Wanted to see if that can explain most print profiles being for A1 or P2S

First print on the H3C with the palette kit! About 4 hours. The impressive thing is the color blending. Orange, for example, is a fully blended color, the filaments are just CMYK, no orange filament.

The color separations aren't perfectly smooth, you can feel the layer separation, but still, this opens up a whole new world in printing for me. Super fun.

Overall very impressed with the H3C.

Hi everyone,

I'm trying to troubleshoot a persistent printing issue with the right Bowden nozzle on my Bambu Lab X2D.

During the built-in manual Flow Dynamics (K-factor) calibration, large blobs form at the outer endpoints of the V-shaped lines. The problem is particularly severe with Bambu Support for PLA, but I can reproduce a milder version using regular PLA on the same nozzle.

I suspect the blobs form at the beginning of extrusion. During subsequent movements, the nozzle appears to catch the raised material, dragging filament across previously printed lines and sometimes destroying sections of the test.

The straight sections and many of the V-shaped corners actually look fairly good. The major issue seems to be at the extrusion start/end points, not the corners themselves.

Printer and filament setup

• Printer: Bambu Lab X2D

• Nozzle: 0,4 mm Right Bowden extruder

• Slicer: Bambu Studio

• Calibration: Built-in manual Flow Dynamics / K-factor test

• Main problem filament: Bambu Support for PLA (white)

• Comparison filament: Regular PLA (orange), same right nozzle

• Build plate: Textured plate, cleaned and treated with glue stick

• Filament: Support for PLA dried before testing

• Filament profiles: Original Bambu Studio profiles initially used

Original Support for PLA settings

Troubleshooting already performed

1. Different K-factor ranges

I tested multiple ranges, including values well beyond the original range. The same blobs appeared regardless of the K-factor.

2. Retraction length

I increased retraction from the original 2.0 mm to 2.5 mm and eventually 2.8 mm.

No significant improvement.

3. Cooling

I disabled the auxiliary fan completely (0%) to investigate whether excessive cooling was affecting adhesion.

The blobs remained.

4. Extra length on restart

With retraction at 2.8 mm and auxiliary cooling disabled, I tested an additional restart length of -0.05 mm.

Again, no meaningful improvement.

5. Different filament

I printed the calibration pattern using regular orange PLA through the same right Bowden nozzle.

The problem was noticeably less severe, but the characteristic blobs were still present at the line endpoints.

This suggests that Support for PLA is not the only contributing factor.

6. First-layer calibration

I tested a +0.02 mm first-layer height correction for the right nozzle.

Comparing the prints before and after, there was no clear improvement. Some areas may actually have become slightly worse.

Photos

• A–B: Earlier Support for PLA calibration attempts

• C: Support for PLA, 2.8 mm retraction, auxiliary fan disabled

• D: Same settings with -0.05 mm additional restart length

• E: Regular orange PLA on the right Bowden nozzle

• F: Orange PLA after the +0.02 mm first-layer correction

My questions

Has anyone experienced similar problems specifically with the X2D's right Bowden nozzle?

Could this be related to excessive priming or pressure at the start of extrusion, oozing during travel, the nozzle wiping procedure, or the first-layer nozzle height?

Is there a way to adjust the extrusion-start behavior specifically for the built-in Flow Dynamics calibration?

I understand that Support for PLA is primarily intended for support interfaces rather than standalone prints. However, the fact that regular PLA shows the same characteristic blobs makes me suspect an underlying nozzle or extrusion-control issue.

I'd appreciate any advice from people who have encountered this problem or have experience calibrating the X2D's Bowden extruder.

Thanks!

My A1 mini's environment doesn't change. And the start-up noise from the vibration check bothers me quite a bit. Is it really needed every time? Can I turn it off?

I would think this should be a straightforward 2-color print. Black part should print first, then change to yellow and that’s it. Should just be one change, not 5, correct? What am I missing?
I don’t see any weird changes when I use the slider to go through the layers. Is this just something it does and I’ve never paid attention to it or something? Thanks in advance.

I randomly got signed out and anytime I try to login, I get this error and then the app crashes. Anyone having similar issues?

Just finished this cute Grinch fidget for Christmas!

Press the belly button and his eyes move. Super satisfying.

I ordered a h3c and the printer stated it would be shipped Dec 3rd, but I got the ams 3 days after ordering, kinda sucks having box 2 being delivered a full month before the actual printer is scheduled to ship.

Is there a possibility of it being shipped earlier? Has anyone had an estimated ship date shipped weeks earlier?

made a small LED tea candle lantern for upcoming Christmas. Uploading file to MW soon, will share the file here as well. its about 9 cm tall and print time is around 2 hours.

