Alright so here's a new one... In MB 3.7 I could set the infill height to a multiple of the layer height, e.g., layer height of 0.2mm and infill height of 0.4mm and it would do a double thick infill every other layer. In 2.4, even though I have it set this way, it just prints infill every layer. Is this something that's not supported in 2.4?

In my "miracle.json" file I have this...

"layerHeightMinimum": 0.10,
 "layerHeightMaximum": 0.40,
"layerHeight": 0.20,
"infillLayerHeight" : 0.40,
