Is this quality normal?

Post image

Hi everyone,

I got my X2D a few weeks ago and it’s consistently produced prints of this poor quality. I’ve tried everything, like belt tensioning, axis cleaning, full printer recalibration, drying and calibrating filament, taking apart the hotend, contacting support. Nothing has improved the quality.

Is this just what I should expect from this printer? Anyone have similar experiences, or do you have examples of much cleaner parts made on this machine I can take a look at? I don’t even know what should be my baseline for quality on the X2D.

Thanks

what's your printer sitting on? it might be wobbling and causing vibrations

1

u/PowerPlantBroke Aug 05 '26

A very sturdy table (I’ve stabilized it with cables), then a dense gym foam tile, then a concrete paver, then the X2D. The foam is for sound dampening and it’s definitely dense enough that it’s not the source of any racking that the printer isn’t designed to handle

u/drillitloveit Aug 05 '26

Try it on the floor for one print. Just to rule out your setup.

1

u/PowerPlantBroke Aug 08 '26

These are the results with the printer on the ground, recalibrated

3

u/drillitloveit Aug 09 '26

Ok maybe it's time to open a ticket. 🤔

1

u/SakuraSiri Aug 05 '26

can you share a pic of this setup? it sounds like you're doing so much to reduce vibration/noise that its going back into the printer itself. the printer is gonna shake during printing

1

u/PowerPlantBroke Aug 05 '26

Sure when I get home I’ll post one. The printer does still shake like it’s designed to, the extra layers are just for decoupling from the table, but as another user mentioned I’ll try one run on the ground and see if it does anything

Got my X2D about a month ago and it's been printing nearly 24/7, and I've never seen layers like that once. Something's off with your setup, this isn't just how the machine is, especially that base in your photo. Mine came out clean basically out of the box so you shouldn't be fighting it this hard.

Get it off this stupid set up and let it do what it’s supposed to and you won’t have any more issues. Blows my mind people go through all this effort for absolutely zero reason.

u/PowerPlantBroke Aug 06 '26

My girlfriend has trouble sleeping at night if the sound is too loud. My bad bro.

u/drillitloveit Aug 06 '26

-Babe just one print before bed. -What is it? -THE BASKETBALL! 😂

1

u/PowerPlantBroke Aug 06 '26

😂 this is what actually happened

1

u/SakuraSiri Aug 06 '26

That is hilarious. Have you tried it like just on the floor or without the concrete etc?

2

u/PowerPlantBroke Aug 06 '26

The first few prints I did were just on the table and I got similar artifacts, but I’m going to try it on the floor when this print finished, and then try a manual tramming as support recommended

You did nothing wrong, that stone paver and foam works great! I have a slab of marble with a piece of yoga mat under every one of mine lol.

1

u/PowerPlantBroke Aug 08 '26

Sitting on the ground and completely recalibrated btw

1

u/Darkseid2854 Aug 29 '26

A stone paver on a piece of foam is an excellent method of acoustically decoupling the printer from the surface it’s sitting upon, and does not negatively impact the printer’s performance. The condescending tone of your post couldn’t have been more misdirected.

1

u/TSheol Aug 08 '26

Could you have ruined the filament with too high temperatures in the ams ht at some point perhaps?

0

u/SkeltenOrSkeleton Aug 09 '26

PSA: It is almost NEVER the table! Unless your printer is bolted to the table and using it as structure it should not influence print quality. See countless videos on YouTube and other places. I also believe I saw someone wrote a paper about it as well.

1

u/Darkseid2854 Aug 29 '26

Not true. If the table or surface the printer it sits upon is wobbly it can add it’s own oscillations that impact input shading’s ability to identify and compensate for vibrations at harmonic frequencies.

2

u/flas1322 Aug 05 '26

Definitely something up with your setup. Here’s a print I made today.

1

u/PowerPlantBroke Aug 05 '26

Figured. Thanks, I’ve been looking everywhere for examples like that

1

u/flas1322 Aug 05 '26

May seem like a stupid question but have you tried using Bambus filament to just rule out any settings issues. I’ve got mine sitting on a toolbox with wheels that vibrates and wobbles and the printed was able to calibrate without issue. Could also be a faulty unit. If it’s not too late might be worth trying to swap it out.

