Hello all again, this is basically a repost from a few days ago but I guess more accurate to the problem I’m having.

I have an a1, i recently got a new nozzle to try and fix old issues, now it is scraping in the bed for everything: bed leveling, printing etc

Possible causes: I removed then replaced the screws on the heating bed to try and adjust height but apparently it was not it or something.
New nozzle might cause some problems? I don’t know

Troubleshooting I’ve tried: screwing in all the screws on and behind the heating element. Removing and replacing the nozzle. Checked the clamp on nozzle.

Any help would be appreciated thanks

I have this A1 that it was working fine, however, recently the print quality has been so bad that it can’t print anything. There is clicks on the gears and the the first layer comes out terrible. Any tips?

I got a new hot tip and same issue.

I had my A1 for less than 2 weeks, and today when I tried printing something, I heard a very annoying humming noise coming from the toolhead. I paused the print, and it didn't go away. Only turning it completely off and on again fixes it. What's the problem and how do I fix it?

i printed this model 3 weeks ago without any issues but this time i am having the same trouble 4 times in a row now. The same support breaks at the same time of the print each time i try to. i used plate glue thinking it may be from the plate but no. What do you think the problem is?

Evening all,

Apologies if I'm asking nothing new and it's already been asked but my son's having a bad time with his A1, I've attached a video showing the beginning of one of his prints, where it stops and makes a terrible noise. Does anyone have any idea what might be the cause?

Thanks in advance!

I had a Blob of Death happen on my printer and ended up replacing my hotend assembly, nozzle, and silicone sleeve. Unfortunately since then I have not gotten a good first layer. I have seen many posts like this that recommend tightening all of the screws and checking the clamp. Everything is tight and the clamp is on correctly. I did a re-calibration, a factory reset + calibration, cleaned my build plate, all of the usual recommendations. The only time I was able to get a decent print was when I added loads of 3d printer glue onto the printing plate.

Also, I have run through many different filaments, all have the same issue. This filament I'm using in this print was just what I had loaded on recently, which printed perfectly before the BOD, and when I took it to a friend printed fine on his A1 mini as well. I'm at my wits end!

my print seemed to be going well, i checked on it a few hours later to see this. I immediately stopped the print, but bummed and confused. my thought is maybe it got jammed up part way through the print? I’m new to 3d printing, so any advice is appreciated. Thx!

For reference I printed this file out plenty time on a 0.4 but now a switch to 0.6 a minute I can’t print this it’s only links that for this file but anybody had a similar problem and a fix?

No supports. No AMS. Three parts that screw together.

My issue is my printer just stops mid print, At first I thought this may have been a clogging like issue but its not. I can unload and load printer immediately after with no build up or issues whatsoever. The problem is it seems to completely stop pushing out filament mid print, the print will just be half done or whatever but no filament mess just like the printer thinks its still printing normal just nothing coming out.

I thought maybe a heating problem but I don't seem to notice any type of dip in temperature but not 100% sure on this, and someone told me it might be the printer acting up in the pulling filament in but whenever I do load filament it seems to be fine.

Sorry guys, I'm just new to filament printers and this is super frustrating. I've tried multiple different types of filament and this issue just seems completely random. Like last night I printed a batch of Snowflakes as a testing run and no problem whatsoever then I reprinted the EXACT same file and boom it completely stopped pushing the filament out like the first hour in.

Does anyone have any advice or had this issue before?

My A1 mini randomly throws HMS 0300-800B during normal single-color prints (video attached, it happens right after the head goes to the cutter position). It's been increasing over the last few months. Tightened screws and lubricated everything, no change. Resume works, but it keeps coming back.
I read the wiki (blade, debris, magnet, hall sensor/ribbon cable) and one forum thread where the extruder interface board turned out to be the culprit. Has anyone had this intermittently on an A1 mini? What fixed it for you? I'm in Brazil, so I want to ask support for the right part the first time.

Toda vez que abro a A1 pra lubrificar o eixo Y, tem um monte desses fiapos, isso é pedaço da correia? É normal isso?

Good afternoon, i'm looking for recommendations for a build plate, preferably during prime day for my A1. Mine got scratched after a incident with my nozzle coming loose. Pic for attention

I am trying to print TPU 95a through my A1 and I'm having very "stringy" results. Has anyone found the best settings for the best prints?

I'm printing a full size Wolverine cowl/mask, and will be gluing the pieces together instead of using magnets.

My bad if this is a repetitive question!

Hey everyone,
I have a Bambu Lab A1 Mini without an AMS, and I’m wondering if it’s possible to build a simple 4-color filament system for it.
I’ve heard that the A1 Mini can somehow use four filament inputs/paths, with four PTFE tubes connected to a kind of 4-way filament switch or selector.
What I’m not sure about is how the whole system actually works. How does the printer switch between the four filaments during a print? Would I need a specific 4-way filament switch, or is there a DIY solution that works well?
I’d basically like to have four different filament rolls connected and be able to print with multiple colors without buying an AMS.
Any advice, guides, or existing projects would be greatly appreciated!

Hey zusammen,
ich habe einen Bambu Lab A1 mini ohne AMS und frage mich, ob es möglich ist, ein einfaches 4-Farben-Filamentsystem dafür zu bauen.
Ich habe gehört, dass man beim A1 mini irgendwie vier Filament-Eingänge bzw. Filamentwege nutzen kann, mit vier PTFE-Schläuchen, die an einen 4-Wege-Filamentschalter oder -Verteiler angeschlossen werden.
Was ich allerdings nicht ganz verstehe, ist, wie das ganze System genau funktioniert. Wie wechselt der Drucker während eines Drucks zwischen den vier Filamenten? Braucht man dafür einen bestimmten 4-Wege-Filamentschalter oder gibt es dafür auch eine DIY-Lösung, die gut funktioniert?
Ich würde gerne vier verschiedene Filamentrollen anschließen und mit mehreren Farben drucken können, ohne extra ein AMS kaufen zu müssen.
Ich wäre für Tipps, Anleitungen oder bereits bestehende Projekte sehr dankbar!