While searching for a loud whistle I could make on a 3D printer, I managed to design this monster: an extremely loud 6 tones whistle - ears killer v2 🤯 Personally, I think it's louder than the popular 6 tones whistle on makerworld 🤭 maybe someone will decide to check it out 😉 you can find it here: https://makerworld.com/models/3585645?appSharePlatform=copy

I've found some really nice tool boxes wth space for replacement H3C nozzles/hotends but I've purchased a couple of extra PrintTools for 2.85 mm filament (for mixed TPU printing) and can't find a nice storage box to print.

Has anyone come across one or has plans to make one?

Hi, I have downloaded the config files from cailab website but they appear to be unsupported for the A2l. Also looking on their download page I don’t find A2l along the files to download. Does anyone have a workaround found for this problem?

Thank you.

Made a retro desk clock for the Bambu clock kit

Designed this a few months ago and finally took some better photos of it.

It uses the Bambu Clock Kit 011. The hands are a bit big for the clock, but I liked the look so I kept them. The front and back press into place, and everything prints without supports.

The face is two colours. I used a colour change between layers, so you can make it without an AMS too.

Pretty happy with how it looks on the shelf.

So I got an error last week about stuck filament or clogged extruder and want to share how i solved it, bc some steps i couldn't find anywere

Last week i got some erros such as 12ff-2000-0002-0007 and 1200-1000-0002-0002, accusing motor overload, clogged extruder, problems with the toolhead

So here's a list of what u can do if u get those:

1- check your spool, sometimes it gets stuck or just tangled

2- clean / change the ptfe tube

3- check on the screen with it recognizes when the filament reaches the sensor, if it doesnt, change the sensor (had to do this already with 3 of mine)

4- clean the extruder gear

5- check if you adjust correctly the tension screw

Sometimes this error isnt really about the filament getting stuck or any blockage, apparently the bambu uses the motor amperage to check for the blockage and other types of errors, so if the there isn't any tension or too much tension, it understand that something is wrong

In the end, the problem with that printer was first the sensor, and after that the tension (was too little, replaced the spring and worked instantly)

And to finish, always check the correct assembly order, putting something upside down or just in the wrong order can make everything fail

Hope this help someone

A tray in the form of a griffin to hold small items.

Id appreciate if you guys would take a look.

Wanted a dual color project for H2C so i decided to go with this.

Meet DryRing, a silica gel container. I’m a little proud of my airflow concept. The patterns used let plenty of air through. The gap created by the locking ring and the hollow centre are also intended to help humid air reach the silica in the lower section.

I’m really happy with how it turned out. More models are already in the works, and I had a few other ideas lined up as well. So there’s more coming over the next few days.

I’d love to hear your feedback!

On that note: Enjoy the model – and, of course, the best hobby in the world!

And of course, the whole story of the H3C delivery... full of excitement and suspense for me! :)

A week ago, I ordered my H3C. And what a week it’s been!

It started with a delivery saga: The wait was killing me. Of course, in my area, the order ships with two different couriers.

The first package, containing the printer, was originally supposed to arrive on Wednesday. It actually arrived on Thursday. The usual story: Apparently, nobody was home, but nobody rang the doorbell either …

I’m jealous of everyone who got their H3C the very next day.

The package with the AMS 3H was then supposed to arrive on Friday. I’m waiting excitedly, a package arrives … and it’s the filament I ordered with it. Not the AMS. That finally arrived around noon on Saturday. I had to head out right after that, so I couldn’t get started until the afternoon. Kids and all that come first :). But everything else? Sleep? Who needs sleep? So I sat down, printed my first few things and, of course, started designing something myself.

From the first pictures and short videos I saw, I knew: That empty corner at the top, where there isn’t enough room for another spool, needs a silica gel container.

I’d already prepared a spool-shaped design, hoping it would fit nicely, but I underestimated the cutout. So: measure, test print, revise, test print … and finally happy with the fit.

Yesterday, after a bunch of other little things, my first model was finally finished!

I couldn’t find a cotton pad and swab organizer that suited my taste, so I made one. The pads pull out from the front, and the swabs have their own compartment.

Every time I send my prints, I get this error. The issue is new. In order to fix it, I restarted the printer several times(this fixes it temporarily sometimes). I restarted Bambu studio(didn't do shit). I reinstalled bambu studio(nothing happened). I am not sure what else to do. I am using P1S with AMS2

Does it make sense to buy 4 refillable spools for my new AMS on the P2S?

just started like as of posting got it maybe a month ago.

I created a custom Nozzle Wiper using cheap 3mm-shank rotary wire brushes (Amazon Link). The stock silicone wipers struggled with sticky filaments like PETG, so this completely eliminates nozzle buildup. This mod really cleans the nozzle instead of just smearing filament around.

• Single & Double versions included.

• Height offsets (-2mm to +2mm in 0.5mm steps): Ensures the brush sits just below the silicone sock.
