Cura with Snapmaker 2.0 Printer - Custom Nozzle Size
If Cura knows the Line Width, the Layer Height, and the Filament Diameter (an accurate measurement), then that's all it needs. No matter what the nozzle size is, it is the volume required by an extrusion and the volume of a length of filament that drives the E numbers in a gcode file. You will want to make sure your E-Steps are close to perfect. The small nozzle is less tolerant of minor differences.
I haven't printed a lot with a 0.2 but I noticed the retraction settings needed to change. The smaller hole doesn't allow for quick response backward and so I needed to lower the retraction speed in addition to the retraction distance. I would start with a lower print speed as well.
It's all a balancing act and your printer is different than mine. Once you scrap a couple of pieces you should have a good idea of what works well.
