<![CDATA[Anyone interested in helping me troubleshoot an issue with my 3D printer?]]>Anyone interested in helping me troubleshoot an issue with my 3D printer? When printing on my prusa core one with one of the default speed profiles, I’m getting this weird, inconsistent extrusion pattern.

I don’t think it’s one of the following:
- too high print speed (130mm/s)
- wrong extrusion multiplier (previously calibrated)
- nozzle clog

Any ideas?

I always assumed it to be some combination of speed and nozzle temperature (because it looks like the nozzle drags a tiny bit of material from the lower layer into the direction it moves before it immediately hardens again), unfortunately never looked into it further.

If you already calibrated the multiplier and there aren't artifacts on the slope (doesn't look like it) I suspect speed and temps. 🙂

that looks like humid wet filament issue

(I'm not an expert)
