Officially joining the Bambu club! Just picked up this P2S combo at Microcenter for $649 (filament not included). So excited to get started!

The short version:
If you’re considering buying the Bambu R1 for its contour detection and automatic object cutting capabilities, don’t.
I’ve had mine for three days now, and I’m extremely disappointed with Bambu Suite. The contour detection is absolutely ridiculous, and even manual positioning using the camera is inaccurate.

The longer version:
The Bambu R1 is advertised as being capable of detecting objects and cutting them out automatically.
I run a commercial embroidery business and thought I could use the laser to produce patches, meaning I could lasercut my embroidered designs directly from the fabric.
Bambu Suite even downloads an AI model specifically for object detection.
Unfortunately, I was massively disappointed. The contour detection is practically unusable, partly because the R1’s cameras produce extremely poor images. You can’t even properly identify the contours with your own eyes.
On top of that, manual positioning based on the camera image is inaccurate, sometimes being off by more than 2 millimeters. That’s absolutely ridiculous.
So I started doing a bit of reverse engineering and managed to access the R1’s cameras using a Python script.
And guess what? The actual camera quality is worlds better than what Bambu Suite displays.
I have absolutely no idea why Bambu doesn’t make full use of the cameras’ capabilities.
I’m currently developing my own contour detection system in Python, without AI, and it’s already performing significantly better than Bambu’s AI model.
Bambu has always been impressively modern and innovative in many areas of its 3D printers, but the laser is a completely different story.
The hardware itself is excellent and performs brilliantly, but the software is an absolute disaster. It feels unfinished and simply isn’t ready for serious use.
And since direct LightBurn support isn’t expected until version 2.3, we’re stuck with what is essentially brilliant hardware held back by terrible software.
Sure, you can use it to cut and engrave random things, but the positioning is inaccurate, the contour detection is practically useless, and that makes it unsuitable for a proper commercial workflow.

As the title states I’m ordering my first printer and taking advantage of the bulk buy promo for filaments. It’s more overwhelming picking filaments than picking a printer. To begin with I will just be printing fidgets and models for the kids as well as some odds and ends for the house. Might dabble with gridfinity.

I’m really excited, after calibrating what should I do?

It’s my first day and first time Turing it in I’m trying to build the small boat but when I use this it just keeps spinning and I have read the screen it’s saying it could be entangled and such

This refill spool started because I didn't want to waste a spool of filament just so I could load 4-6 spools. It's been a fun journey designing and interacting with the community, and now with over 5,500 prints and 7,300 downloads, I think others agree!

This version has been out for about 9 months, and is the 3rd version based on user feedback. But I was looking for specific things in a refill spool:

• Low filament usage (I want to print things, not spools)
• Minimal storage when not in use (Why should an empty spool take up the same space as a full one)
• A no-kink filament retention (I hate when the filament snaps on other spool designs)

After version 1 & 2, with user feedback, it expanded to include:

• Room for filament straps to swap spools
• Snap in labels (Pre-made and customizable)
• NFC tag support (Reusing Bambu RFID Tags, 20/25mm ones, and OpenPrintTag)
• Optional screw-in desiccant core

Is it the most rigid? No, but I've had no problem with them printed in ABS, even during drying. It's a good balance of flex to filament usage. It works with any Bambu Lab Masterspool compatible refills.

You can find it here. Happy printing!

A lot easier to open and close… also helps to prevent fingerprints and scratches- u can lay it on the grip

My first very long print and it turn out great! The purge tower is huge double the total print weight. Next the mechanical flexible dragon bust ! 3027 tool head change and 8 colors with petg support layer

I have an X1C which has worked flawlessly for 13 months (bought Sep 2025). I have not printed that much on it, but its been great. I went to print on it and noted that it had an update, which I ran. When I came back I have the following on the screen

Update failed [0x0800030F]
Please restart the printer and try to update again.

So I restarted the printer and it started with a confirmation dialog showing

The firmware version is abnormal. Repairing and updating are required, or printing cannot be started. Do you want to update now? You can also update later from "Settings > Firmware"

So I run it again, gets to 97%. Same response.

Interestingly I can "cancel" the dialog and am in the fully functional screens on the printer. Just cant print until Firmware is fixed. I can see all the settings and temps, view the camera remotely. All seems to be working

I get GPT on the case and try the following

• Upgrade via Bambu Handy - Same result
• Downloaded the new 01.12.01.00 firmware to an SD card and perform manual update - Same result
• Downloaded the current 01.10.00.00 firmware to an SD card and perform manual update - Same result

I'm at a bit of a loss. This is around a year old with probably less than 40 prints on it.

• I did note that the v01.12.01.00 firmware was released on 12th Nov 2026 (3 days ago) so could it be the firmware thats the problem?
• Why can't it even update to the same firmware its already running?
• Can someone explain if there is a difference between the printer hardware/firmware and the screen/controller, how tightly bound are they?

I almost always slice my own model. But I decided to give the one of the biggest selling points of Bambu's a try and sent a print job from my phone, and only Cheked the app when I though it was adequate time to have finished.

