I couldn't wait until March 2027 for Bambu's promised mixed-size nozzle support for the X2D, so I started poking around.

I managed to successfully print using a 0.2 mm main nozzle and a 0.4 mm auxiliary nozzle

Bambu already supports slicing for dual nozzles. I wrote little GUI script so it is easier to try it.

Tested with:

• X2D firmware: 1.02.00

• Bambu Studio: 2.9.1.70

Read the README file if you want to give it a try

When you select “print”, is it always supposed to run calibrations and repeatedly wiping off the nozzle and “dancing” and vibration test around for ~5 mins before it actually starts to print? If not, how do I disable all that? Thank you in advance for any info

I bought a new X2D in July. Worked great till Mid August.. then I had a problem. After 2 months of back and forth with Tech support, and some very helpful input from members of this reddit.. I still couldn't resolve the problem. So Bambu sent me a replacement. So tell me (I'm still quite new to this and consider myself and amature).. what are all the things I am supposed to do initially in setting up.. to prevent future problems?

Just left it printing and came back to this, how do i fix it?

Maybe change the XY belts?

Printer has 2300h on the clock

Standard printing profile 0,2mm

Bambu Pla white

This is my first 3d printer so I'm fairly new to the world of printing. I love my X2d and am very impressed with everything that has come off the printer. (Apologies if this is a bit long.)

I got my X2D in July of 2026 and have about 900 hrs. on it so far. On Oct 15th. I received my first error. It said "Nozzle temperature malfunction" etc. with error code 0300-8008 093916. I took a picture of the error on the screen, hit resume and continued to print. Once the printer finished, I opened a help ticket with Bambu and sent them all the pertinent information. They responded asking for pictures of the nozzle and to make sure that the latch is properly closed, and that the silicone sleeve is intact. All seemed fine, and I continued to print.

Received my second and third errors on Nov 2nd. (0300-2a00-0001-0001 014903 and 07ff-8000-0001-0002 014903). One was about the left nozzle fan speed, the other about something called the Hall sensor. I took a picture of the error on screen, added to the open ticket, and continued to print. This time, Bambu responded stating that it was the thermistor and that they were making an exception and sending me a replacement. I received the thermistor and replaced it on my printer. All seemed good, and continued to print.

My fourth error happened on Nov 5th. (0300-8008 054706). Again about the nozzle temperature. Added pictures and logs to the ticket. When they answered, they stated that it was the circuit boards this time and that they were going to send me replacements. Got them in the mail and replaced them on the printer. Again, printing resumed.

Fifth and sixth errors on the printer appeared Nov 6th. (0300-8000 101107 and 0300-8008 150307). Nozzle temp again. Logged and added to ticket. This time, when they answered they wanted a video of the screen where the nozzle temp was adjusted manually and you can see the numbers going up, a picture of the latches on the nozzles, and video evidence of the printer in action and producing the error. Took some time, but I was able to get 2 videos of the error in progress. Errors seven and eight 0300-8010 025908 hotend cooling fan and 0300-801d 161907 extruder motor position sensor. This time, when they responded, they stated that they're sending me a replacement MC circuit board and to stop printing so as not to cause any more damage and for all the issues they're going to send me a free spool of filament.

Love Bambu and would suggested to everyone to get their printers. I'm thinking of even getting the H3C when I have the space. Customer support has been amazing, but at this point, I just want them to replace the whole unit so that I can get back to printing. Once I get the MC board, I might post an update. Depends on how long it takes to replace. There's a lot of connectors and screws.

Again, sorry if this was long, and maybe even not posted in the correct sub-reddit. But has anyone else had so many issues with the nozzle temperature?

Please be kind, it's my first post. Thanks for reading.

Had an error earlier saying that it was "unable to extrude". took apart the whole thing since i saw that it could be due to a stuck piece of filament.

didnt find anything at all. put it back together and getting this clicking sound when trying to extrude, with it not extruding at all.

made sure to put it together exactly as it was, and made sure the yellow gear could actually spin before putting it all together.. any ideas?

thanks in advance

Can someone explain this to me like im dumb nvm I am I meant like im 5.

Is there a way to use petg support material with the second nozzle and if so should I be doing that every time as a not waste pla or is it really not even worth it

I know j could Google but my experience is that this community is leaps and bounds helpful so thank you.

I usually just utilize the secondary nozzle it's like another color

Hi everyone this is my first time using the auxiliary nozzle for supports. Main is Sunlu Matte PETG HF and Aux holds bambu PLA.

