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.
Nozzles shouldn’t wear out that quickly if you are not printing abrasives. They should last you hundreds or even more printing hours.
Regarding clogging: what hotend do you use? Are you sure it’s not heatcreap?
I see… what kind of fan do you have?
Stock Ender 3 V2 fan
If you are experiencing leaking around the nozzle and heating block, you probably have not properly seated the nozzle. Remember to not completely tighten the nozzle until it’s been heated to a higher temperature (say 250C) then completely tighten to get a good seal.
When you say light use before nozzle changes are you seeing the nozzle hole get larger or the tip worn down?
I may do another complete disassemble and reinstall again just to triple check. And the nozzle appears the same just clogged and dirty
After you address the leaking, you may want to spend some time tuning retraction. For MicrSwiss hot end, the retraction settings is lower than the usual Ender3v2 setting - for my CR-10 Mini I have the retraction set to 2.75mm.
Yeah I agree its probably not assembled well. Even if you wear out nozzle it will not clog. Clog will happen if you print on too low temp or if you have huge retractions with insufficient cooling, or just bad assembly
Would you mind commenting a photo of your hotend up close? It could be many things, but in my experience these hotends aren’t very good.
Switch to the NG!
?
Micro Swiss NG. It’s a direct drive extruder that works like a dream and you can print much faster with it.
Ohhh okay thanks for the rec! I was searching “3d printing NG” and wasn’t finding anything
No problem! I highly recommend switching to Klipper, also, if you haven’t already! What kind of printer do you have?
Ender 3 v2 with octopi
Nice! There’s so much stuff out there for that printed. I’ve got an Ender 6. I replaced the motherboard with a BTT Manta E3EZ+ CB1, ez2209 drivers, a 7 inch capacitive touch screen, and added the Micro Swiss NG. I’m still fine tuning all of my slicer settings, but this thing runs so much smoother now.