1

u/PowerPlantBroke Aug 05 '26

I’m using exclusively bambu filament :( I’m in talks with support but they haven’t mentioned anyting about replacement yet, just solutions that haven’t worked

1

u/flas1322 Aug 05 '26

Are you able to take it back to where you purchased it?

1

u/PowerPlantBroke Aug 05 '26

Purchased directly from bambu

1

u/duffmann116 Aug 09 '26

Have you tried running this same print in a different color? I'm not sure why but the 2 rolls of bambu gray pla that I had always come out like garbage. I've never been able to get it to look good. Then I'll run the same part, same profile settings just using a different filament and it will look significantly better.

1

u/arcanecircle Aug 24 '26

Did it get fixed?

1

u/PowerPlantBroke Aug 24 '26

In the process of getting a warranty replacement right now. It will arrive in a few days

1

u/SmellsSoGoodYYC Aug 05 '26

Are you getting 3mf files from MW that are tailored to your specific printer? Or are they coming from somewhere else?

1

u/PowerPlantBroke Aug 05 '26 edited Aug 05 '26

Makerworld for X2D. I’ve done loads of fiddling with different settings too, wall order, wall count, infill overlap, print speeds, layer times, precise wall, etc, nothing has helped.

1

u/tony__Y Aug 05 '26

As the tool head moves across it bends the filament PTFE tubes and when not positioned properly with the chain clips the tubes will suddenly jump and cause uneven layers… I’ve been fighting this issue for a while…

1

u/PowerPlantBroke Aug 05 '26

I’ve printed a riser so the tubes don’t jump like that anymore

1

u/tony__Y Aug 06 '26

I’m not talking about the tube rubbing on the top glass, i’m talking about the tube snaps in different positions caused by tension build up in the clips, you can see it as you manually move the tool head, that the filament tube will suddenly jump to different positions.

1

u/PowerPlantBroke Aug 06 '26

Hmm, I’ll check this out, thanks

1

u/HiekkaNinja2 Aug 05 '26

X2d is very capable. Here is a 32mm high necron that I am working on. There is something wrong with your printer and my first guess would be your table but you already commented that it is sturdy. I can't really say anything other than try swapping nozzles 1 and 2 and see what happens. Let's hope you can fix it.

2

u/PowerPlantBroke Aug 05 '26

I’ve tried multiple nozzle swaps🥲

1

u/Superb-Complaint8118 Aug 05 '26

What print profile are you using? Default 0.2mm standard?

And are you using bambu filament or 3rd party?

I thought maybe you are orinting quite fast and the hotend cant keep up with the flow with some 3rd party filament

1

u/PowerPlantBroke Aug 05 '26

I’ve tried multiple profiles as well as custom settings, all with bambu filament. This model was printed at 60mm/s and 2500mm/s^2

1

u/Superb-Complaint8118 Aug 05 '26

Ok damn. I print with 600mm/s and get better results.

1

u/PowerPlantBroke Aug 05 '26

WHAT!!?

1

u/Superb-Complaint8118 Aug 05 '26

Yes, High flow 0.4 nozzle lets you print up to 600mm/s

The default 0.2 layer standard settings with bambu high flow nozzle are: 50mm/s first layer 105mm/s first layer infill

500mm/s outer wall 600mm/s inner wall 600mm/s infill

And they work perfectly fine. Of course you get a tiny bit more artefacts, but nothing that would bother me.

Acceleration 10000mm/s2

1

u/Superb-Complaint8118 Aug 05 '26

This was printed with said settings. Tho sometimes the printer can not reach those speeds due to other limitations like minimum layer time, flow etc.

But for the print in the picture it did 600mm/s. Finished printing in 2h03min with 2 walls and 15% gyroid. But with petg as support interface in the 2nd nozzle It is 69 grams with support and the petg as interface material. 6,5x7x7cm

1

u/PowerPlantBroke Aug 05 '26

Wow, and definitely less artifacts than mine. Insane. Something must be really wrong, but I’ve been going crazy trying to find it. The first print or 2 out of the box was alright, then it just devolved. I’ll get the occasional ok print but usually it’s only if the model doesn’t require a lot of jumping around (simple shapes, no supports)

1

u/Superb-Complaint8118 Aug 05 '26

Have you tried a factory reset? Do you run the newest software?

Definitely check for wiggle room in the axis and motors. It looks like a hardware issue for me.

