Bambu Lab X1 Carbon

[...] The push for the S0 mac-style standby made my 11th gen X1 carbon basically unusable for me in Linux. The standby battery life is so bad, it will burn through half the battery overnight with the lid closed. The battery life actually seems better when using the laptop opposed to standby. [...] I still have my 4th gen X1 carbon, it was an amazing machine for 8 years and I really thought I'd get another 8-year laptop buying the latest X1, but now it sits off and only comes out for specific uses. [...]

[...] At the same time the X1c will print as expected (almost flawlessly) using the same spool of material back to back. [...] 2026-09-1811-30-441920×1049 528 KB I have been using the x1c for 1.5yrs. [...]

[...] 1) Bambu Labs X1 Carbon (X1C) The X1C was my first printer, and now I have two. My research led me to the Bambu X1C as it was the most automated plug and play printer without much hassle. [...] I've been very happy my printer, I got a 2nd a few months later. [...] 2) 3d Design is through 3D Software. [...]

My X1C’s micro SD card slot has finally given up completely. [...] The screen unit and touch functionality still work perfectly fine, and I can still print over Wi-Fi/LAN without issue thanks to the onboard memory, but losing the slot means no timelapses, video recording, or local log saving. [...] Has anyone dealt with this failure on an older X1C? [...]

IMO the ThinkPad brand died after IBM sold its PC division. Lenovo has kept it alive because it is a cash cow, but the machines have shoddy build quality and are ludicrously overpriced. My previous X1 Extreme Gen 1 (2018) had annoying coil whine and screen backlight bleed. One of the key caps broke off after a couple of years. Eventually I ended up doing a full keyboard and battery replacement. My current X1 Carbon Gen 13 is nice and light, has no coil whine, but it's still made from cheap plastic. [...] At this point the only thing keeping me on ThinkPads is the TrackPoint, but since trackpads are decent on Linux nowadays, I think I'm ready to finally ditch the brand. [...] Frameworks seem nice, but I've read many issues about their build quality, and they're not cheap either.

I’m getting patches of what looks like poor bed adhesion on my X1 Carbon with a 0.4 mm nozzle. [...] Photos attached. [...]

[...] If you want help interpreting the tower, upload a photo and I can point to the likely best temperature. [...]

quick update I switched to .4 default nozzle. [...]

[...] Where I slowed the speeds down to less than 30mm/s for everything… then made a test print, it looked pretty good, Since this was just a quick test I left wall thicknesses to default of 2. [...] FWIW, X1C does not have an issue printing this part/material will full solid part… with a .4 nozzle of course. The price of x2d looked too good to be true. [...] x1c spoiled me I guess. Perhaps I am going to have to pull the trigger on a H2… I just want rock solid reliability printing the higher end materials. [...]

X1C was a great machine at time of release, no doubt about that. But Bambu did leave it at a high price point for too long. Once P1P was being sold for $400 and P1S for $550 (If I’m not mistaken), there was no reason to sell X1C for over $1000. Right now Bambu has X2D, that at least in theory should have all the abilities of X1C, in addition to a double-nozzle, and costs almost half. So X1C has no place (especially at it’s price point) in the Bambu lineup anymore…

I’m a proud owner and user of the legendary X1C and I find it strange that for quite some time now, there seems to be no more discussions or new topics in the X1C section (actually, in the entire X1 section). [...]

[...] I’ve been a big Lenovo fan, settled on the X1 carbon. [...] The USB-C port broke on both G6 and G9 models. [...] Unfortunately the ports are soldered directly on the motherboard making it difficult to fix(should be a small separate board for easy replacement). [...]

I'm a big trackpoint fan and proud owner of an X1 Carbon Gen 7 Thinkpad, but I would not recommend this keyboard. The build quality is pretty bad. [...] If Lenovo were to replace the cheap feeling plastic casing for alumninum, it would be a game changer. I'm hoping the new framework keyboard can become my new daily driver, replacing the trackpoint keyboards I currently use.

[...] I had to use a mac for 2 years for a job in between but other than that, T series, Two X series machines (Which were my favourite) and finally, now an X1 carbon. [...] The battery dropped to 75% of max charge in a month and it heats up quite quickly. [...]

Eh cheaper than now for sure. I got my old G1 X1 Carbon for somewhere between 900 and 1100 from memory. [...] (I think that was 1600 dollars partner pricing - charity discount - volume discount (hopped on an order for 12 already identical already going through) - tax incentives) The cheapest Gen 13 Carbon currently available is 2600 in the same currency, and that's already discounted by 9%, and has a shittier OS (Ships with Home edition instead of Pro), I doubt that would get below 2200 even with partner/channel pricing. If you add "Winflation" that is, Windows 7/8 running perfectly smoothly on the Gen 1 with 8 Gig of memory, the replacement thinkpad being one that runs Windows 11 comfortably would be the $3150 in the same money, for its 32GB memory. [...]

