Yep, that was the answer. Disable the AA 0.4 core and now I can use the AA 0.8 core. Now I can print at 0.3mm and 0.4mm. Thanks so much!

Hopefully my title makes sense. I am having a hard time trying to get Cura to behave. I installed a brand new AA 0.8 nozzle to print PLA at a faster rate. Before this I always used an AA 0.4 and my prints are great for it. I have some items that I need that quality isn't a big deal and I figured a 0.3 or 0.4 profile would be perfect for it. However as soon as I selected AA 0.8 on Extruder 2 I only have 1 option "Fast - 0.2mm". Not exactly what I was looking for. Does anyone have a profile that will work with my UM3 for PLA that will give me a 0.3 and/or 0.4 option? Thanks!
