ah ok, yeah that is weird then, but depends if you used some rough filaments in there or not, to my knowledge the a1 doesn’t come with hardened steel (but not 100% sure on that), but yeah it’s strange as it’s so new, on my X1C i’ve had it for a year and a half and have ~2400 hours of print time, so that extruder served me well and i have no complaints on having to replace it now
