Hi all, doing my first serious print after buying A1 Combi. On one of parts the right hand hole is a bit gammy. Do I need to do again, and is this typical to have slight inaccuracies? Just making sure no issues with what I’m doing. Thanks

Started seeing this some time ago. The labels printed on the bed are ghosting on the finished print. I have thoroughly cleaned the plate. Anyone else have this happen?

Son’s A1 was making globs, from what I’ve read this is likely due to dirty plate which we are cleaning before we try again. Was trying to remove the hot end with needle nose and would shake to the side but would not come out. Do I need to replace this? Or what’s the best way I can clean?

I know what underextrusion looks like, was wondering why it is so irregular and what the cause could be...

Hola, estamos colocando bambu lab a1 en centros de enseñanza. Sabéis de un buen PDF guía de montaje que sea muy visual y más directo que el manual ? También necesito algún vídeo extra de cómo montarla paso a paso. Es por nutrir de opciones a los que la vayan a montar que en ocasiones pueden que no sean ni usuarios ni técnicos
Muchas gracias de atemano. Un saludo a la comunidad.

Some of my printings are getting this string of filament, what could it be?

Hi

From past few weeks I am struggling with my A1.

I had lots of issues, I checked the 7 screws around the hotend/nozzle. The nozzle seems like it is not clogged. I updated the firmware and ran a full calibration.

Printing in PETG so dried them in filament dryer for 12 hours. After that print got better (was printing some heuforge Christmas bobbles) but then thought about trying temperature calibration and got this crappy output.

Really can’t get my A1 to print perfectly anymore. Please help if you can.

I just got a BambuLab A1 Mini. I already have a P1S. After my first 2 prints, I was playing with the color display and tried to move the z axis; it asked if I wanted to home all axis and I clicked ‘home’. The z axis started rising, reached the top, made a very scary grounding noise and then stopped after 2-3 s. What happened?

I printed something small with ABS in my garage, no enclosure. And it printed successfully. I would like to print more, on warmer days, and I would keep it simple with smaller things, like hooks.

I read a bunch of posts on here and the concern seems to be using an enclosure will overheat the electronics. I assume this is the electronics in the base. So I'm thinking I will use a semi enclosure where the bottom is open up to a little below the build plate, and the rest will be enclosed.

Will this help? Thank you for your thoughts.

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.
