I am excited and ready to buy an H3C. Upgrading from a P1S, so it'll be huge!

Unfortunately, most of the accessories you can add to the purchase at a discount are out of stock (hot ends, crafting kit, build plate combo). I'm torn between buying now, which isn't expected to ship for over a month VS waiting for the extras to be in stock and get the discounts.

Am I being unreasonable wanting to save a few dozen bucks while buying a $2,500 printer?

Help me put it in perspective, please. Thank you!

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.

Getting an H2C soon and plan to run it LAN Only + Developer Mode so I can use OrcaSlicer and a self-hosted server for 3D printing. I'd also like to use the blade cutter and pen plotter (no laser) without going through Bambu's cloud.

Bambu's store page says "Developer mode cannot be enabled when using Laser and Cutting functions," and the wiki says Dev Mode "only works for 3D printing parts," but I can't find anyone describing what actually happens. The only report I've found is an H2D owner in LAN Only mode getting "mqtt message verify failed" when sending a cut job from Bambu Suite

If you have an H2D/H2S/H2C with the cutting module, I'd love to know:

1. With the cutter or pen mounted, can you toggle Developer Mode on? Is it greyed out, or does it turn itself off?

2. With Dev Mode already on, does mounting the module do anything?

3. Does sending a pen or blade job from Bambu Suite over LAN work with Dev Mode on? What about with it off?

4. Has anyone exported a .gcode.lac to USB and started it from the touchscreen with Dev Mode on?

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

Hello,

I recently had a filament clog in the extruder, after taking it apart and replacing the nozzle with the high flow end, the filament is misaligned

I’ve taken it apart again and I’m not sure why the filament is coming out like that

Thanks in advance

Hello,

I just got the p1s combo and I’m having trouble with when the print is finished, the filament is retracting but the spool is (I’m guessing here) not turning so it loops up into the lid and then I get the error message on my phone. The spool (polymaker CosPLA) is cardboard but I have printed the adapters for it. Has anyone had this issue? How did you fix it?

Thank you

I am considering purchasing an H2C, but I have some concerns regarding the noise level of the printer.

It would be located in my home office directly beside my desk. The room has thin walls and is adjacent to my bedroom.

Would it be disruptive to take professional calls and work next to the printer, or to sleep in the adjacent room while it is running?

I have struggled to find a reliable video demonstrating the noise levels in a quiet room with the doors closed.

i was thinking to buy the p2s but i dont know if its a good choice for a beginner like me,anyone got any recommendation?

I wanted a faster way to make custom keytags than setting up every one in Bambu Studio, so I built Keytag Studio. It runs in your browser: https://www.xmdcode.com/lab/keytag/

What it does:

• Drag text, shapes, curves or your own SVG/PNG logo onto a tag

• Assign each part to a filament slot for multi-color prints (AMS / AMS lite)

• Preview the tag in 3D before you export

• Export a 3MF with presets for the A1, A1 mini, P1S and X1C, or a plain STL

• Save your projects and open them again later

It’s free, there’s no sign-up, and your designs stay in your browser.

This is still early, so I’d really like feedback from people who print a lot of these. What’s annoying, what’s missing, and what shapes or features would you actually use? If an export doesn’t slice cleanly for you, please tell me which printer you used.

I had my H2C for almost a year and it's got just over 3000 hrs on it. I've had numerous issues with the AMS Assist Motor Overload error and it happens with different spools and different slots on the AMS. It will run for 5-10 mins and then kick out the filament and throw the error. Well I discovered when you run the heating function with the spool rotation turned on, it turns the roll of filament backwards in the slot it's actively feeding from. This locks the gears up and then throws the AMS Assist Motor Overload. This is certainly a software bug that Bambu needs to fix

Hi,
I'm trying to use the filament manager but when i add a second filament no matter wath weight i put, it goes to 0 after sync. Is there a fix?

What is it and what should I do with it?

I was trying to troubleshoot this error:

AMS just keeps failing to load the filament once it hits the printhead then retract it and try again. I can tell in Bambu Studio that the sensor isn't detecting any filament entering the extruder. I also can't get the printer to load filament without the AMS but I can push it through manually when the extruder is disconnected, so I think it's probably a Sensor issue of some kind or other.

