line width) to compare to the various features of the model and then try to get consistent pictures which match the good areas of the print.
Sorry for being unable to give better, more targeted advice on the LW filaments,
Yours,
Eno

No worries.
Thanks for your comments and suggestions so far.
What baffles me is that the setting for the infill are set identical to the settings for the outer walls so my intuition tells me that they should come out identical, but they do not. So I imagine that there is a settign somewhere that affects the quality of the infill wall. I just need to find it.

Do you have identical line widths? That is overlooked frequently as it is in the Quality tab.
Just checked now. I thought they were, but not quite.
The outer wall is 0.5mm and the sparse infill is 0.45mm.
I’ll now adjust this to 0.5mm and see what happens
