Weird extrusions (self.3dprinting)
submitted 3 weeks ago* (last edited 3 weeks ago) by lukstru to c/3dprinting
 

I just stopped a failing print and noticed some weird extrusions happening (not english native speaker, also I'm a 3d printing noob, don't know whether that's the right word). You can see it in the image. Any tips to improve printing quality?

I'm printing on an Ender 3 V3 SE. This print was with standard settings.

EDIT: as a clarification, this isn't why I stopped the print. It failed to adhere to the print plate at some spots. Redid my z offset and hopefully that solved it.

I was gonna say the z offset is too low, so the filament is getting squeezed around the nozzle and bunching up in those gobs. Did your adjustment work?

[–] lukstru 4 points 3 weeks ago (3 children)

Nope, this time nothing sticked at all. Washing with soap as a next step, as that helped last time I had sticking issues. Will try again tomorrow as it's getting late here.

Yeah, a warm soapy wash is definitely a good step to include here. Let us know how it comes out

[–] lukstru 1 points 3 weeks ago (1 children)

Yep, together with removing some junk from beneath the print bed and recalibrating that solved the adhesion problem.

Oh, good to hear!

[–] redbr64 1 points 3 weeks ago (1 children)

Also, how much are you adjusting, in terms of steps?

[–] lukstru 1 points 3 weeks ago (1 children)

I don't know what you mean by that :( what steps are you referring to?

[–] redbr64 1 points 2 weeks ago

Oh sorry, how many hundredths of millimeter are you are adjusting at a time. You should just make small adjustments and try them on a small first layer test print. But I guess you're live adjusting, so what I said doesn't make a lot of sense
