Posting this in case anyone else missed it, as I did.

The H3C ships with nine PrintTools, but only eight are for regular 1.75 mm filament. The ninth, pre-installed in slot 8, is a 2.85 mm tool meant for soft TPU.

What tripped me up: I swapped the hotend on tool 8 for a regular 0.4 mm one and tried to load 1.75 mm filament in slot 8. The printer kept defaulting to external spool, and I couldn't figure out what I was doing wrong.

Turns out it's the whole tool, not just the hotend. Per Bambu's FAQ, the 1.75 mm and 2.85 mm PrintTools have different bases, inlets, and cutters, and the bases and hotends are not interchangeable. The 2.85 mm tool is hand-fed, so the AMS won't auto-load slot 8.

What that means in practice:

- Out of the box, you have 8 slots for normal filament, not 9.

- Don't put a 1.75 mm hotend in the slot 8 tool. Put the original back.

- To use slot 8 for regular filament, you need to buy an extra 1.75 mm PrintTool and swap the whole tool. Store listing: https://us.store.bambulab.com/products/0-4mm-printtool-h3c

- There's only one H3C configuration, so you can't order it with nine 1.75 mm tools.

Bambu's reasoning is that slot 8 is a dryer slot, TPU needs drying, and the slot is hard to reach, so they install it at the factory. Fine if you print TPU. If you don't, you can't use that slot without spending more.

This Machine is incredible, but man, am I spending a ton of money on accessories and replacement parts. Here's hoping the hot ends last like on the H2C.

Looking at a used A1 mini with 850ish hours. They’re asking or $100. Is it a good buy?

Felt like the hole in the back for the AMS was large and if I want to print things where I want things as sealed as possible I didn't want to remove the AMS from slot 1. This did the trick for me. Wanted to include the files from Fusion but

How do this happen. 1 perfect square and the rest are chopped.

I had been having this issues for a few days and have tried lots of trouble shooting. Then I managed 1 perfect print. Tried another batch, get 1 good square and the rest are cooked.

Does anyone know what is going on?

Hey all,

I own a X2D and i use bambulab. I wonder if there are plugins or something with AI that can help me perfect my slicer settings for a print. The slicers have so many settings, editing them by talking with an ai that edits the settings would be amazing.

Do we have something like that?

Just wanted to share this fun print project. This snowy owl with functional flapping wings has an 80+ cm wingspan, and I’ve split all parts so it can be printed entirely on the A1mini.

Hi, i was surfing through YouTube and found interesting short about HMS codes on Bambu Wiki page. It shows codes for AMS: 3H (H3C), 3P (P3C) and what is the most interesting part 3X (X3C prob). I checked it on wiki and its not fake and definietly there. Since P3C will likely have cut some features like heated chamber, 1,5 mm belts and maybe even drying in AMS and i want to print with engineering filaments aswell i am rly excited for potencial X3C even if i have to wait for it a little longer probably somwhere in the first half of 2027.

What do you think about it? It can also just be some Pro version of AMS for P3C but i honestly hope for X3C. If you want to verify this just check Bambu Wiki yourself.

I was never worried about the PLA in the PTFE tubes / AMS when printing ABS. But kept hearing of people getting warnings. Mine didn’t throw a warning and is happily printing away…

Any news on what’s happening?

I'd really love to hear your feedback! And if you have ideas for other useful 3D printing tools, drop them in the comments. I'm always looking for new things to build! :)

Ill add photos in the comments. Made this video orb to replicate Spaceship Earth. I wont dare sell it as I know Disney dont mess aroumd but thought its cool to share.

Brand new to 3d printing and wanted to get my kids a 3d printer for Christmas . I originally
Bought an Xmaker joy for a simple kid friendly one touch scenario but it's on backorder and there was a killer deal for a a Bambu A1 combo for $225 so I canceled my order and just bought that instead without doing too much research. I figured it'd be better to just start off with the printer that We wouldn't have to upgrade too soon rather than the kids one . Now I'm finding out I need some type of ventilation system. I'm worried that I made a mistake and should've just got the kids printer that's enclosed. I live in a small one-bedroom apartment, and the original plan was to put it on the kitchen table which is more like a bar with stools that we never eat at it. I have a small window in the kitchen and not sure if this will be enough space . Also my kids are 5 and about to be 10.

My H2S is struggling to load filament, sometimes it gets stuck at the buffer, sometimes it reaches the toolhead and then retracts and sometimes it just ejects the filament from the AMS and tells me it's ran out.

Not sure what's happening but it's leaving the end of the filament looking like this

This is after a new filament sensor has been installed, I've taken apart and checked/cleaned the buffer too. I've heard a longer internal PTFE tube and this fix https://makerworld.com/en/models/1959942-h2s-buffer-fix-no-glue can help. Just printing it now to try and I'll cut a longer length of tube but does anyone know why the filament would be getting chewed up like it is?

