While I’m waiting for more nozzles to arrive in the mail, I’d thought I’d ask the new community here for their thoughts on my issue with the Swiss Micro All-Metal hot-end. Since upgrading to it, I haven’t noticed a remarkable difference between it and the stock one in terms of nozzle wear and clogs. I’ve reassembled it, I believe twice now just to make sure everything is to spec installation-wise. I also haven’t ruled out human error and have tried adjusting settings like retraction, as well as trying to not leave filament in it while cooling down. However, the nozzles and heating block still are covered in blackened goo, and the nozzles only last for about a month (with fairly light, and infrequent use).

I should also mention, I’m not using exotic filaments or crazy combos, just PLA or PLA+ kept in dry, sealed storage.
