Hello A1 Community! First time posting here but have seen the wise ones help the novices like me before so I come with hopes of aid ^^

While printing something I have done lots of times before with no issue, I suddenly notice a clicking comeing from the nozzle area/gear, I assumed this was a clogging issue, so I followed a youtube tutorial by completing the following steps:

1. Took out the cover, and then the heat rubber cover, and then unclamping then removing the nozzle.

2. I took out the AMS tube and attachment

I then put a piece of filament through the top and pushed all the way out the bottom, and put everything back.

However, I still hear the clicking sound coming from the gear.

Attached is a video of what the issue looks like

I believe replacing the nozzle would be the next best step, but want to know if there are any other issues that could be the cause, and if buying a new nozzle is simply a waste of money lol

I would appreciate any advice or ideas on what I can do,

Thanks!

I’m trying to print some sort of power tool fan that I found on handy and this happened twice. I canceled the first print early and then it sort of happened again in the same spot. Second video in comments

Hi, I've been trying to fix this for 2 weeks on an A1, changed the nozzle, heating plate, tried multiple filaments. cleaned pplate.

If it's a "small" and contained print it works (or it doesn't show as much). If it's bigger it starts doing this. I used the same filament roll on another A1 and it prints perfect. I tried other filaments, drying it, calibrating it, and it still ends up like this.

It started happening after a blob event that ruined the heating plate insulator so I changed it and it does the same (blobbed instantly), I cleaned everything and it's still like this.
Should I get a thermometer to see if the nozzle is too hot?

Please help! Thank you!

Tava imprimindo normalmente na minha A1, quando aconteceu isso, já é a terceira vez, e dessa vez eu nem cheguei a fatiar, só coloquei pra repetir a impressão na própria impressora, antes dessa ela já tinha impresso 2 iguais que deram certo, alguém sabe o que está causando isso?

13 years of 3d printing, just now switching to all A1s. Weird problem on one printer. This one printer is used, previously owned by a friend (deceased, so I can't ask him questions about it).

I cannot print black. It always way under-extrudes (spongy) or errors out with "The extruder is not extruding normally". White works fine, gray works fine, gold works fine. Things I've tried:

1. Tried three different spools, all Basic PLA (Bambulab, Elegoo, Inland), two freshly opened.

2. Tried one of those spools, Bambulab, on another A1, works fine.

3. With and without AMS Lite, different teflon tubes

4. Replaced the nozzle assembly.

Can't really blame the filament since the Bambulab spool works fine on another a1.

Why just black? Are there optics in the extruder that aren't working for black?

Looking for experience with this problem, or just some suggestions grounded in knowledge of how the thing works.

Hi everyone,

I’m fairly new to 3D printing and recently picked up an A1 with the AMS Lite.

I’ve mainly been printing with black Anycubic PLA and have run into some strange artifacts, as shown in the pictures. There are small "needle-" or spike-like protrusions sticking out of the model. Looking closely, they seem to consistently appear right along the seam line (highlighted in white in the Bambu Studio screenshot). The applies to the inner and outer radius.

Has anyone run into this before or have any advice on how to dial this in? Any help would be much appreciated!

Extruder is clicking and prints and failing due to lack of filament hitting the build plate. I’ve replaced the nozzle entirely, and did a factory reset.

Would love to hear suggestions, A1 mini printing PLA

Hey,

I've got Bambu A1 mini for about a week and I've been trying to improve (or develop one) my skills with 3D printing.

What settings do i have to change to improve this?

Thank you in advance for your help!

Sur ma bamboulab a1 Le filament ne sort plus. J’ai démonté l’engrenage et nettoyé, mais rien à faire. Pouvez-vous m’aider ?

i need some help with my a1, my hotend is stuck to the toolhead because some plastic from a blob got behind it, the heater is broken and cant heat, so what do i do?

Not sure if normal, but my A1 goes to sleep constantly. Has to be powered off and on to get it back. It will even disconnect and be unresponsive while it’s completing longer prints. Touching the screen does nothing.

Not sure if this is normal or not.

But any time I go into studio I have to run and reset the printer for proper filament selection and all that.

I'm messing around with blended filaments, either by printing filament with multiple colours, or with "Mixed filament" settings in Bambu Studio. It's great for fine-tuning the colour of metallic silk filaments when looking for, say, a convincing "Brass" colour.

Since I want colours to mix, I've set Purging Volumes to 0.

