Can't get the 0,2 nozzle to work

Hi. I have tried to do a pressure advance test with the 0, 2 nozzle. And it looks like not enough material is going through.

I looked in the settings for generic pla. And it say max volumetric speed is 1,6. Is that right.

My printer works great with the 0,4 nozzle. But when I try with 0.2 it doesn't work. I looks like not enough material is coming out.

It's a new nozzle. I have changed the settings for 0,2 in the printer and in bambu studio.

Is there anything a need to know to get it to work

I'm using a A1.

Thank you.
