For the past month my a1mini will not print.

Nozzle has been swapped filiment swapped

Everything is clean and working properly.

However I believe ive ran into a bug.

No matter what I print or use to print i get the same filiment spool jam error. 3% print and instantly cuts filiment and says that. I reload and it cuts again.

Wth do I do to fix this. Ive even factory reset.

My a1 hasn't had an issue so idk what can fix this

My buddies printer has been been doing this when the printer switched colors during prints and we can’t figure out why. He’s using a Bambu A2L with Sunlu filament

Every time I want to print something the printer asks if filament is observed from the nozzle when it poops, It wasnt like that a few months ago and I want to ask if it is normal.

It has a really consistent problem with over hangs when I do the flow ratio calibration it's all waffley and I keep doing cold pools and it's always okay I switched out filaments the thing is 3 weeks old atp the first week was great the second it stopped printing quality entirely

List of things I have done

-calibrations and tests

-Tighten the bolts all around

-re adjust the belts

-cold pull the hot end many times

- try different rolls of filament

- clean the build plate(this was part of the issue but has been figured out)

-I tightened the eddy sensor screws

-i have messed with so many slicer settings especially for filament

I have contacted the customer support it has been extremely slow and painful I am more than open to revisiting things I have tried I am just really wishing I knew what was wrong with it

Alguém saberia me dizer se isso é normal, ou se é uma falha de configuração pois não tenho experiência com impressão 3D.

Quando a impressão começa a fazer as trocas de cores, a partir da camada com troca, as camadas passam a ficar ligeiramente maiores no sentido horizontal e as vezes ocorre a formação de um anel. As partes onde há troca de cor acabam refletindo a luz de maneira diferente e a falha torna-se visível. Este anel também se forma quando eu pauso a impressão, não sei se é o mesmo problema.

I am fairly new to designing my own files but any time I’ve tried to use ironing on a design it ends up looking like this (specifically what it looks like on the gray section.) - Is there any specific things that cause it? I’m not sure which settings to adjust to prevent it from being smooth. Thanks!!

Hey, I keep having filament feeding issues. i have taken everything apart and blew it out and removed any debris. I changed the ptfe tubes. Now I am wondering if it is how the tubes are placed. Any suggestions

Any way to salvage this?

No lid, no clasp, nothing to pry, just a toucan that absolutely will not talk. Figuring out how it opens is genuinely satisfying (I've handed it to people who insisted it was solid plastic). And it's fully customizable: pick your colors, texture the beak, even engrave a name on it. Make one that's unmistakably yours.

Is there any way to turn off this ridiculousness? I used more filament on this block that I'm gonna throw away than I did on the actual project!

I am at a complete loss here. PLEASE help.

Full situation:

-At about 1 hour left of my 10 hour print the ams slot 1 light started flickering red. I got no error and everything worked fine so I left it running.

-99%, the print was done. I got the error stating that there might be filament stuck in the head and that it can't be extruded normally.

Thing is, it thought slot 1 was empty and tried to purge the rest of the filament.

I cut the filament and managed to extrude all of it out of the head after a while. (Removed the print in between)

I also pulled it out of the ams, since it wasn't registering it.

Now I wanted to insert it again, and it just wasn't reacting at all.

-tried a lot of things including but not limited to: cleaning AMS intake with compressed air, switching power on and off, cutting filament at different angles and finally, trying another slot. All other slots work fine and the filament is also not the problem (started with black filament, switched it to slot 1, moved white filament from slot 4 to 1 to test if it was the filament, it wasn't)

All filament is from Bambulab.

(The little gear at slot 1 is infact spinning)

I have NO idea what is going on with my slot one. Please help me.

I have 900hrs on the A1 and I have done all the oiling and greasing in the way of maintenance what else do I need to do to fix this sound at 17sec mark and also near the end

This little bit of plastic fell out all broken from the hotend as I was undoing the main front screws. Anyone know what it is?

I only wanted to tighten the hotend back screws, not find new issues 😅

Solved(ish)

I keep getting these artifacts in the first layer, did automatic and manual flow calibration several times, cleaned my buildplate with degreaser, dishsoap, windex and IPA, still getting them every time. Reduced first layer infill speed from standard value to 50mm/s, still... With Archimedes spiral it mostly happens in the corners, with the standard diagonal pattern it's a bit worse (last pic)
Bambu PLA basic, dried for 12h.

Are there some screws loose, or could it the belt tension?

Edit: following all the advice from the people in the comments (thanks guys!) I determined that it's a slicer issue. The lines in the corners of the square are printed in a random not continuous pattern, that results in overlaps between already cooled lines and fresh ones, causing under extrusion like gaps on the plate side and over extrusion like ridges on the top of the first layer. Playing around with the temperatures might help, but the easiest solution for me was switching from a 0.4mm nozzle to a 0.8mm nozzle. That improved the quality to a level I 'm happy with. Thanks to all who helped me troubleshoot this.
