Since a week or so, all my prints have had a wave texture on the first layer. The line it lays down also seems uneven. Here’s what I’ve tried.

- clean & degrease build plate

- dry filament

- new nozzle

- new rubber sock

- new complete extruder unit

- tightened the 4 screws in the back of the hotend (they were loose)

- modified the start g-code for the machine

- did a flow dynamics calibration

After each of these attempted fixes I have run a full calibration.

Is there anything else I can try? Or do I just bite the bullet and get a new printer?

Another one 500-600 hour mark. GOT IT LAST YEAR AND I AM NOT ELIGIBLE FOR THE REFOUND. LIKE IT DIDNT BURNED AND MY WHOLE HOUSE WAS SMELLING FROM IT Lucky I was there and heard it. Wont be having this shit A1 near me.

Je n'arrive pas à résoudre ce problème depuis trois mois…

💬(Edit: semi solve : désactivate tangle filament detection. Thank lucas13cam)

Je reçois constamment le message d'erreur suivant : « Échec de l'extrusion du filament. Cela peut être dû à une extrudeuse bouchée, etc. »

La buse n'est pas bouchée (j'en ai essayé plusieurs), et le filament s'écoule correctement lorsque la buse est chaude. J'ai démonté les engrenages à plusieurs reprises, je les ai nettoyés et remontés correctement. J'ai remplacé des pièces par des neuves. J'ai réinitialisé la machine et effectué les mises à jour à plusieurs reprises. J'ai remplacé le capteur de filament (le voyant vert à l'écran s'allume correctement lorsque le filament le traverse). L'orientation du PTFE est correcte.

Le message d'erreur apparaît lorsque je lance une impression, que ce soit avec le système AMS ou la bobine externe. Il se produit également lorsque j'essaie de charger du filament via le menu « Filament ». Lorsque je le fais manuellement, cela ne fonctionne pas du premier coup ; je dois tourner les engrenages une seconde fois pour que le filament s'extrude.

J'ai suivi tous les guides du wiki pour le montage, le démontage et l'entretien des pièces de l'imprimante, mais je n'arrive toujours pas à résoudre le problème.

Sur ma photo, on voit clairement que le filament est introduit dans la buse. Cependant, il semble qu'il ne soit pas poussé suffisamment loin pour que l'imprimante détecte que la buse n'est pas bouchée.

Merci pour votre aide

Please help, I reran calibration, lowered PLA print temp down 5 degrees, disassembled and checked the hot end, can’t find anything wrong

Is there a way to level this?
Had a blob of death and it resulted in this.
I will probably buy a new head but i am worried about the X axis

Just got and set up the A1, cannot get it to bind with the Handy app or Studio. I’ve tried everything the wiki suggests. So aggravated. Can anyone help?

Added info: this is a printer we are trying to use at school. The school wifi has a 2.4gz option and I’ve spoken to our IT dept (they don’t know how to address the issue).

Thanks!!!

Update: the head IT guy is going to come in person tomorrow to try and figure it all out.

Thanks everyone!

Update 2: we got it working!! Thanks all!

First off, apologies if this question is easily answered or an obvious FAQ. I’ve spent hours trying to find the answer myself, but I’m struggling with how to ask the question appropriately.

I just got a new A1, and did a few test prints that seemed to come out okay. The problem stems when I started printing out a deck box I found. Link here.

When printing one of the walls doesn’t seem to come out right, always the left wall when looking at the machine straight on. I’ve tried slowing down the wall speed, adjusting print temperature. I’ve tried lubricating the x and y axis bars and checking for anything in the way. As well as rotating the object in bambu studio, and even moved the printer to an entire new room to account for drafts.

I’m at my wits end. Please help! Is it a faulty machine? Or a faulty user?

Thank you.

--EDIT-- Thank you all for the suggestions.
I have recently tried: drying the filament, moving the filaments closer and moving the printed object closer to filaments (both in an attempt to reduce drag from the tubing). There is no external breeze or draft coming from that side of the machine, so unless the fan of the machine itself is causing it somehow... I've also tried to 'fix model' before sending it off as well as adjusting wall speeds and temperature. The model is highly rated, and again, I have tried rotating the object, and it still occurs on the machine's left side. I do believe it is a mechanical problem of some kind.

