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.
It's either over extruding or a bed level issue. First level bed again and if it still happening calibrate your extrusion flow. Since you had adhesion issue, probably just bed leveling will solve issue. If bed is well leveled and still have adhesion issue, clean your bed with basic soap and hot water (and avoid touching bed with your hand as much as possible)
If you haven't yet, I recommend following some calibration guides for your filament brand / style / nozzle. I've been using https://github.com/SoftFever/OrcaSlicer/wiki/Calibration in conjunction with the Orca Slicer software, though I know that's a derivative of Bambu software and may not directly translate to your Ender. But something along those lines should help to at least make sure you're working from a proper baseline.
Just installed Orca Slicer and did the calibration run. Very interesting results.
I flipped them over in their respective positions, i.e. -5 is still in the middle right.
What I interpret from those pictures is that I need different values for the first layers and the layers above that. For the top layers, -5 and -10 look very good, for the first layer +10 and +15 are looking good.
And yes, I know my printbed is kinda fucked, I already ordered a new one. Surprisingly, it didn't impact performance that much. In the last weeks, I had no failing prints whatsoever with the standard settings. Sure they weren't looking pristine, but usually that didn't matter.
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?
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
Yep, together with removing some junk from beneath the print bed and recalibrating that solved the adhesion problem.
Oh, good to hear!
Also, how much are you adjusting, in terms of steps?
I don't know what you mean by that :( what steps are you referring to?
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
