I’m planning to experiment with the 0.2 mm nozzle on my K2 Plus and wanted to ask for some real-world feedback before I dive in. I mainly print PLA and PETG, and I’m curious how well the K2 Plus handles such a small nozzle size with these materials.
If you’ve already tried the 0.2 mm nozzle on the K2 Plus, I’d really appreciate hearing about your experiences:
How reliable was extrusion at that diameter?
Did you need to adjust flow, pressure advance, or speed significantly?
Any issues with clogging, under-extrusion, or inconsistent layers?
Recommended slicer settings or profiles?
How much slower did your prints get compared to 0.4 mm?
I’m especially interested in whether PETG behaves well at 0.2 mm, since it can be a bit stringy and sensitive to cooling.
Thanks in advance for any tips or insights — I’m looking forward to hearing your experiences with ultra-fine nozzles on the K2 Plus.
I’ve used the 0.2mm nozzle on a K2 plus.
Extrusion was good, but I’ve added a Phaetus extruder, so stock extruder may be different.
”adjust flow, pressure advance, or speed significantly” Oh yea. Definitely make and save a fresh calibration with that nozzle. Straight up calibration did the trick. No futzing after that for me.
”clogging, under-extrusion, or inconsistent layers” Layers and extrusion were good, but clogging is exacerbated by the smaller nozzle. Be careful if you use any “sparkle” or Wood, or granite filaments. Not all of the filaments have particles that will fit through a 0.2 nozzle. I used a sparkle from polymaker that they said was explicitly smooth enough for a 0.2 and it worked fine. Used a different one and clogged.
I also consistently clogged 0.02’s If I tried to use PLA after using PETG. Ended up keeping separate nozzles for each filament type.
It’s slower,but I never printed the same thing on 0.2 and 0.4, so I couldn’t say how much slower. Subjectively 2-3 times slower than as 0.4
With all that said, the finished print on a 0.2 nozzle is gorgeous!