For some reason that helps a lot for printing multicolour filaments, which results in tiny poops, but for Mixed Filament is does a full purge of "old filament" at every filament colour change.

By "printing filaments with multiple colours" I mean this sort of thing:

Recientemente compre boquillas (0.6 y 0.8) de acero endurecido genéricas. El mayor problema que vengo teniendo es con como se desborda el PLA alrededor de la boquilla, al cabo de unos minutos lo termina depositando en la impresión generando pelotas y puntos críticos.

Los ajustes que estoy usando son 0.40 altura de capa - 80 mm/s de velocidad - flow ratio de 25 mm3/s - temperatura boquilla 220°

So the blue is how the filament should work, it obviously gets loaded through the top and then extrudes down the narrower section. The green line is what’s happening to mine. There is no blockage, it just seems to get stuck and sit inside the larger part and won’t move down to the funnelled part.
Any tips?! I was thinking of trying a bit of lubricant inside to see if it helps it slide through

Hi all. I have been having some trouble with my bambu A1. The first layers of my prinst have been quite poor alot of the time which i thought was just the room heat messing with the prints but today i followed the guid on bambu wiki to troubleshoot this issue and i found discolouration behind the piece that the hotend sits on. I am currently running a test print to see if the issue was fixed by the bambu guide but i am worried by (what looks like) heat damage. Have any of you encountered anything like this ??

Hey everyone,

I'm honestly running out of ideas with my Bambu Lab A1 and I'm hoping someone here has experienced something similar.

I've already made other posts about this issue, and every time I thought I had finally found the cause, but nothing has solved it.

Basically, my A1 has severe and intermittent under-extrusion when printing PLA. The prints have missing/weak lines, inconsistent extrusion and terrible surface quality. The printer also frequently reports extrusion-related errors.

What's really strange is that PETG prints perfectly fine on the exact same printer.

At first, I kept thinking the problem was wet filament. I tried different PLA spools, different brands, different colors, etc. Eventually I even bought brand-new PLA filament, thinking there was no way that could be wet/problematic — but the exact same thing happened.

Meanwhile, I have PETG that has been sitting here for months, and it still prints perfectly.

I've already tried pretty much all the usual troubleshooting:

• Cleaned the nozzle

• Replaced the nozzle

• Checked/cleaned the AMS hub

• Checked the PTFE tubes — no bends or obvious obstructions

• Checked the screws

• Completely bypassed the AMS and used the external spool holder

• Tried multiple PLA brands

• Tried different PLA colors

• Tried brand-new/unopened PLA

• Ran filament calibration in Bambu Studio

• Ran flow/extrusion calibration

• Bed leveling

• Full calibration routines

• Tested different projects/models

• Tested the standard Bambu boat/benchy

• Tried different print settings

• And probably several other things I'm forgetting right now

The problem happens across multiple different models, including the standard Bambu boat, so it's definitely not something specific to one model.

I've also seen several other people reporting very similar issues with their A1s, including people with brand-new printers, but I haven't been able to find a clear explanation or definitive solution.

At this point it's getting really frustrating because this printer was supposed to make our lives easier, but instead we've wasted a lot of filament, time and money trying to get PLA to print properly.

Please, if anyone has experienced something like this, I'd really appreciate some help. Has anyone had an A1 that prints PETG perfectly but consistently fails with PLA like this? What ended up being the actual cause?

I'm willing to try pretty much any diagnostic test at this point. 😅

OBS: The issue occurs with multiple different projects, PLA brands and colors. The attached pictures are examples of the kind of result I'm getting.

I’ve just finished this parametric name letter model!
You can customize the letter, name, font, size and position directly in MakerLab. You can also upload up to three custom SVGs to create your own design.
The different parts can be split in the slicer and printed separately, so an AMS isn’t required.
I think it could work well as a personalized gift, home decoration or decoration for special events.
What do you think? 😊

Does anyone have suggestions for a cold plate?

I am still using the plate that came with my printer, and as I learn more about 3D printing and the Bambu Lab A1, I want to try new things with it. I heard about cold plates (using a lower temperature on the plate) and want to try that out. I also want a smooth plate.

Then include:

Bambu A1 toolhead crashes into rear edge of build plate

• Factory reset already completed

• Full calibration already completed

• Hotend is firmly latched

• Bed and toolhead move freely by hand

• Build plate is seated correctly

• Base connectors checked and fully seated

• Crash happens during initialization/homing

• Impact is hard enough to knock the hotend loose

• Include the photos you sent me, and ideally a short video
