I have just started to suffer from "Fir" after switching to a Micro Swiss hotend with the "high quality" nozzle that it came with. oddly enough the cheap nozzles I had used before almost never had this problem, to the extent I did not even know it was a thing other than normal stringing. but good to see your guys inputs here has given me great insight, I started to suspect it was the nozzle but was hesitant to try since its brand new and had no reason to preform badly.
