Users are experiencing issues with their 3D printers, including inconsistent extrusion, stringing, and texture problems. These issues often arise when switching filaments or after printer upgrades, leading to failed prints and frustration.

Once the nozzle starts moving, the filament seems to lay down fine, but the initial bit doesn’t stick properly and leaves a small raised section. It seems to happen consistently at the start of each new extrusion rather than across the whole print. I’m using a Bambu Lab P2S. Has anyone experienced this before?

“I don't know what's going on I can't get this printer to work right, I didn't have any issues until last month. Now I can't print anything. Ad5m pro. Smooth plate. Pla. Default settings. Bed at 220 head at 55. Using magigoo adhesive. 608 bearing printer free spin roller. Tension screw adjusted properly. Even tried changing the gears. I'm losing my mind. submitted by /u/ManiacalMay [link] [comments]”
“My prints started having this bulged section with really inconsistent extrusion at the bottom of the print. The prints also came out 2mm short in the z direction. I tried cleaning and lubricating the z-rod to no success. There is also some minor under-extrusion somewhere else on the print so could it be a nozzle issue? I'm printing PLA on an SV06 Ace. submitted by /u/Thompson_Studios [link] [comments]”
“This issue just started out of no where. Looks like overextrusion maybe? Issues with the z -axis one way or another. This is about as far as it gets before the nozzle pushes it off. Im printing pla on an ADX5 flashforge, right out of a dryer with like 20% humidity atm. Any help is greatly appreciated. submitted by /u/gkibbe [link] [comments]”
“P2S, 0.4 Tungsten HF, PLA Green Mate Sunlu. Hey guys. Someone know why I am getting this weird texture with just this Sunlu PLA? I printed varios other plates with other mate PLA (Elegoo) and didn’t get this texture submitted by /u/Leading_Tradition471 [link] [comments]”
“The Nozzle is heating up properly, and it's cleared out, so there's no clogging inside of it. However as you can see, the filament doesn't go past the markings, and no filament comes out from the nozzle head. I cleaned the extruder properly, this issue was a pre-existing one from the previous owner of the printer. I once managed to get it running, but now it's stuck once again. What could be the solution for this issue? submitted by /u/Tnemmokon [link] [comments”
“Hi everyone, I’m printing with TPU 95A. The print starts normally, but after some time the filament suddenly stops extruding while the printer keeps moving and following the toolpath. I tried unloading the filament, cutting off about 50 cm, and reloading it, and the next print went further than before. Could this be caused by the filament itself, extruder/feed issue, nozzle clog, heat creep, or even bed leveling? Any ideas what I should check first? submitted by /u/EnvironmentalAd183”
“Hello I am printing a project I have printed many times before including with this sunlu pla filament but this time when I do it the printer is leaving large holes in the print I have tried leveling the printer and it hasn’t helped it is only this filament what am I doing wrong? submitted by /u/ThaneJackson03 [link] [comments]”
“This is the benchy model that comes on the USB stick with the CC2. I had the same issue with the included PLA and this is Elegoo PLA. Other than this, the print is pretty flawless and I’ve had no issues with any other prints. It’s possible it’s an issue with the file, but it’d be pretty silly if Elegoo included a dodgy file with the printer. I’d just like to get ahead of it so that if it’s going to affect an important or big print, I can check settings and avoid it happening. Thanks! submi”

“I am beside myself with this filament. Overture Matte Light Grey and Black. Top surfaces and infill are terrible but perimeter looks fine. I have done the cold pulls to eliminate partial clogs, slowed down to 50% print speed, increased temp, decreased temp, tightened nozzle and extruder gear spring... it seems to print fine on my Prusa MINI but on my Neptune it is being a right pain! submitted by /u/TheLastKell [link] [comments]”

“Hi all, I've been trying to print lithophanes, but i am running into this issue at specific regions. It looks somewhat like underextrusions or something even though I recently calibrated my extrusion multiplier and it looks good everywhere else. I even tried to print only the affected section and it still showed up defective. I am using PLA +, worth noting that in general I never encountered a problem with this brand of filament. I tried changing temp (180-220), changing speed (30-120), chan”
“I'd "love" it if someone had an idea of what I’m doing wrong here... ;) The thin-walled heart shell that I’m printing goes bad at the outer (slightly thicker) edges of the print, about where the “internal infill” starts getting replaced with “Solid Infill” near the edges of the shell as the shell goes upward (referencing the PrusaSlicer’s internal view) (See also the slicer movie here ( https://youtu.be/C2ZHjdbNaKc)). The shell is actually thicker on the sides, which is why the ext”
“Hi everyone, I’m hoping someone can help me solve a recurring print-quality problem. Whenever I print parts with many small holes like the one in the photo, the top surface comes out very rough and messy.

“recently I tried to print a paint rack. halfway through, the printer decided it wanted to make a tennis ball sized blob instead. every time I try to print something now, it seems to leak filament from the base of the nozzle (as seen in video). just wanted to know if this is a common issue or if there is an easy fix for it. any help would be greatly appreciated. printer is an elegoo neptune 4, just using standard black PLA, temps between 180° and 220°. problem only occurs when printing anything,”

“Every print that I make, any filament I use, it always has the same result. The bottom few layers are completely fine, then 5mm are complete trash and the rest of the print is again completely fine. The bed is leveled, the filament is dry, the printer is clean and stock, the nozzle is in top shape... Could this be like a spec of dust trapped somewhere on the Z axis? Should I take apart the printer and clean it properly? I own it for 3 years and this issue was there since I remember. It's an”
“I got multiple print and object’s on the same printer that all got this line at a certain Y value. It looks like the exterior wall that is under-extruded. Anyone else got this issue?

“My A1 is severely under-extruding during prints. Manual extrusion works fine, but during printing the extruder sometimes makes a repeated “click click click” sound and the filament stops feeding properly.

“I keep getting blobs forming on my print nozzle. I’m using PLA at 195 deg C. Printer is an Anycubic Kobra 2 Neo. Any ideas on why this is happening? I just replaced the nozzle, because the old one was clogged. It looks like filament is leaking around the top of the nozzle. Did I not screw the nozzle in tight enough? I’m pretty new to printing, I don’t know much beyond the basics. Troubleshooting is still a challenge. Thanks for the help. submitted by /u/SterlingArcher32 [link]”
“The print serves it's function perfectly well, so there is no reason to throw it away, but I would like to know what to do different next time. The filament is tpu 90a and the printer is a bambu p1s. The filament was fed directly into the printer as opposed to being fed through the ams. The filament was left out for a year (around 50% humidity.) before it was given to me (free roll). I dried it in my space pi drier at the appropriate setting for 12 hours before I used it.

“On some prints, even on ones from the app that normally work, the extruder will click similarly to when it’s clogged and unable to push filament through (the wheel will click and move back and forth).

“I'm using a Anycubic Kobra S1 with the ACE combo attachment. The filament is Overture PLA. I've used this spool to print other items without issue. I went about a month without printing anything. Before I started printing, I ran the drying cycle on the ACE for 2 hours. In the picture , you can see the smooth surface is interrupted by jagged peaks. The front right portion of the print is very smooth. The rest of the print is very rough. What could cause this? I thought it was a case of we”

“Hi all! Looking for some guidance :). At certain angles the print shows these ugly lines, or maybe that's normal? At other light angles the ugly lines reduce a lot. I'm referring to what looks like an uneven texture of lines. I did temp, flow rate, pressure advance, and max flowrate calibrations. Should I give up and accept this as a normal print, or is there more I can do in the slicer? submitted by /u/Ok-Broccoli5316 [link] [comments]”