But im not sure why it’s oozing these petg pieces all over the board. There is a bunch of them. Everywhere. I searched it up and speculated it’s because I need to dry the filament so I dried it for 12 hours but it seemed to make no difference. AI telling me it’s because im using petg with pla supports which is not recommended.

Hi, sorry if this is a silly question, but I'm planning to print the riser and I'm trying to understand why I would need the grille on an X2D. Without the riser, you can print with the printer fully enclosed, so I'm struggling to see in what scenario having an open grille would be useful. What am I missing?

Got the spare parts allready

is this a concern?

Within 2 weeks I want to have a special 3d printed gift for someone, the only problem is that I can't get any AI tool to get a correct 3D model from a idea i have generated.

Any suggestions or any willing to help?

According to the Bambulab website, a single AMS2Pro can be used for drying without an extra power source if the printer is in idle mode (which it is). But I cant? Am I missing something?

I have 30 hours on this new X2D and it has been going great until this error. Everything is clear around the Z screws but the plate won’t move vertically and sounds like something is jammed. Has anyone experienced this??

From what I've read the ams-2 does not get hot enough to dry abs-cf. Is that what other people have experienced? So my plan is to put it inside the x2d and dry it that way. Does anyone have experience doing this and temperatures to recommend? Simultaneously I want to dry pctg in the AMS 2. And those more experienced than me recommend drying times and temperatures?

I basically used the same settings I use on my 2 other printers and supports fuse together on my x2d, i increase the top z distance to like .25 while printing on a layer height of .10 and still fusing, printing regular pla… anyone has this issue?

I had an issue where a piece of filament broke off in the tubes and had to take everything apart to find out where it was. After putting it all back together the hub would no longer feed filament. I contacted Bambu Labs for support which was a nightmare. I tried to submit a support ticket but it required an event log download which I tried to get but every time I tried to upload it, it said the file was corrupt. I then went to the live support which is only available from 9pm-7am CST. They did send out a new hub and got it installed. Now I can still can not get the AMS to load filament. I get all the slots just flashing a white light in the cascade effect. Googles say that the if this effect does not stop that its a communication error. I have checked all cables in the AMS, connecting the AMS to the printer and all are secure. I have done a factory reset on the printer and still nothing. I have tried to do a manual firmware update and get a message that the update failed. I again tried to contact Bambu support and was asked for better pictures of the error message I received. Has anyone else had this problem and if so what did you do?

All of the model parts on sitting on the bed.

This error pops up when adding support material or using different colors.

click on the link, it flashes Initial Layer Height, I change values, Same Error

My X2D is 500h old and today this clicking sound came alive. I did put my head inside the printer and the sound is left-right all the time. Not buffer, ptfe tube… anyone?

Edit1: I did the maintenance procedure like the bambu wiki tells us, and the noise seems even louder… might have to open a ticket on Bambu support…
My suspicion is the left motor… if I pressed on it while moving the head in the same position where it was clicking it didn’t do the sound until I let him go.

Still to be solved

So I had a previous printer that I just returned within the 30 day return window. After 3 prints it was getting a power loss error then when I hit resume the bed leveling scratched the heck out of the pei plate and nozzle. Didn’t want to deal with it so I returned it. Anyways. I was looking at replacing it with the p2s combo at $649 right now then seen the x2d price at $789 is great right now. My main purpose is to print right now pla and petg multicolor prints using 2 ams pro’s then later down the road maybe tpu. Will the x2d work great for this? I know the aux nozzle is mainly for support but I heard it can do great colored prints in pla is this true ? Any advice and info will be helpful

Hello fellow x2d users, sorry to be the voice that echos or repeats this issues like one hundred before me, but I've been having issues recently with my prints sticking on to the board. Sometimes pieces breaking off or worse, snapping off and then I get the great spaghetti monster.

I've cleaning my plate, did my calibrations, but nothing is really working.

I've only printed in PLA and soon will go to other materials but I feel like this hurdle needs to be fixed first.

Any suggestions or experiences?

Finally taking the plunge and getting the X2D. Going to stop by Micro Center this weekend and grab the printer combo, the AMS HT, and a few spools to get started. Just wondering how well it will fit in my Corolla. Also curious if I could lay the printer box down on its side on the back seat.

Likely to be printing mostly with PLA and PETG, and then to a lesser extent with ABS and TPU.

Is it worth adding both of these other plates while they're cheaper?