I've had the same experience. My IBM ThinkPads had great keyboards. [...] Oh, and I forgot to mention the most annoying issue of all: the TrackPoint still drifts on every modern ThinkPad! [...] I've had it on my 2018 X1 Extreme, and now on this 2025 X1 Carbon. [...]

[...] I retired 3 ultimaker S7s for 2 X1 Carbons and haven’t looked back. [...]

I've since upped to 1.4mm walls which my X1C seems to be handling ok. [...] I'd say I'm not doing too badly considering there's no definitive instructions on how to set it up on my X1C. I've had to piece info together to get it done.

[...] In my case, after installing it, my X1C repeatedly got stuck at “Preparing AMS” and was unable to start a print. [...] I updated my X1Cs and haven’t been having any problems. [...]

It could just be the X1C being EOL caused them to just decide “no”. [...] More dev time for other projects and no money wasted on one that doesn’t matter. It wouldn’t be the first time someone decided to call a project “impossible” just because they didn’t want to do it - especially if it helps point users at new replacement models.

Im going to be selling my X1 Carbon if I get a new H3C, but im having a hard time deciding what price to sell it at. [...] What would be the best price to start it at, and are there any better sites to sell on?

Using an X1c. [...] My X1c has always been right on the mark. [...] I’ve changed filament, different brands, build plates, hot ends, drives and still get the same results. The build pates are clean and glue stick added. [...]

My X1C isn’t prompting me to upgrade firmware so I assume I’m at the most recent version for printer and AMS units. [...] Anyway, my X1C prints fine on (presumably) the latest firmware versions. [...] On the downside part, always a downside with firmware updates. [...] Most firmware updating now can be recovered if there is a power glitch but I don’t know that’s true with Bambu printers. [...] And this was a while back but there was a firmware update that caught a bunch of folks out because it discovered hardware issues in the printer main board and Bambu had to send out a few replacement boards to get people working again. [...]

[...] Problem with that is Bambu Studio just crashes when trying to open gcode… I have never been able to open Gcode in Bambu Studio. [...] You should have have robust and comprehensive profiles, and options in the software. [...]

I got the same experience as @lkraus . At least once my initial X1 had been replaced under warranty. [...] When I got my initial X1, I had high hopes for all kinds of calibration options using single layer patterns and the Lidar based on physical principles at the nozzle. [...]

I’ve had my X2D for a month or so now and I’m loving it in general but I can’t help but notice that the print times for the 0.16mm Standard preset in Bambu Studio are slower than the 0.16mm Optimal preset for the X1C. The below comparison shows the exact same .stl being printed on X1C (left) and X2D (right) with 10% infill. [...] There is no ‘0.16mm Optimal’ preset for the X2D and vice versa no ‘0.16mm Standard’ preset for the X1C. [...] Am I going to encounter drawbacks in quality if I set these speed settings to match my X1C?

I know that many Bambu Lab X1 Carbon owners have been hoping that the “Drying While Printing” feature for the AMS 2 Pro and AMS HT would eventually become available on the X1C as well. I therefore asked Bambu Lab Support directly whether there is any hope that this feature could be added to the X1C through a future firmware update. [...] This hardware capability is apparently not present in the current X1 Carbon. Therefore, according to Bambu Lab, this feature cannot be implemented through a firmware update alone. [...] Your proactive engagement with the firmware verification process is highly valued, and our R&D team is actively analyzing the data you provided to ensure a stable future release for the X1 Carbon. Regarding your inquiry about the Drying While Printing functionality for the X1 Carbon, we would like to clarify that this specific feature requires specialized hardware integration within the printer architecture to operate effectively and safely. Because it relies on hardware capabilities that are not present in the current X1 Carbon design, this function cannot be implemented through a firmware update alone. [...]

[...] image1782×1569 377 KB And, of course, with some tests such as retraction speed, there is no convenient preview mode that clearly displays the changing retraction-speed values. [...]

Believe it or not, I still think you have a build plate contamination issue. [...] First, some contaminants such as silicone-based lubricants can be extremely difficult to remove from surfaces, to the point where if they’ve transferred to the actual heat bed (from flipping the build plate) they’ll just keep re-contaminating the build plate even if you’ve thoroughly cleaned it. Unfortunately the linear rails sitting directly above the build plate are lubricated with these exact compounds, and very small amounts can be shed onto the plate. [...]

That result would have me looking pretty hard at extrusion/flow calibration, especially since slowing everything below 30 mm/s materially improved the print. [...]