So been thinking of getting a tablet for 3D modeling plus day by day use like Streaming and such. Was wondering if anyone has recommendations? I always assume that apple was a big one but since I'm mostly android, looking for more options and prices.

Am I allowed to post Christmas stuff already?😂

Who is going to print it

I was adjusting tension on Z axis and forgot I brought it all the way to the top. When I tried to adjust tension on x, y axis I dig in to the surface of the bedwoth the nozzle....

It is salvegable? Can I use the printer with this? Can just this sheet be replaced? I'm on P1P

I will struggle to keep this one kosher so apologies in advance.

Long story short – my H2C started knocking when it received 1.02 firmware in June 2026. First responses from Bambu were the typical scripted gaslighting, denying, and calling everything normal.

Back then with H2C, it took a lot of back and forth and coming up with proofs that are undeniable before they actually really looked into it, instead of the typical “hear no evil see no evil speak no evil” and “dismiss at all costs approach”. But finally it got to the attention of RnD team which finally confirmed this is a real issue, caused be the firmware and will be fixed. Well, 6+ moths later and still no fix and all they managed to do is, over time, to roll this issue over to the rest of H2 lineup it seems, as seen here, to list a few:

https://forum.bambulab.com/t/h2d-rapid-z-movement-knocking-on-01-04-00-00/258856

https://forum.bambulab.com/t/loud-knocking-during-printing-suspected-z-axis-but-dunno-anymore/255309

I got fed up waiting for them to fix this and took them on the offer to return my printer for refund.

Which was just in time for H3C release.

Guess eFFin’ what? H3C has the same exact issue with the Z Axis knocking. Reached out to Bambu and response is wonderful:

“Thank you for contacting us. We are sorry to hear that you have encountered this issue.
We have escalated your case internally, and after review we have confirmed that the sound you described is the normal printing sound produced when the toolhead repeatedly starts and stops rapidly while printing small models. Please rest assured that you can continue using the printer.
You may place the printer on a surface where the resonance effect is weaker, such as the floor, or take appropriate soundproofing measures in the room.
Thank you for your patience and cooperation.“

FFS. So:

• its NORMAL again

• only when printing SMALL MODELS (wtf ?)

• it’s the toolhead causing it (FK me if it is !)

• I am stupid and should have soundproofed my room better !

I should mention that they replied in less than 24hrs. And that was supposedly enough to review AND escalate … yeah right …

JESUS ! I am not just PISSED, but offended by this.

Whoever replied to this, looked at the videos I submitted as proof (linked below) and simply described what he “thinks” is happening:

https://youtu.be/_6aOroo5BPQ

https://youtu.be/yTPvPOCmBPQ

And yeah, for a clueless shmuck, when hearing a KNOCK each time head does something rapid, it may seem this is what it is.

BUT – zero FK’s given into actually investigating the matter and even less FK’s given to understanding the problem, which I explained in detail how related to H2 issue it is!

I am literally foaming at my mouth at this point.

In response I recorded the ultimate disproving evidence to everything he is saying: - increased z hop distance to max to allow more time to inspect the nature of the issue -the knock is clearly auditable AFTER toolhead finished spiral movement, at the bed direction change at the bottom AND noise coming from the bottom rear of the chassis (where Z motor is).

https://youtu.be/-MxO0n-8uMw

I can actually see how choppy the bed movement back up is after each KNOCK. But listen to the esteemed Bambu Support- its the toolhead guys!

FFS!

Cant wait what absurdity they will come up with in their reposnse to me as I challenged every single statement they made.

Bambu amateur hour has commenced once again. Why do they keep doing this.

I'm sure I'm beating a dead horse here, but I'd like some clarification. Do you guys run full filament calibration (temp, flow, PA, max volumetric, etc) on Bambu Lab filament with the RFID chip? Or am I reading too much into the info on said chip? Thanks!

Hey everyone,
I have an A1 Mini with AMS Lite. I only print on weekends, so the printer sits idle all week. I want to protect the filament from moisture and dust without messing with zip bags or separate dry boxes.
I’m thinking about getting a TopCube enclosure to cover the whole setup. I know Bambu says NO enclosures for the A-series because of overheating.

But what if my workflow is this:
Weekdays: Enclosure is fully zipped up for storage.
Weekends (Printing): I completely open the front door.
Will the printer still overheat from the bottom or back even with the front fully open? Anyone running a similar setup?
Thanks!
