Prusa XL - Changing the Nozzle from 0.6mm to 0.4mm to reduce some stringing issues

This is short video to show the quick steps to changing the nozzle on the Prusa XL 3D Printer. It is fairly easy, although not a quick change nozzle like some other manufactures are starting to provide. Since I have seen others change to a 0.4mm nozzle and get some improvements in the overall stringing issues I decided to try it myself. At the end of the video is a stringing test comparison between the 0.4mm and 0.6mm nozzle. The temperature, fillament, and retraction settings are the same. Using 0.2mm layer height for both. This was done using the IS beta and PS alpha versions.
Update: I have also tried the RC1 Prusa Slicer and it seems to help with stringing on both 0.4mm and 0.6mm nozzles overall.

Good video! You pointed out a couple of things where I made mistakes. ONE do not over tighten the set screw - I crimped the tube on the nozzle, and the filament will not flow correctly, SECOND redo the nozzle alignment steps