[...] In the example shown, you’re comparing the X2D with a 0.6 mm HF nozzle against the X1C with a 0.4 mm nozzle. [...] Since the same spool prints correctly on the X1C, you’ve done a good job ruling out wet filament, but I don’t think the test yet isolates the X2D itself. [...]

Leckiestein has a bunch of really great X1C optimizations including wiping subroutines and a really clever way of controlling them. Might wanna give them a go rather than reinventing the wheel yourself. Search for “Steinwipe”.

long-life and durable keyboards It wasn't that long ago they had terrible keyboard lifespans which could be a death knell for the laptop, and overheating CPUs which limited performance way behind spec. [...] Alas, they aren't ahead in many other dimensions; my Fedora X1 Carbon is my strong preference over my M4 macbook pro and a large part of that is the basic usability of the system and window manager (sway), which is something Apple will never match until we meaningfully switch interaction paradigms.

The X2d fans are not very good IMO for hot boxes. They do fine printing PLA, but I also did not have very good ASA luck, found the hacks re: fan gcode, and decided to just do my ASA on the Qidi lol. If you scrape around the forums here you can find others who have done fan mods and fan gcode overrides to get it behaving better.

Current-gen X1 Carbons are sold with 400 or 500 nit IPS displays. I have complaints with nearly every other aspect of the ThinkPad---even the universally praised keyboard---but the display has been stellar.

X1E user here Was actually just considering making a post seeing if anyone "up"graded from the X1E to another printer and what their thoughts have been. The X1E seems to print PAHT-CF like PLA and has been unstoppable…except for when I accidentally tried to swap nozzle with printer still powered on… There was recently a firmware release that claimed to fix the pesky “user information expired” error when powering up printer, I was so excited as this has been my only gripe, except it still happens

the X1C is a proven platform, runs for ages, but with it being EOL and a number of newer, cheaper options available to new users the only folks that are using them are legacy users who know what they are doing and are not jumping on the forums to seek advice… that’s just my take I’m still running an X1C and will continue to do so as long as it will go.. [...] If something beyond a simple replacement were to fail on this thing I’m not sure that I would spend the effort to get it running.. but with only 5k hours on it I think I just got it broken in lol

X1C owners simply do not have much to talk about. Most have had the printer for a while and are familiar with its operation, features, capabilities, and limitations. It’s pretty reliable, so there are few faults to discuss; the solutions for the few that it does have are well known.

I use my X1C all the time - it’s still seeing similar print hours to my H2C. I don’t think we’ll see much in the way of development or modifications going forward - if I was going to be developing something new for the X1C I’m definitionally targeting a shrinking audience - there are never going to be as many X1Cs out there as there are today. I’d like to see development efforts shift to the H2 series - there’s so much unrealized potential in that platform.

Still got mine and use it all the time. No issues so far. It’s in great shape and just cranks out prints.

[...] I have been seeing a lot of X1Cs on facebook marketplace in the past year.

Yeah I was an X1 Carbon True Believer for a while but I cant justify their current prices. It used to be 1200 bucks or so cheaper than the equivalent macbook (probably saying as much will piss off the "Thinkpads were never cheap weridos but thats fine)

My x1 carbon gave me nothing but trouble from the beginning. I couldn't even move it too fast lest I risked it locking up. Additionally, my wrist strain got considerably better after ditching it for a comparably priced M2 that blows it out of the water in every conceivable category.

[...] Samsung doesn't have those issues, but it lags between announcing and shipping. [...] Lenovo announces and then nothing - they have announced x1 carbon gen 14 in january.. [...] This is Tim Cook's value and it can't be denied.

I have 2 thoughts. On my X1C I had to install a ptfe guide on the tool head or I would get the same thing you are. Also, on a friend’s his filament sensor in the tool head was bad preventing the filament from loading all the way.

Yeah, my sister and I got the Bambu Lab X1 Carbon! We didn't print anything fancy or whatever yet but we definitely printed a bunch of stuff, our printer barely gets any longer breaks and most prints were pretty successful. I might post a couple pics soon.

I've had really good luck with the Bambu Lab X1 Carbon. I've even sent projects to the printer from MakerWorld on my phone

Alright, I’m now experiencing the issue in the title - the X1C is attempting to load filament from a singular AMS H/T, but fails to do so. [...]

Hi everyone, since updating my X1C to firmware 01.12.00.00, I’ve been having an issue with the AMS. [...] I had the same issue before and was able to temporarily fix it by disconnecting and reconnecting the AMS cable several times. [...]

At least for me, Adaptive Pressure Advance on the X1C made it print way worse that with regular pressure advance.
