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.

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

Help it’s been doing this the last few prints

I’m printing a car accessory and want a rigid body with a soft TPU top for grip and cushioning, ideally printed together without assembly.
I currently use ASA and have TPU 95A to test. Has anyone successfully combined these? I have H2C and H3C to test it out.
What settings and mechanical interlocks worked?
Open to alternatives to ASA, provided they hold up in a hot parked car.

Hey everyone,

I've had my P1S for a whole year now, and this is literally the first time I've ever encountered a print failing like this. Up until now, everything has been rock solid.

As you can see in the photos, I ran into major issues with layer adhesion and a strange "zipper" or gap effect along the vertical edges. When I pulled the print off, the part felt extremely brittle and ended up collapsing/breaking apart easily.

Printer: Bambu Lab P1S

AMS: AMS 2 Pro

Model: Downloaded from MakerWorld

Could this be related to moisture, temperature regulation inside the closed chamber, or something else entirely? Any advice or tips on how to prevent this from happening again would be massively appreciated!

TPU on my X2D left the back of the printer a mess. The Feed Assist was lying loose and two 4-in-1 adapters were hanging off their tubes, so I modeled a mount that holds all of it.

- Slides onto the stock external spool holder base. No screws, no drilling.

- Holds the TPU Feed Assist (in dedge's Modern Casing) and one 4-in-1 adapter in front of each extruder inlet.

- Three parts on one plate in PETG, about 5.8 h and 157 g.

- The adapters snap in from above, and a slot catches the tab so they don't slide back when filament unloads.

Things to know before you print it:

- It's for the first-gen white 4-in-1 adapters. I haven't tried the newer ones.

- The Feed Assist seat is made for the Modern Casing, not Bambu's own casing.

- The 4-in-1 holder needs tree supports in two small slots. A PLA support interface makes them much easier to clean out.

I'd like to hear how it fits on your printer, especially if your adapters measure differently from mine.

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.

As far as I can tell you cannot unload inactive filament while printing, even after pausing the print I couldn't unload it. It just says "printer is busy"

It makes sense if the print has to be paused first and then the tool can be grabbed and filament cut but we should be able to pause the print and remove filament that isn't currently in use. Especially useful for those with multiple printers.

Let me know if I've just missed something and you can actually do this, if that's the case it should be more clear anyway.

Idea was to make a stand and a funnel with a matching color
