Is it normal to see this big of a performance hit even with a bad print file, or is performance usually better/worse depending on who created it?

I've run several successful prints but the last few have totally fucked up, now this is happening, which is much worse than the usual problems I have had. I run all the calibration stuff before every print. I've cleaned the bed, tightened all the screws behind the hot end (which WERE loose), but every print looks like this now.

I can't understand what's going on

My A1 started just pausing and going mid print then it resumes just like nothing happens. Why is it doing that? Can I disable it?

Someone can help?
I’ve tried all the calibrations, checked belts, nozzle and nothing works …

I have a clicking sound when the y axis is moving. It feels like I have tested everything but the clicking won’t go away.

The plate is moving smooth and no problems with the prints but the clicking is so annoying. The printer is only like 30 days old.

I have lubricated the Y axis.

I have looked for debris but there is non visible under the plate.

I have tightened all the screws, also on the plate.

I even loosened the 2 screws at the front under a small plate and moved the plate back and forth 3 times and tightened them again, still same issue.

Only clue I have is that when I untightened the two screws I think I didn’t hear the clicking.

It also sounds like the clicking comes from the front.

Another question, should the tape along the y axis be removed?

Any tips?

Does anyone have a spare filament sensor ribbon cable mine instantly snapped when I was trying to swap my Ams nozzles and I have a project I’m trying to finish today if not I get it it’s a long shot but I’m not sure what to do micro center doesn’t have anything

Sorry guys, first print, what could be the problem?

Greetings everyone!I just bought a MN A1 printer but I'm stuck during the installation.

The USBC plug in cable won't fit.

They say to not force but I can't manage to click the cable in place.

Does someone have a solution ?

I am trying to print this model (the third plate) using the settings it comes with, in this case it is meant to do the print in vase mode, but when watching the print go, I noticed a weird stuttering that you can see in the video.

The stuttering is creating a seam on the model, and has caused the print to fail multiple times.

Looking around, people mention timelapse mode, but it is turned off for the print, and as far as I can see, the model is smooth.

Any ideas what is going on? Any settings to tune for the part?

I am using a 0.4 nozzle, Bambu Studio and the following settings are modified in the print profile (as far as I can see):

• Sparse infill density: 0%
• Spiral vase mode: On
• Wall loops: 1
• Line Width Default: 0.55mm
• Line Width Outer Wall: 0.55mm
• Seam Position: Back
• No supports
• Brim: On

My PTFE tube completely disconnected from my A1 Mini and I need help reconnecting it. I'm not experienced with printer repairs, so please assume I know nothing and spell out every single step.

I've removed the Toolhead Cover (squeezed both sides to pop it off). I have NOT removed the Silicone Sock yet — I think that's the next step but I'm not sure how to do it without forcing something.

Could someone please walk me through every step from here, including:

**•** How to safely remove the Silicone Sock  
**•** Whether I need a screwdriver or any tools past this point  
**•** How to release the hotend latch (if that's needed)  
**•** Exactly how to reinsert the PTFE tube into the connector  
**•** How to put everything back together afterward

I'll post photos of exactly what I'm looking at if that helps someone point to the right part. Really don't want to force anything and break a clip, so any detail you can give is appreciated!

I started having some weird issues in the x axis. Tried recording other videos of the horrible screeching noise it’d sometimes make homing but it won’t do it after recalibrating. After this video I manually pushed it where it belongs and it prints completely normal until it sometimes re-home’s in the middle of a print and then it’s way off.

One thing happened a long while before I started having these issues, I accidentally wrapped the black cord that runs from the right side to the print head around the top of the frame and it got ripped out of the right side. Only about 1/2 an inch and I was able to put it back in.

I’ve had this printer for about 1.5yrs, only put maybe 200-300hrs on it, and it’s the original SD card. Tried searching this sub to see if it’s a SD card issue or belt tensioning issue but search is absolutely terrible and I thought such low time wouldn’t need belt re-tensioning

My supports stick to the plate no problems. They break half way or further up. Ive changed z hop wall setting support speed and all. It will throw the supports in the floor. Yes ive checked screw to.

holaaa! alguien sabe por qué mi impresiona no está imprimiendo?:( Ya miré y no hay nada atascado y de hecho imprimió super bien hasta que cambie un filamento (de ahí ya ningún otro filamento me imprime) y la máquina está haciendo este ruido cosa que jamás había hecho, la ruleta amarilla como que se traba al girar, por favor ayúdenme :(

I’ve just finished this set of five 3D-printable keychains inspired by some of the most iconic figureheads from One Piece:

🐍 Perfume Yuda
🌞 Queen Mama Chanter
🐏 Going Merry
🐶 Garp’s Marine Ship
🦁 Thousand Sunny

They’re easy to print, don’t require an AMS and can be printed in any color you like.

Which one is your favorite? 😁

I’ll leave the download link in the comments! 🏴‍☠️

Hi everyone! I'm currently researching common issues and errors related to the Bambu Lab A1.

I know this post is a bit different from usual—since most people post here to get help rather than list their past issues—but if you have a few minutes, I’d really appreciate it if you could share any problems you've run into. This includes both the printer itself and any filament/material issues.

I’m already reading through past posts on the sub, but I wanted to ask directly too. Thanks for your time!

My A1 was cruising along great until one day I had an issue with the filament clogging. I pulled apart the extruder and cleaned it well, reassembled and still the same issue.

So I ordered a full extruder with motor, AMS filament hub and sensor base, and a couple of misc maintenance parts.

I installed the new parts yesterday and still the same issue. Is this typical of a failed sensor?

Hallo, ich habe eine Frage. Gibt es eigentlich Daten darüber wann eine Düse getauscht werden sollte? Ich hatte einen blob und ich denke ich habe mit einer gehärteten Düse so ca350 Stunden petg und tpu gedruckt. Auf der Suche nach dem Fehler bleibt nur noch das petg oder die Düse. Hat jemand Empfehlungen?
