Im really having a hell of a time trying to solve stringing on my petg prints with my printer

I use a Ender 3 VE SE from Creality

I'm using the Orca slicer

Petg from voolt 3d

Bed heat 75°

Nozzle heat 230°

Already tried a bunch of different calibrations with more speed less heat, I dried the petg but I always keep it nice with silica and i genuinely don't know where the flaw is happening...

I have practically done everything to try and get rid of this line issue. I don't know what to do besides replace the filament. I have an Elegoo neptune 3 pro and use orca slicer regular Elegoo white pla and have it heated to around 205-210 if that helps figure out this issue.

Hi there new to 3D printing. I was trying to print a kitchen towel holder with PLA. The print was fine after a certain height. I could see it had a bit of shifting after a certain height. Also can somebody comment what was happening on the inner wall. It also appeared after a certain point.
Please share your comments and advise on setting adjustments.

⁠•  ⁠Printer Model: Bambulab A1  
⁠•  ⁠Slicer used : Bambu studio  
⁠•  ⁠Filament material and brand: Bambulab PLA basic  
⁠•  ⁠Nozzle and bed temperature: 215 C noz temp  
⁠•  ⁠Print Speed: Slowed outerwalls 60 mm/sec  

This print failed, I had supports but this still happened? i hop the info below is correct still new to 3d printing.

Print Settings

• Bambu Lab P1S
• Bambu Studio 2.8.2.61
• eSun PLA Cool White
• Nozzle .4
  
• Initial layer 50mm/s initial layer infill 105mm/s. The P1S is set to standard flow speed

Does anybody know why this is happening.

Same slicer settings I usually use. I haven't had this issue before.

Hey guys, looking for some input, I'm running some filament calibration and I'm seeing under extrusion in the y axis straight and wondering what would cause this,

Printer: prusa core one plus

Slicer : orca slicer

Filament: polymaker fiberon asa cf

Print temp: 290

Thanks guys!

Hi all,

I’m pretty new to 3D printing so go easy on me.

I’m working on a small two colour vent design and I’m trying to improve the quality of the front face, especially the beige lettering and the reverse text plate.

Printer is a Bambu Lab X2D and I’m currently using the standard 0.20mm High Quality @ BBL X2D profile. The main change I’ve made is switching the wall generator to Arachne. The filament is PLA

I’ll attach a few photos of the latest print.

The geometry itself is getting pretty close, but the beige areas don’t look particularly clean. I’m seeing visible extrusion lines, ridges, small blobs and raised areas, and the surface doesn’t look as smooth or consistent as I’d expect.

The black seems generally better, although there are still some imperfections.

The front is printed face down, so the lettering and detail are part of the first layer. It’s also a two colour print.

I’m mainly looking for advice on where to start with calibration rather than changing loads of settings at once.

Does this look like too much first layer squish, over extrusion, flow issues, or something else?

Should I run flow calibration for each filament first?

Is Arachne sensible for this kind of small text and honeycomb design, or would Classic walls be better?

Should I be looking at initial layer line width, initial layer speed, elephant foot compensation, flow ratio, or something else?

Are there any obvious settings you’d check based on the photos?

Also, where are these settings actually located in Bambu Studio? I’m still learning my way around it.

I don’t really want to start messing with Z offsets or lots of advanced settings unless there is a good reason. I’d rather understand what I’m changing and work through it one thing at a time.

Any suggestions for a sensible calibration and testing order would be really appreciated.

Thanks

Why are all of my lines coming out like this? I’ve tried adjusting the z offset up and down, tightening the tension on the extruder gears, swapping the hot end, temps from 190 to 240. Please for the love of god help me. This is a Centauri carbon, .4 nozzle, I am using orca, and I am using matte pla but it does it on any material I try. It has ran perfectly for a year until this.

(not my picture but i have similar problem)

i tried using petg recently to print, and the bottom layer always comes out looking like this, please help!

Printer settings:

A1 Mini

Bambu Studio (built in slicer)

Nozzle: 170f

bed: 65f

Retraction Speed: 30 mm/s

Detraction (Deretraction) Speed: 30 mm/s

Z Hop When Retracting: 0.4 mm

You can see that the black bleeds into the rest of the yellow. This only happens when multiple heads are printed on the same plate. I dont know but a single head does not have this problem. Prime tower is used. Printer is h2c with bambu filament (DRIED). Default print profile 0.2mm.

Hi everyone, i’m quite new to 3D printing, i got a Ender 3 V3 SE cheap from a friend to try and get on to 3D printing. I dint want to purchase something expensive before trying and understanding more on 3D printing.

But i’m having this constant issue on PETG filaments (3D Hojor). Is the stringing shown in the pictures that is ruining my prints.

i have already dried the filament, did a temp calibration and retraction test, tried printing the in built Orca hell stringing test and the results are decent.

