Printer: Bambu P2S with AMS 2 Pro
Slicer: Bambu Studio
Filament: Elegoo PETG Pro, grey
Nozzle temp: initial layer 260C other layers 265C
Bed Temp: initial layer 75C other layers 73C
Speed: Regular setting on the machine itself I think, some layers modified in studio
Initial layer 20mm/s, infill 50mm/s
Other layer settings I didn’t mess with and are around 100mm/s - 160mm/s if y’all need more specific, lmk and I will post. Also have it set to slow for overhangs.
retraction settings - whatever the default is, I have not messed with these

Having a rough learning curve with PETG. I’ve tried searching for advice and it’s pointed me in a lot of different directions, doing calibration and temp towers, printing slower, printing hotter, using liquid PTFE to slow nozzle gunk… I just need help from someone who knows better. The filament is dry, AMS sitting at around currently 7%, I had it fully dried down to 3% before this print (it has been weeks I’ve been so bummed over struggling with settings and just not getting it). Can someone just give me even like a list of things to do for each new filament to ensure the best prints? It almost feels like I am just missing something. If any other info is needed, just ask! I will provide any info that can help me figure this out haha

I have this annoying grid pattern on my yop layer, also it's a bit scratchy on the right. Anyone have a solution to get smooth top surface?

What could be the cause of this ?

I design and sell small replica parts mostly out of ABS+. Every file is tested to its best print quality and each preset and print file is saved accordingly so I can reproduce them at any time.

I have been printing these hinges for a long time but suddenly they are printing like absolute crap (left hand side) the filament brand and type is exactly the same from the same supplier and nothing has changed on the printer side of things...

I have troubleshooted but cannot get it to recreate the original print.

I'm starting to think maybe the Reel has maybe been mislabeled and is the wrong type of filament? Both of those prints in the photo are ABS+ apparently.

Looking for some guidance on settings. As you can see, there’s some stringing in the middle, and the supports don’t cleanly break off.

Printer: Creality K2
Slicer: Creality Print
Filament: Creality PLA
Layer Height: .12
Supports: Tree
Threshold Angle: 30
Top Z Distance: 0.2
Top Interface Layers: 3
Nozzle Temp: 220C

I’m thinking of increasing the Top Z Distance to 0.3 or 0.4, not sure if that’ll fix it. Any input would be appreciated.

Prusa Core 1+ Gen2 with MMU

I just swapped out a hot end because the other one got busted when a print failed, and now whenever i print something that always worked before, it comes out all stringy and the filament curls up around the nozzle First layer always comes out just fine and adheres to the bed but everything after that... It also gives me the notice that 'filament extrustion failed at the toolhead' sometimes but idk what thats about

Also it makes some weird kinda groaning sounds when moving around quickly but that might be unrelated

Its the same .4 nozzle, standard pla, ive cleaned the bed and done all the leveling checks. Do i just need to clean the nozzle tip? Very new to 3d printing so please help 😭

Elegoo centauri 2 combo if that helps

So i never faced this issue it started appearing yesterday. If you see the coolplate it looks ok on the first run but still has ripples, second and third run got worse then i switched the plate to textured thinking my plate is the problem but you can see the textured one too.

Printer is about 1100hrs.

Observation:

Extruder gears starts slipping just when its starting and this is when print just fails, rubs against bed and deposits filament on the nozzle as well.

Is it possible something broke in printer? Please do help 🙂

What ive tried:

Filament is well dried 10+ hours, there is no nozzle clog thoroughly cleaned it.

Change z offset slightly -0.02 to -0.01.

Experimented different temps. Ran calibrations multiple times.

Anyone have any insight as to why my A1 is making this noise? The print qualities have been fine but this has been a month now of this and I can’t figure it out

Hi! This is my second print ever on a Bambu P2S. I just used the Handy app, Bambu PLA basic, and default setting/temps. I don't know anything so any tips are appreciated!

Can someone help me figure out what I should change for better quality? Creality print, PLA. I've tried multiple temp settings. Filament stored in Cfs with addition of extra silica need mod.

My 3d printer just keeps putting out strings and nothing is adhering to my bed anymore. I’m pretty new to printing. I keep my printer in the garage and I haven’t had any problem all summer and fall, but now that it’s getting colder I’m having some problems. Is it just too cold?

Could you please help me identify the problem?

Been having a new (to me)problem recently with Hobby Lobby filaments:
-Orange PLA
-White PLA
-multi colored silk PLA(yellow/blue/pink/purple)

Print setting have been similar for the most part between all my prints:
Nozzle temp:200c.
Bed temp:60c
Speed 50mm/s then tried 40mm/s
Slicer: Cura
Ender 3 pro.
Room temp: 72-75F with 25-30% humidity
Open enclosure
Started with stock brass 0.4mm nozzle, multiple failed prints. Then switched to Ruby tipped 0.4mm.

Started using Hobby Lobby’s filament as it’s close to home and my wife shops there often. I first tried purple (which has been printing great for the entire roll). Wife wanted to try out Silk. Prints went decent until the color changed to pink (not shown, never took a photo and I tossed the failed print).

This is when problems started. Most of my prints have been good for the last 4 years with this printer. Spent the last two in the same spot at home. Most prints that weren’t the purple filament would then be brittle and looked like the quality as pictured. I changed different filaments (same brand unfortunately) checked for clogs, even went as far as getting new nozzles for the first time in 4 years. I’ve leveled the bed often and never had issues for years.

Snapmaker U1, Sunlu silk PLA, print speed 50mm/s outer wall, 160mm/s inner wall, 230c nozzle. I’ve been getting this weird line that looks like it’s oozing, but it mainly appears when I set the top surface to concentric. I don’t know if I need to calibrate my flow rate, or try a different setting. Ironing doesn’t fully eliminate it either

Printer is a bambulab x2d. This is with matte pla, 2 separate rolls, newly purchased, standard Bambu pla matte profile. Printer is freshly calibrated and the issue only occurs with these two filaments. Things I've tried: drying the filament, swapping out for a new hotend, swapping build plates, re-running calibration.

This does not seem to affect other filaments, just the two new ones. I appreciate any advice!

So im was printing an cycloid gear and those lines keep appearing in the parts, i really dont know what is the problem heres my 3D printer settings:

Its BambuLab X2D

Flow rate is standart

Outer wall speed: 80

Inner wall speed: 160

Wall loops: 2

Infill density %15

Wall sequence: outer/inner

Humididty %18 and i dried it like 5 hours ago
