Depending on the printer and nozzle, you can further lower the minimum layer height used in adaptive layers.
Hover the mouse over the printer icon at the upper left of Bambu Studio, click the edit icon once it appears to enter the machine settings.
Navigate to the Extruder section and manually enter 0.04mm in the minimum layer height.
You can go lower, but extruder control can become a killer below 0.04mm.
Also, it may be a print or even nozzle killer for filled filaments. Haven’t tried those for actual min layer height.
