I attempted to print a 2 color PLA part using AMS with a .02mm nozzle, and ran into issues with the filament being stuck above the hotend- (i believe it was).
The filament was fattened from heat, and the AMS could not pull it back out. This seemed to occur at about the same layer height on the prints I tried.
Would this mean the nozzle temp is a bit high- or perhaps my cooling fan needs to run more/higher speed?
Thanks for any ideas,