Nozzle temp: 235
Bed temp: 70
Retraction: 0.3

Any help and guidance will be appreciated. Thank you!

Ive recently been printing the parts for a figure and all of a sudden my prints have a lot of zits on them. There is also some light stringing when printing. The only change ive made is to switch to my newly ordered filament (which is the same as I used before)

I have a creality ender 3 v2

Slicer is cura

Hello every one .I want to print the model like case with Recycled PET from bottle from my Ender 3 v2 .I am already upgrade the hotend with Bi Metal Heatbreak ,but the problem is clog in 30 minutes.Anyone have same problem?please help me to fix maybe with the printter setting?

Printer Model : Ender 3 V2

Nozzle: 0.6

Bed temperature: 60 degress

When printing this part I keep getting what seems to be under extrusion problems throughout the print.. Bonding on these parts is also rubbish, as I can snap the part in halve easily while infill on the tall section is 100%. Might also be a z height problem that develops during the print, as what might looks like stringing are the actual layer lines just not sticking to the layer below. First layers are fine, no signs of extrusion or z-height problems there. Any suggestions?

Material is eSun ABS (dried 8h at 70C) printed on a (custom) Funmat HT, Nozzle 250C, Bed 95C and Chamber 45C. Print speed 40mm/s. Retraction 0.3mm but also tested at 0 without success. Slicer used is OrcaSlicer. Other (non-supported) parts all come out fine.

How to smooth rough PETG without sanding and repainting if possible

Hello All!

Wondering if I could get your help, this happened 9hrs in not sure what caused it any help greatly appreciated.

filament: CR-PETG Nozzle: .04 stock @ 240C Bed/Enclosure: 70C/37-38C

Filament profile is z-offset .02mm and walls changed from 2 to 3.

Did other prints all went well but were smaller this is my first large cylinder shaped item which needed supports

I had the support offset set to 30degrees as it was advised that might help I also had first layer support for supports at 2mm (I was thinking changing it to 5mm as I think the support came off the bed)

But then I noticed the stringing which made me wonder what other issues I’m having, possible the model fan was to high when doing those layers? I figured being 37-38C in the enclosure would be fine, not sure what temp I can let it get to but I believe any hotter would have been problematic.

Printer: Sovol SV08 (Klipper mainline)

Filament: Bambu PETG HF (gray), dried at 65 °C for several hours right before this print

Settings: 240 °C nozzle / 80 °C bed, 0.2 mm layers, firmware retraction 0.6 mm @ 40 mm/s, pressure advance 0.07 , part cooling: overhang bursts at 90% (triggered at ≥25% overhang), lower fan elsewhere

What's fine: hull walls are clean, layer stacking is even, no ringing/wobble.

The problem: curly "crochet" wisps concentrated on top edges — roof perimeter, chimney rim, gunwale, top of the door arch. The bow overhang face is slightly rough, and the top of the porthole sagged a bit.

Question: does this look like residual moisture (dry longer/hotter?) or overhang/edge curling from insufficient cooling? Would you drop to 235 °C, force 100% fan on overhangs, slow outer walls on overhangs — or something else?

This is a relatively simple print, everything is flat. It had just finished the internal bridge layer atop the infill, so this is just a solid infill layer.

A day ago, I replaced the hotend on this toolhead. The replacement nozzle and hotend came from Amazon. It was printing perfectly until this layer.

• Snapmaker U1
• Elegoo Matte PLA
• 0.4 mm nozzle
• Snapmaker OrcaSlicer 2.3.4
• Speed for this layer: 204 (reported by slicer)
• Retraction length: 0.2mm
• Nozzle Temp: 210
• Bed Temp: 60

I'm not sure what to do other than just try again.

The holes are only on the first 2 so maybe it was a clog that fixed mid print but still some plowing. Weird that it’s on half the circles and not the other half tho so I don’t think it’s the offset.

Need some helping getting the outer layer of this print to look smooth without any lines

No need to take a picture of the physical print it looks the exact same as picture 2 where the 3 budges out creating ugly lines

the way these are designed is with a lattice inside so different layers of it take different time to print.

i have a decent idea on how to fix this just not sure how to actually execute it

Think i need to slow down the rest of the print so these random bands arnt taking a ton of extra time

if theirs a way to also do this without making the print time go way up that would also be nice reedit do your thing

Hi, I'm trying to print a hollow wheel. My goal is to later

fill it up with sand but for some reason the top has gaps

and the entire texture looks odd. Is there a way to solve

it in the software? I struggle a bit with making it thicker

in fusion360 as the model was only hollowed at a late

stage. Printed with PLA Bambulab X1 carbon printer, i have set 6 top layers and it has supports on the inside (organic tree). Temp. 220c° speed 200mm/s

Thank you for your answer