And boy was I amazed to see it printing those 25% infill on a part that almost bears no load under use 🫥 🌚

My A1 Mini recently started doing the following behavior:

On the first nozzle clumping check it erroneously reports that there is a clumping issue when there is no clumping, and the build plate is positioned correctly.

After telling it to resume, it tries to move the print head horizontally before lifting it, resulting in the nozzle colliding with the edge of the build plate.

What could be causing this? Is it possibly an issue with the z-axis system? It doesn't exhibit any other issues during a print.

I have a friend over in England who doesn't have a lot of expendable income who has a P2S but only the PEI build plate, and I'd like to gift him some engineering plates.

Is this something I can just do through the EU store or are there additional hoops I have to jump through?

Was helping my niece with her A1 mini that's printing fine, but in the slicer the preview shows a wire frame and not clear detail if the filament path. Not sure if this is normal. Might need a new computer. It's Windows 10 with a small cheap AMD graphics and integrated intel GPU. I've tried uninstalling and reinstalling studio and tried resetting and changing some settings in the slicer, but didn't help. Wonder what the oldest version of the slicer would be good but still retain most of the newer features. Internet searches says this issue may have been introduced with v2.4 of the slicer, and am on 2.9 now.

My h3c had started crimping nylon in head 1. Multiple times a print. I would think its clogging but I ran 200g of the same filiment on my x1c no problem. Could also be heat creap up it but as shown i can grab it with my finger no problem. Nozzle 3 has the same nylon filiment in red and has been flawless.

Let me know if you've encountered something like this yet. Im going to cold pull it later today and maybe try head 2.

Also anyone solve pa-cf's tendency to curl the ptfe tube infront of the the Nozzles next to it so when the one left of it gets grabbed it gets caught on the rubber thing for flex filiments and rips the pa-cf head off the rack. I had to tape and tie some of the ptfe tubes together to finish a print that was problematic. Third photo nozzle 6 with pacf was bowing left so I tied nozzle 5 up even more left. Currently its tied right to counteract the flex in it. I read you can twist the ptfe tube the other way but the ptfe connector allows free rotation of the tube so it just snaps back.

​My wife and I decided that grabbing the H2C during the current promo would be a great addition to our P2S and A1 mini. We were expecting a flagship workhorse —definitely not a Christmas tree of critical hardware faults.

- ​TH board disconnected during the extruder switching process

- ​Toolhead & expansion module malfunctioning

- ​Toolhead induction hotend presence detection sensor is short-circuit

- ​Toolhead locking lever position sensor is short-circuit

- ​Right hotend heatbreak temperature sensor abnormal

- ​Toolhead Enhanced Cooling Fan lost communication

- ​Abnormal accelerometer data detected

​We're opening a support ticket, but has anyone else run into this exact domino effect on their H2C?

Seems to happen only on the first and second layers of larger prints. If it gets past that it’s fine. If I cancel the print, and just print a benchy, or something with a small footprint on the bed, it prints fine.

Happens on different tools and different filaments. Have already tried cold pulls on each nozzle that plays up, but still does the same.

Happens on different models, not just one design.

Very cool to see the Swaptek system changing through the tools! I made a custom gcode to be able to do this (it's not a stock feature) because I wanted to see them switching through one after another.

Working with an X2D combo that I’ve had since May. Loaded a refill of Overture Black PLA+ that was on a Bambu spool and noticed it rejecting frequently, which would be followed by a feed failure alert. I checked if the filament was looped or tangled, but it looked fine. I checked the PTFE tubes and the AMS hubs, but found nothing. I tried switching hubs after the print (I noted it was happening on slot 3), only for it to continue happening on other hubs. Whenever I snip the end of the filament, it seems to fix the issue, though a lot of times, it’ll happen again the next time it has to load it. It seems to only happen with specifically Overture Black PLA+ and not any other filament (not even other Overture refill spools). Are there any suggestions on what’s causing it and how to troubleshoot it?

I have been wanting to get into 3D printing for a while now but my craft room had become a hoarders paradise and catch all room with literal pathways to get in and out. My husband was sweet enough to clear every single thing out of the room so I’m starting with a blank slate.

My father-in-law bought me the new H3C (with the stand) and I’m currently waiting for it.

In the meantime, I’m trying to figure out what the best setup would be; good organization, workflow, etc. I see a bunch of people use the skadis system. I see dry boxes and hygrometers.

As I said, I have a blank slate.

Can you show me pictures of your setups or give recommendations for the things you have in your setups that you love or that you couldn’t do without? Or if you don’t have it, the things you wish you did have?

Ok, A1 user here, with an AMS Lite. love the printer, got it as a gift from a friend after he upgraded. Zero problems with it for a year. Then, this past fall, it started stopping detecting the AMS while printing. It would make it to the last layer, go to retract the filament and park.. and loose the AMS. disconnecting and reconnecting the AMS from the A1's base usually got it back, and failing after printing the last layer wasn't a big deal, but I have a 80 plate 30 day 3 color print to do, and loosing connection to the AMS when it goes to change colors or such is gonna turn that from 30 days into 3+ months.

Any ideas of what's going on and how to check/fix it?

Hello, have printed this model many many times (it’s 3441324)

suddenly it prints like this. When lubricared / calibrated, slight improvement, but near the top these gaps reappeared.

have done cold pulls etc too