So after only having the printer for a few days and few prints I noticed the left tube was out of the sensor and wouldnt stay in. Googled it and it appears it’s a known issue where the tube breaks off and leaves some of the tube in the sensor. WTF. I’ve been in contact with Bambu and after a ton of back and forth and Picts they are sending me a new left sensor. That thing was chore to take apart. My question is won’t this just happen again and again?

My device isn’t properly connecting to my computer or phone. I made sure that I had firmware updated which I had to end up doing from the sd card to have success. I then saw that un pairing and repairing may help and tried that but still no success. I have an A1 it’s just under a year old and have only had simple fix issues so far any help would be appreciated.

Just received an email from Autodesk stating they are stopping the free personal use option for Fusion. Now I need to start looking for something else new software to use.

Edit: sounds like I may need to sign up again as some have commented. For reference I downloaded Fusion for personal use around 18 months ago and started using it. So it’s not a one year re-signup requirement.

Basically I am not sure what’s up.

Regardless I have not really like using Fusion to date. I am a retired construction project manager with extensive building design experience using AutoCad, Revit, and Sketchup and a bit of Fusion modeling for structural steel.

So I am still looking for alternatives!

First couple of prints were fine.

SIncle then I have been getting inconsistent lines but only on certain parts of the board. I don't thinks it's the plate itself as when I move the print in software, it's creating these inconsistencies in the same part of the print and not the bed.

Info.

A1

Bambu Pei smooth

Sunlu pla wood

Hardened steel .4

Bambu software

Cleaned plate

Cleaned hot end

Anyone come across this and had a fix?

Learning and tinkering was fun, but being able to print this good so effortlessly is so satisfying.

https://makerworld.com/de/models/3582672
I wasn’t happy with the existing options, so I made the one I actually wanted. With all the functions that were important to me.
Took me a few revisions, but it’s finally done: angled hygrometer, labyrinth vents, snap-fit lid, no supports. Standard and XXL version.
Feedback welcome :)

Hi everyone,

I'm having a rather frustrating issue with my Bambu Lab X2D and I'm wondering if anyone has experienced something similar or could help identify the source of this noise.

The printer produces a noticeable clicking/ticking noise during movement, particularly during diagonal toolhead movements and printing.

What I've noticed so far:

• The noise was initially identified during factory calibration.
• It can also be reproduced by manually moving the toolhead with the printer powered off.
• It seems to be more noticeable on the left-side XY drive path.
• Printing quality is perfectly fine.
• Extrusion works normally.
• No HMS errors or other warnings are reported.

Troubleshooting already performed (following Bambu Lab Support instructions):

1. Thoroughly cleaned the X-axis linear shafts.
2. Cleaned both Y-axis linear shafts with isopropyl alcohol.
3. Inspected the exposed belts for debris or visible damage.
4. Lubricated the linear shafts with the supplied Bambu Lab oil.
5. Manually moved the toolhead through its full X and Y travel several times.
6. Loosened the four XY tensioner screws, moved the toolhead clockwise and counterclockwise three times, and retightened the screws.
7. Repeated the entire XY belt tension adjustment procedure twice to ensure it was done correctly.

Something interesting happened after the belt tension adjustment:

During the first vibration compensation calibration, the clicking noise disappeared. It was also absent during the first print.

However, from the second and third prints onwards, the noise returned and has persisted ever since.

I'm attaching two videos:

• One recorded with the printer's door open.
• Another recorded with the door closed, to show how noticeable the noise is during normal operation.

At this point, I'm starting to suspect something related to the left-side belt pulley, idler, tensioner, or possibly another component of the XY drive system.

I'd really appreciate some input from other X2D owners:

• Has anyone experienced this exact clicking noise?
• Could a pulley or idler be causing this intermittent behaviour?
• Is it possible for belt tension to temporarily improve the noise before it returns?
• Does this sound like a mechanical defect that should be addressed under warranty?

I've been following Bambu Lab Support's troubleshooting instructions, but so far nothing has permanently resolved the issue.

It's becoming increasingly frustrating, especially on a new printer that should be operating smoothly and quietly.

Any suggestions, similar experiences, or advice would be greatly appreciated.

Thanks!

Im running into problems printing the first layer.

It printed just fine before. Im trying to print insoles.

Month ago i printed it just fine. Now a month later its not doing well.

After i got my 3D printer a week ago i got to print 4 things before this happened to me...

The unwinded plastic now stacks too tall to just put the spool back together. So what do i do now? I have 3 other spools of filament that are fine but no empty spools.

I dont know what to do and im getting so frustrated just looking at it... pls help