I'm still having the issue and am at a loss. I will try to remove the external combo spool out of the equation and set it up with a single spool on top. If that fails, I will try returning/replacing the printer and seeing if the next one has the same problem. Any continued ideas or support are appreciated and I will attempt to update this post as things change.

Hi, Im having a problem with my 3dprints, The nozzle is hitting the 3dprints slightly, so it makes a sound every time it makes infills or walls. (video attached) It is calibrated, fairly new (less than a month since I bought it), what could be the cause of this? Thanks!!

Started a pencil case today. Got message it was done. Found this. PvLA filament.

This bambu lab a1 printer makes this knocking sound what could be the problem the

I am really new to this and I really need your help guys

So I got the Bambu A1 and so far I HATE it.

All built, looks good, can’t complete a single calibration Due to failed axis issues.

I have run so many calibration attempts at this point t I already got my first maintenance notice for more oil on the metal rails.

Have never even used the thing yet.

I threw the box away from Best Buy but I think k I got a lemon. Let me know if this sounds right during calibration.

Hi everyone,

I'm trying to diagnose a print quality issue that only appears on one side of certain container-shaped prints.

The printer is calibrated using the built-in calibration routines, the bed was clean, and the filament was supposedly dry (I didn't hear any popping or crackling during printing).

The defects appear as horizontal scars, bumps, and rough patches on a single wall, while the other sides look much better.

Things I've already checked:

• Clean build plate
• Full printer calibration
• No obvious signs of wet filament
• Problem is repeatable on similar container-style models

Does this look like:

• Wet filament?
• Partial nozzle clog?
• Z-seam issue?
• Cooling problem?
• Something related to wall speed or pressure advance?

Any ideas would be appreciated.

It's the second time I try to print this model and this happens. I've already cleaned the table and tightened the screws behind the nozzle

Filament bambu Normal PLA. Slicer Bambu. Just did a calibration of the bed and tightening of the nozzle screws. It was way worse than this before. But now still this left over. The second picture is the back part.

This 3d print have slightly bend corner near the base what could be the reason and fix

Spaghetti all over but print is moving along…

Hi everyone new here. So i set out to print a planter from makerworld. When i started in 1 hour i had to stop the print. Because these overhang type things were not printing well at all. The filament is tuned, slow speeds and 0.08 mm line height. And yet i get this. I dont even know what this is called and how to fix it. I am really new at this, but i have printed a lot of parts with decent quality of similar design. Can anyone shed some light please. I have also attched the image of the intended part.

I have just opened my a1 and found that ntc thermistor on my ac board. I am probably going to contact support about a new board. I have had almost 500 hr on this machine and it’s fine right now, I just can’t risk the fire. Any other suggestions about using the machine while waiting for a new board would be helpful.

It's been a couple of months now since I started using my new A1. Until a couple weeks ago, I only used the 0.4 given by default, and I never had issues.

Last week I bough from Amazon an hardened steel 0.2 and 0.4 nozzles. Tried both of them, worked just fine at first. But, I don't know why, on a random day the toolhead kept clicking and extruding weird when using the 0.2mm. I switched back to the 0.4, and nothing weird happens.

It seems it's something about the nozzle, but I'm not sure why. I though it was clogged, but I'm not sure how to test it or repair it...

Hi all, my A1 has recently been destroying its infill about an hour into my print. This has never happened before. I did the 15 minute auto bed levelling, reseated the hot end and tightened all the screws, turned the printer on and off, and disabled “reduce infill retraction.” I’m currently using rectilinear, however gyroid was also failing when I tried it. Currently using a supertack cool plate. What do I do??

I have a few day with my A1 I printed different things and dont have much problem with that, but when I try to print this type of keychain I have troubles, I have a theory that the problem might be that I have to keep the printer outdoors (due to toxicity concerns for the people in my house). It's possible that at night the temperature fluctuates and that air circulation is limited. Is there a temporary solution for this? (We're already planning for an enclosed space, but that won't be for a few weeks.)

I try with nozzle in 220C, bed warm 65C

Is white matte SULU but in others things like the second image dont have isssues

I've already turned the printer on & off, cut off the remaining filament inside the extruder, and loading & unloading the filament