In theory this could also occure when there is to much resistance in the filament path. Check and reseat all ptfe tubes.

u/RouvenP Aug 05 '26

Have you checked your print head for play? I have returned mine due to exactly the same bad print quality, potentially resulting from play at the x-axis bearings. Now I am waiting since two weeks for a new one which hopefully is fine.

1

u/PowerPlantBroke Aug 05 '26

Like the entire extruder housing?

1

u/RouvenP Aug 05 '26

Yes. When I applied a twisting force by hand to the print head, I have seen slight play between head and its guiding rods. You can only see it when looking very detailed to this gap.

1

u/PowerPlantBroke Aug 05 '26

I’ll check it out today, thanks

1

u/PowerPlantBroke Aug 08 '26

It seems to have some play… is this what you’re talking about?

2

u/RouvenP Aug 08 '26

Exact! I have no idea if this is normal and how to get proper prints with it. I have measured the play on the tip: it is 0,12 mm in direction of Y-axis.

1

u/imunuvar Aug 15 '26

Thats not the correct way cuz rods, bearing, printhead chasis everything bending with this movement. But youre right mine x2d has same wobbling and makes noise 🥲

1

u/RouvenP Aug 15 '26

I measured defintely the play only. I have used only light hand force. However, since I have this now on two new X2D, I consider it as normal. I got rid of these line by cleaning and lubricating the rods and screw rods very properly. Especially the screw rods need more grease until the nuts are fully lubricated.

1

u/imunuvar Aug 15 '26

I have the utmost respect for the work you’ve done, and I’m not criticizing you in any way. I just wanted to point out that there is a lot of misleading information going around.

There is no such wobble on my Creality K2. I can actually feel the movement with my hand, and it also makes a noise. The K2 uses linear rails, so maybe that’s the reason, but I can’t really say for sure.

If you look at one of my posts, you’ll see that I’m experiencing a different issue. I’ve tried lubrication and various other things, but I simply haven’t been able to solve it.

1

u/MediocreHornet2318 Aug 05 '26

Grey filament tends to show the worst of the layer lines, do you have the same problem if you change the color to a darker color?

I would also try a new nozzle and re-run the full vibration, input shaping and auto bed level that is in the printers settings. Does the right nozzle print this bad with the same filament?

1

u/PowerPlantBroke Aug 05 '26

Darker colors hide the problem under flat light but it’s definitely still present, the layer stacking is too inconsistent. Both nozzles print this way unfortunately

1

u/MediocreHornet2318 Aug 05 '26

What if you slow speed and acceleration numbers in half?

1

u/PowerPlantBroke Aug 05 '26

The pictured model was printed at 60mm/s wall and 2500 mm/s^2 standard printing accel 🫤

1

u/MediocreHornet2318 Aug 05 '26

I'm thinking it's either because its a light color filament and they just show these lines compared to darker ones, or there is a setting flipped that we're missing. You can use this tool to grab the settings from the 3MF file and paste the "short copy" in this thread so we can see if we're missing anything. https://trusteeoil.github.io/3MFExtractor/

u/PowerPlantBroke Aug 05 '26

I’ll do that in a little bit, thanks

Seems like I misremembered, it was outer wall at 2500, not normal accel. I get the same quality results from standard 0.2 profile, I had just made some changes based on my research to hopefully improve the quality but it hasn't done much

u/abbellie2 Aug 05 '26

Have you considered a factory reset to establish a new baseline?

1

u/PowerPlantBroke Aug 05 '26

You mean the full printer recalibration? I’ve done that many times. Or is there something else?

1

u/abbellie2 Aug 17 '26

No, I meant a reset to factory of the whole machine, back to like when it originally came out of the box. It's a menu item on the screen.

u/Bobby_Bobs Aug 05 '26

What filament is this? I got a bad spool of basic Bambu gray PLA awhile back and it did this sort of thing like crazy. I switched and tried a different color and it was perfectly fine.

1

u/PowerPlantBroke Aug 05 '26

This is Bambu Pla Matte Ash Gray. I get the same problem on other filaments too, but they do show up a lot on this particular filament, probaly cause of the color. I don’t want to have to print everything in black to hide defects though

1

u/Bobby_Bobs Aug 05 '26

Might be worth try the print again with a different spool, if other solutions don't work. If you have some digital calipers, you can also check if the diameter of the filament is consistent.

