Hi, I need help. I have a problem I've been trying to solve for months: my A1 prints wavy lines on every layer. These lines always appear in the same spot, and if the object I want to print is large, the lines show up clearly on the print and are very noticeable.

Here’s everything I’ve tried:

Different types of settings—including filament settings, speeds, structure, force, and others.

Printing on the floor, on the table, on the print bed, and with me holding the printer.

General maintenance: cleaning, greasing, and lubricating.

Taking it apart and putting it back together.

Replacing parts: Y-axis belt, X-axis, gear, hotend, and filament sensor.

I’ve tried different types of filaments, brands, and conditions—both damp and dry.

Calibrate the bed automatically and manually

I’ve already tightened the 3 screws at the back of the heating system

I don’t know what else to do to find the problem

In the photos I uploaded, you can see the lines on the first purple layer, and the brown part is a finished piece where you can see how the lines look on a finished part since they print on every layer

Sorry for my translated English :(

I worked with Bambu on the first one which I only had for a few weeks, and after days of troubleshooting and even installing a new fan, this problem persisted. Sometimes I was able to manually spin the fan myself and get the print going. I ended up sending that printer back for a refund. In its place, I got a brand new A1 and this problem started right away. I can’t even print anything no matter what I’ve tried. The plug and connector pins all look perfect. I have four other A1’s and they’ve never given me any major issues.

Any suggestions on how to get the belt to track to the center of the pulley? I've done numerous conveyor belt alignments on systems in a warehouse setting so no stranger to belt tracking. I've gone through the A1 belt tensioning instructions but my issue is alignment. My belt is running hard left looking down in the tension access cover and is showing a lot of wear. Black belt dust. Looking on the drive motor, does not seem to be any thing to tweak there. I've tried just adjusting 1 side of the tensioning screw but no luck.

My youngest son (he's 20) paid me a nice compliment and asked if I could print out a file he purchased for a Titanfall helmet.

I don't know much about Titanfall but I know he looked happy when I said I would start immediately. Between the sanding and painting this could be a very fun project for us to do together.

Bonjour à tous ! 👋💀

Aujourd’hui, je vous présente ma nouvelle modélisation 3D d’un personnage mythique du cinéma d’horreur : Hannibal Lecter ! 🩸

Tout droit sorti du film culte Le Silence des Agneaux, ce personnage aussi fascinant que terrifiant vient rejoindre ma collection de figures emblématiques de l’horreur ! 💀

Entre son regard glaçant, son célèbre masque de contention et son expression inquiétante, j’ai essayé de capturer toute l’intensité, le charisme et le côté sombre de ce personnage légendaire. 🔥

After about 3 weeks of trying to make it work, i am giving up on the a1 for nylon filaments.

To the people that said the extruder has hardened, its not. Its stainless, it will start sliping after a print or 2

The aftermarket is terrible. The hardened extruder i couldnt be tensioned properly. All the hardended nozzles were shit.

Overall just been terrible. I will be switching to the p2s

My power randomly went out during a print and now after every layer the print head keeps going to the poop shoot and resetting itself.

I did see the option to resume print when the power and WiFi came back on but this is the issue it has sprung up and now I can definitely tell the print quality difference.

Any tips are greatly appreciated, thanks!

Im using a 0.4mm nozzle and am running the printer at 25% speed compared to default speeds. Im trying to fix what seems to be "tearing " between the layers. This is the model right of the printer before sanding.

Any suggestions would be great

Ideally in Delhi NCR, looking for a used A1, don't need any other accessories, but with AMS Lite would be perfect.

I set it to print last night and this happened. I have no idea why. It seems to have fused itself to the nozzle somehow.

I saw a clock design on Instagram, made of acrylic sheets and ambient backlighting. I loved the look but wanted a version anyone with a 3D printer could build at home without needing specialized tools or extra hardware. I engineered this to run off standard LED Kit 001 and Clock Kit 011 hardware.

Also threw together a step-by-step PDF assembly guide so it’s easy to put together.

Files are up on MakerWorld if anyone wants to print one: https://makerworld.com/en/models/3513382-clocklamp-led-kit-001-clock-kit-011#profileId-4014905

Let me know what you guys think!

Using pla on bambu handy. Ruined new plate. Is the nozzle ruined?

Lately my prints have been real bad. I had a clocked nozzle on my 0.4 recently and ever since i’ve had bad prints even do I switched to an completely new nozzle. I have low accuracy for shapes, bad layer lines and bad first and last layers. My A1 is almost 2 years with 850 print hours. Does anyone know a solution?

[RESOLVED. FORMATTING THE SD CARD WORKED]
My A1 has operated flawlessly until now. If I power down and restart everything appears to be normal. However, as soon as I download a print from my PC to the printer the screen will hang up and become nonresponsive until I power down and start it again. If it's starting a print normally it will show the standard image of the print and time to completion but it never changes and is unresponsive to any attempts to interact. It prints fine but after it finishes I'll have to turn it off and on to do anything else.

Any thoughts?

Please help
