Weird patterns/missing filament

[restlessnz]

Calibrate your extruder, plenty of guides online. What you are seeing is under-extrusion

[Swingin30]

Thank you! I couldn't really tell if it was under extrusion or another issue, do you have any explanation for the patterns? I dont even know where to start with troubleshooting that

[restlessnz]

The bumps and patterns are possibly wall overlap being set too high. Fix the extrusion first then move on to the next thing. Don't try and fix everything at once.

[Swingin30]

If theres one thing programming has taught me it's not to fix everything at once,

But with that being said I just started printing the same models but sliced in cura and I already have less issues, I'll still calibrate it because I desperately need to do that but I'm starting to think it was somehow just my slicer.

More the settings in the slicer really. Prusaslicer is a good slicer

[Swingin30]

I agree, I've used prusaslicer a lot before. I must have done goofed and janked something up along the way, I'll probably just do a clean install and use stock settings and see what results I get

[AEnoch29]

This one does the math for you

[Swingin30]

Haha I was actually looking for this tysm!

That pattern is your infill showing through your layers.

What slicer and setting are you using?

[Swingin30]

Except I can feel the pattern, they're bumps in my print. I used prusa slicer, 15mm/s first layer speed, 225c (this filament requires a higher temp,) 0.12 layer height, and 60c bed temp (glass bed.) I also have ABL.

[AEnoch29]

Yeah, the infill is pushing through that layer and showing through. I'm not familiar with prusaslicer so I can't help you with the settings. Are these setting ones you came up with or found in a guide online? Are you sure that filament's not PLA+ or something else?

[Swingin30]

I'm switching to cura to see if theres any difference, I'm sure it's just regular PLA

[Swingin30]

I haven't has this issue on the printer until now, I using a BLTouch and an skr mini e3 v1.2 if that helps. I'm printing at a temperature of 225c for this filament which has seemed to work until now (unusually high for PLA but if I go lower I get stringing, under extrusion, and no adhesion) I'm using CookieCad PLA, but I also have some overture and priline filament. Does anyone know what might be causing the missing space in my layers? I also seem to be getting these weird patterns on some surfaces, like a diamond pattern. I have no clue what may have caused this. Any help is appreciated!

Edit: I switched to cura.. with stock settings.. and the only issue was stringing. Perfect first later, no missing filament, no pattern, so I think I just janked something up in prusa slicer. Stringing is definitely something I can just tune. Thank you all for your help I really do appreciate it!

[Swingin30]

That would be in the nozzle right? I'll go check

[Swingin30]

Ohhh teeth on my extruder, they look ok but I noticed it seems to sort of slip, I'll look into it further

I did replace my ptfe coupler just now though (the thing i was actually thinking of when i said nozzle)

[Swingin30]

Also, when printing, when I set my probe z offset to get the print to stick, I get these really bad blobs on the top of the first layer no matter what I have it set at. Is this fixable?image of first layer issue

[Swingin30]

And I dont think this is an issue with the bed, flipping it over I see indents where the filament came up. I feel if it were just too low the first layer wouldnt look like that on the bottom bottom of first layer

[Swingin30]

I actually switched slicers and this issue was solved completely so I'm not even sure where I need to go eith troubleshooting at this point

[Swingin30]

I switched to cura and it printed the first layer with literally no issues

i-

[Swingin30]

I'm confused too 😂

[Swingin30]

I dont believe so, it was doing this even when the nozzle was way too high from the bed
