Tips for 0.2mm extruder head?

Hello everyone. I'm brand new to 3D printing; my recently purchased R2 is my first printer and I'm still just starting to figure this whole thing out, so please forgive me for my complete ignorance.

I just picked up an 0.2mm extruder head, and before I try to use it I was wondering if anyone had any tips or warnings? I'm using Cura 3.2.1 on Ubuntu, having followed the Mac instructions to load the profiles. I believe I will need to modify the printer profile (or create a new one) to set the new nozzle size, but other than that do I need to do anything else, like adjusting the flow rates or anything?

 

Do you mean I should reduce the speed at which the extruder moves in X and Y? And by "too" I assume that means that I was correct when I suggested adjusting the flow rate? Do you have any guidelines for how much I should adjust the flow rate? Are we talking about turning it down to like 90%, or do we need to take it down to 25% since the hole in the extruder is a quarter of the area?

 

Just adjust the nozzle size and maybe reduce speed in the profile.

I've been successfully printing 0.25 without speed changes though aka 50-60mm/s or so.

 

Cool, thanks for the tips guys!
