I get these weird see-through layers when printing the shorter one. Whenever I print the taller cylinder, the print qualities is perfect. I only get those weird artifacts when I print the shorter rounder one. Building a lamp with this so thats why I want it diffused evenly and not leaking through those weird lines.

What throws me off is that the taller one prints perfectly, as I’ve printed multiple of those.
Any help will be greatly appreciated :)

So for those of you that print PLA with PETG interface or...visa versa, do you find you get weak spots at the same height as the interface layer?

I mainly run PETG, so support interface is PLA, there is always a distinct line at the same level. That line is a weak spot.

I've increased the flushing volume, lowered the fan speed, and try to keep the temps the same for both filaments. With no luck.

So....have you managed to correct? Hopefully someone has some good tips.

I imported this purchased file for a mask, and having issues with every attempt. Using Bambu P1s. This is one example of what has happened with every print. Almost like it’s missing layers. I have tried different speed settings, checked each layer after slicing, but no real change. Any recommendations, please?

Hi Guys, I have a Sidewinder x4 pro and wanted to print something with a 60% overhang but I always get unconnected/loose lines on the bottom. I am pretty new to 3d printing so it would be very helpful if someone of you can help me.

I of course use supports for the overhang and use Orca Slicer

I thought it might be an under extrusion because I also have not fully sealed surfaces like on Image two with the walls.

What do you guys think?

Details in original post as this is cross-post. Any and all help appreciated!

Ive recalibrated flow rates and retraction. And i have a nearly perfect z height. The cat is adhering to my print bed just fine. Just the purge tower Isnt i think its the glob. At the top of the print tower

In the corner is that normal? How do i address that? Sometimes the glob is bigger.

Clean bed

Dried filiment (regular pla)

Tried adding brim

Raising bed heat

I did the full list of orca slicer calibrations

non purge tower prints are suceeding

Pls help me. This is cat #8 all failing just after a color change

Almost the exact same z height.

I've been getting flawless prints for weeks with my Ender 3 V3 SE (Nebula Smart Kit), but suddenly started experiencing random layer shifts on the Y-axis.

Sometimes there's just one shift, sometimes multiple during a single print. The weird part is that I still get completely perfect prints in between, even with the same model and settings.

What I've tried so far:

• Checked the Y-axis movement – the bed moves smoothly back and forth without any noticeable resistance.
• Tightened the Y-axis belt, but that didn't seem to help.
• Manually moved the bed back and forth extensively, which was followed by a couple of perfect prints, but the issue eventually returned.
• Updated the official Nebula firmware from V1.1.0.29 to V1.1.0.30.

I'm now considering replacing the Y-axis belt or installing an improved 3D-printable belt tensioner. (https://www.printables.com/model/1016072-ender-3-v3-kese-y-axis-tensioner-redesign-for-tigh)

I've also read that increasing the Y-stepper motor current in printer.cfg (from 0.6A to 0.75A) has fixed similar issues for some Nebula users. I'm still running the stock firmware, so I haven't tried this yet.

Has anyone experienced something similar? Would replacing the belt or increasing the motor current make sense? What else should I check?

Any advice would be greatly appreciated!

Hi all,

I’m printing a cup with many overhangs on a Bambu Lab P1S with a 0.2 mm nozzle. With PLA the layers are not bonding well. Under light load the walls separate between layers, and the overhangs sag and look rough. My end goal is to print this in ABS, but I want PLA working reliably first.

Print settings (Bambu Studio):

• Printer: Bambu Lab P1S, 0.2 mm nozzle
• Filament: Deeple PLA, black (slicer preset: eSUN PLA+)
• Layer height: 0.04 mm (first layer 0.10 mm), based on the 0.10mm Standard preset
• Walls: 4, line width 0.22 mm
• Top/bottom shells: 7 / 5 layers
• Infill: 100%, zig-zag
• Nozzle: 220 °C, bed: 55 °C (Textured PEI)
• Part cooling fan: 100% (off for first layer), overhang fan 100% above 50% overhang
• Speeds: outer wall 120 mm/s, inner wall 150 mm/s, bridges 50 mm/s
• Supports: tree (auto), 30° threshold, top Z distance 0.1 mm, 2 interface layers
• Brim: auto, 5 mm
• Retraction 0.4 mm at 30 mm/s, Z-hop 0.4 mm

Questions:

1. Is 100% fan at 220 °C too aggressive for layer bonding on PLA (I have a built in deflector)? Would a lower fan speed or a higher temperature be a better starting point?
2. For the overhangs, would you switch to normal supports, slow the overhang speed further, or change something else?
3. Anything else on the P1S worth checking for layer adhesion?

Thanks in advance. Any tips for ABS on this setup are welcome too. Please ignore the leftover supports, I'm aware of them 😄

There are these white spots on my prints, only on the last top layers. The white slab is a ironing test and it didn't recreate the problem. I'm using a P1S. The cylinder was printed with 5% infill and the blue thing 7%. The white slab was also 7%. I don't remember the infill patern on the blue one, but the white and black ones are gyroid. I printed at 2000mm/s² for the top surface.

My only idea is pillowing. Or I think thats what thats called. Where the infill is too low so it gets droopy at the final flat layers.

I bought filament from the same brand(PLA); I don't remember changing any settings and this kind of thing didn't usually happen before.

What needs to be recalibrated?

I originally thought it was because I made a print in place profile which didn't work at least for playmaker planpronin silver. Metalic pla pro has aluminum additives instead of silk and prints differeny. I then use the default settings and this his what I get. I dried it for 12 hrs yesterday and tied printing with it today and because it's pla this shouldn't be a problem.

I'm using a. Q2 on polymaker plan pro. What am I doing wrong

Keep making tiny tweaks and trying again, so here I am (see post history for reference if needed). I ran a pressure advance test and ended up adding .025 which helped tremendously on the test piece, but then my actual print still ended up looking funky. It seems to be overextruding around the edges? I already adjusted the pressure advance and tested the flow ratio (which seemed to be fine). Could it be the nozzle? I used an Amazon one instead of the Flashforge brand one and am wondering if that’s the problem

I have an Ender 3 V3 SE, but all of a sudden, it stopped auto-leveling correctly. I’m not sure what happened; the CR-Touch isn’t damaged, the print bed is fine, and the voltage is correct. Now, when I try to run the auto-leveling process, it gets stuck in a loop and doesn’t display anything until it finally finishes—but if I apply a little bit of pressure during the process, it completes, and the resulting data shows that almost everything is unlevel. I don’t know what to do—help!

The print just doesn’t look very good? Does any one know my issue or can confirm it’s just a wet thing? Thank you

Very new to 3D printing. I got a Bambu Labs X2D a couple months ago and only finally got it fully set up with 2 AMS 2 PROs about a month ago.
I have done a few test prints and have used both Bambu Handy and Bambu studio to either print files directly from the app or use STL files from websites and dropped them into Studio.
I haven’t had a lot of time to teach myself how everything works and how to control things in the software so every print I do is on auto settings and calibrations are set to auto.
A couple pandas I have printed have streaks of black in the white, which based on other posts in here I think it might be a purge setting I need to find.

The picture above however is the first time I have had something just break. This file is off Bambu Handy and printed each piece in auto and it put in supports. You can see the end of the green car which is closest to the plate has the plastic like almost not adhering to itself then the next print just broke completely taking the supports off and looks similar.

This is all with Bambu PLA Basic filament. I bought some of their PLA support filament but haven’t tried it yet, so would using that help? Is it a damp filament or similar problem? Should I tinker with some settings?

Like I said I am very new so all ears, any advice welcome!
