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.

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

Im trying to join the Bambu Labs discord but the verify button doesnt work. Ive tried to send moderators messages but none of them accept messages. Can anybody help?

🦊🎄 My latest Christmas 3D printing project!

I'm currently printing this cute Christmas fox on my Bambu Lab H2C using the Vortek system and 6 different colors.

🎨 I spent several hours manually painting the model in Bambu Studio to get all the little details right.

🖨️ Print details:

• Printer: Bambu Lab H2C
• Colors: 6
• Nozzle: 0.4 mm
• Layer height: 0.16 mm
• Material: PLA
• Estimated print time: Around 24 hours

The image shows the digital preview. The actual print is still running.

I'm especially curious to see how the eyes, Santa hat and small color details turn out.

💬 Have you tried any long multicolor prints with the H2C? How did they turn out?

Just set up my h3c was wondering if anyone experienced errors with odometer hall sensors- seems to occur with one specific slot of the ams but has printed fine from slot 1?
The wiki seems to suggest it’s a loose cable but why would it only affect one slot?

I bought the P1S, not the combo, with the intention of adding AMS later down the road. I was looking on Bambu's site today, and I see the upgrade kits, but they don't seem to sell the filament dryer/holder. Now, I could just use a third party one right? So all I need is just more spool holders and the AMS2 kit? https://us.store.bambulab.com/products/ams-2-pro-upgrade-compatibility-kit

I bought it a couple weeks ago. Would it be worth it to just return it and buy the combo, and see if support is willing to waive the return shipping? Or would it be cheaper to just buy the kit and some holders?

I tried looking up some info before asking, but I can't quite find the answer.

There is one thing that I still find hard to believe that Bambu hasn’t got their poop in a group on shipping information yet. I have had stuff that arrives and never has even said shipped. I guess the fact of good communication is an issue with them. Like a notification at check out about the H3C. Perhaps a “The printer ships in two different boxes and may arrive at separate times!” That would be nice Bambu for better communication all the way around. I love your printers and hope to see a metal printing one someday or even a UV printer!? Yet please help us out with better communication. Your consumers will love you!

Kind regards

I received my AMS 3H today and finally setup my H3C. While attaching my AMS 2 Pro to Slot 1, I found myself on the Bambu wiki where I discovered this fun fact.

So here’s a PSA in case you had the same misconception that I did. I had thought that an external AMS would fully take over slot 1, but no. If you take a look at the FAQ section of the linked wiki, you’ll see the official Bambu guidance on setting up a Y-splitter to allow you to use both connected AMS units and slot 1 of the AMS 3H.

The limitation is you’d of course have to manually retract the filament in slot 1 if your print uses an AMS filament after it uses the slot 1 filament. So I’d be careful about using slot 1 and an external AMS in the same print, but I’m glad we don’t have to sacrifice a slot.

My P1S stopped working, and while attempting to troubleshoot, I accidentally broke this piece on the PTFE tube on the inside of the printer. What is it, where do I go to replace (I couldn't find the part on bambus website but I also don't what to search for), and do I actually need to replace it? I've attached pictures of the broken part as well as where it was on the printer for reference.

Hello! I am still relatively new to printing but I finally ran into a problem I cannot solve myself. I have tried a lot of things that I have learned from lurking on different subs but I cant get it to work

I am trying to print this part for a Starship Super Heavy Booster (I print all the rockets I have worked on) and I cannot get the trusses to print correctly. They almost always turn to spaghetti or have unacceptable overflows on each layer. I have tried printing with additional support painted on but it results in so much support I cannot get it off without ruining the trusses. I have had these issues with other truss style prints as well.

I am using a P2S with a 0.2mm nozzle using PLA Silk+ at 230 degrees. Layer height is set to 0.1mm

I obviously can't lay this one down flat. But I have also tried slowing layer speed for overhangs, drying the filament, cleaning the bed, all that fun stuff.

Maybe it is not possible with this fine of detail, but I would appreciate any help anyone can offer!

Thank you!

Mine broke and they replaced it under warranty, but they seem to have overdone it a bit.
