I have a file that prints perfectly when the infill is set to 0%. When I print with 100% fill and I don't change anything else, the print gets a bit more "puffy".
One wall that is normally 7.25mm when printed hollow turns into 7.59mm. Another one is 8.1mm and moves to 8.4mm when solid.
Has anyone else seen this issue? Any ideas on which settings to check?