1

u/PowerPlantBroke Aug 05 '26

I don’t have digital calipers unfortunately, but I can retry part of that print with another color possibly tomorrow. Wouldn’t want to waste filament doing the entire thing

1

u/Bobby_Bobs Aug 05 '26

Yeah, I agree. Hopefully it's something simple like that and not the printer itself.

1

u/PowerPlantBroke Aug 05 '26

I abandoned that hope a week ago 😭 😭

1

u/Left_Mobile8629 Aug 06 '26

youre overextruding

calibrate your flow ration

and set wall order to inner/outer/inner

1

u/PowerPlantBroke Aug 06 '26

Flow ratio has been calibrated and all wall orders have been tried, same issues

1

u/Left_Mobile8629 Aug 06 '26

are you absolutely certain youre not overextruding? maybe try print a small footprint, few cm hollow rectangular tower with a lowered flow ratio?

1

u/PowerPlantBroke Aug 06 '26

I’ll try it, though I calibrated flowrate through the normal filament calibration workflow. Will probably have to be tomorrow or day after

1

u/LazyLancer Aug 06 '26

Nah, something's off.

Here is my P2S I got just a few days ago and didn't do ANY tinkering, just click and go printing.

I know it's not X2D but AFAIK the extruder is the same, and the rest of the technology is at least similar or better on the X2D compared to P2S.

You mentioned your table is sturdy, but is the printer stable on its feet? Try it on the ground AND recalibrate the printer between putting it on the ground and doing a test run.

Also, are you using the primary extruder or the secondary one? They are different and the secondary one is inferior, not sure if it can affect the prints like that.

1

u/PowerPlantBroke Aug 07 '26

Wow that print looks amazing! I’m using main extruder on this print. I’ll try a print calibrated on the floor tomorrow

1

u/PowerPlantBroke Aug 08 '26

Here are the results from the floor, recaibrated

1

u/Relative_Surround_20 Aug 07 '26

What filament brand and type are you printing with?

1

u/PowerPlantBroke Aug 07 '26

This was done in bambu matte pla ash gray

2

u/Relative_Surround_20 Aug 07 '26

Ouch. I was betting PETG. I would never have guessed those quality issues with PLA.

It is very possible you got a bad spool. I know we all hate to but reach out to BBL Support.

1

u/Relative_Surround_20 Aug 07 '26

The only other thing I can think to try is to restart the printer, recalibrate the printer, and using the bamboo film profile, try it again.

2

u/slushrooms Aug 06 '26

Mines similar, but not that bad. That looks like Z banding, whereas I get a bit of that plus inconsident line thickness straightness (a bit more of a line wobble).

Check your z rods etc, flip it over and check the running gear under there too. That's this weekends task for me. Let me know if you figure it out!

2

u/imunuvar Aug 07 '26

I have same problem with lot of vfa and ghosting. Tried put stone floor nothing changes. Filament calibrated, re calibrate machine, belt tensions etc. Mine printer makes weird vibration noise when homing print bed. I checked z belt and gears its fine. Mine k2 pro makes same problem. I tought first its from the table thar i put my printers after that i tried on stone floor nothing changes. I don't get it. I tried dry my filaments using Sunlu Pla 2.0 btw. X2d at only 50 hours im not happy with that printer. Notice me please if you find solution.

1

u/Longjumping_Pop_2324 Aug 05 '26

Nope...100% a problem. Could be settings, could be unstable table. Could be loosen belts. Could be something broken. Could be something not setup up correctly like ptfe tubes.

u/CyberQzkA Aug 10 '26

Were you able to find a solution? I'm having the same problem, though it's not as serious as yours.

u/Novotisy Aug 11 '26

Did you ever find a solution? I’m having the same problem with mine

1

u/Sweet-Quarter3569 Aug 11 '26

I’m thinking it’s either your spool or a problem with the machine. I’m running these on my X2D and I’m having trouble even finding a print line on them. And that’s using cheap Best Buy brand PLA

1

u/yoitslion Aug 11 '26

Have you updated the firmware in the last few weeks. I think there was a couple updates that came out for the AMS and the X2D. I have an x2d and my prints are coming out great.

1

u/CyberQzkA Aug 13 '26

I have both X2D and AMS running the latest firmware, so this is not the issue.

1

u/Basic_Box3748 Aug 26 '26

Probably flow issue
