With the Sparkx i7 easy nozzle change I now can change nozzles as easily as filament. With the quick change nozzles, I can easily switch to a different nozzle size, e.g., 0.2mm or 0.8mm. as easily as I do filament changes (for color or type). For all my other printers (don’t ask how many) I could change the nozzle but I never do because it is a bit of a hassle. Not anymore. See the attached video.
