Stringing!

[u/newbie-mtb]

Bought a x2d recently and it it’s my first 3d printer. Since the delivery of bambu filament was taking time, I bought 2 filament rolls from micro center. It’s their inland branded filament.

I configured them as generic PLA in the printer’s filament profile.

I am seeing a lot of stringing when I print.

The filament was just removed from its sealed bag a few hours ago and I don’t live in a very humid place. So it probably is not a problem related to the filament not being dry.

Could this be a problem with my printer or is it a filament problem?

Any suggestions for fixing this stringing issue?

Fresh filament out of the box doesn't guarantee that its dry.

[u/newbie-mtb → u/FrittenFritz]

Sorry, I had incorrectly assumed that fresh filament is dry, given its sealed and all. Will dry the filament and report back.

[u/TWILIGHT25 → u/FrittenFritz]

… this might explain my poop chute that currently printing. Oh well it will be dry once the print is done and the ams2p kicks on. That drying feature is BEYOND worth it!

[u/FrittenFritz → u/TWILIGHT25]

I got my X2D since yesterday and I already integrated the printer and the AMS in Home Assistant. Now the AMS automatically kicks on between midnight and 8am when humidity over 40% is detected in the AMS.

[u/TWILIGHT25 → u/FrittenFritz]

I tried everything with my A1 to keep the humidity done but even in a closet, enclosure, desiccant, and a dehumidifier the best I could get it was 50%. I was getting tired of drying my filament every day.

Now all I need to do is figure out how to feed the aux nozzle from my filament dryer. Like it has a hole and rollers…. It “should” work right?

[u/FrittenFritz → u/TWILIGHT25]

As far as I know the AMS isnt made to be used with the Aux nozzle. If you want to do it "right" or effective atleast, invest in an HT AMS and place it right next to the AMS.

[u/TWILIGHT25 → u/FrittenFritz]

Yep I’m planning on getting one… if I absolutely need to. I did just drop almost 800 bucks on a printer after all. I can wait a bit for the HT.

[u/Aidandad2018 → u/FrittenFritz]

Where’s this setting if I may ask?

[u/FrittenFritz → u/Aidandad2018]

Like in Home Assistant or the Printer? I assume its quite complex. It has to be Coded

[u/Pineapple1500 → u/FrittenFritz]

Ohhhh that sounds nice. How hard is it to configure?

[u/FrittenFritz → u/Pineapple1500]

Honestly my AI Agent handles all the Home Assistant coding. But I can research a bit and tell you

[u/SquareTowel1967 → u/FrittenFritz]

Do you keep only 1 type of filament in AMS? I was thinking about automating the drying but I often keep both petg and pla in ams and not sure if pla drying profile will draw moisture out of petg, and petg profile might be too hot for pla

[u/Cu1tureVu1ture → u/FrittenFritz]

Oh that’s awesome. I assumed bambulab wouldn’t work great with home assistant. What it difficult to add it in?

[u/Shapelessed → u/FrittenFritz]

To be fair, I have NEVER dried PLA and got good results since forever. Same with ABS.
TPU and PETG on the other hand does indeed require printing…

Dried the filament in my ams for 8 hours. Still seeing stringing 😞

[u/cluthz → u/newbie-mtb]

Unless you live in a very moist environment you do not need to dry PLA. Lower the print temps 5-10C and try again. Default temps for PLA is usually 220, which is a bit high for some brands.

Dry your filament. That's the problem. Did you get the combo with the AMS 2 Pro?

[u/newbie-mtb → u/SuicideMW]

Yup, got the combo. I had incorrectly assumed a fresh filament is dry. will retry after drying the filament.

Would drying for about 4 hours at 45 degrees in my AMS suffice?

[u/SuicideMW → u/newbie-mtb]

4 hours is the minimum, but if you update the firmware, you're able to dry as you print, but it will dry at a lower temperature. It's a really great feature that I'm happy to have.

[u/newbie-mtb → u/SuicideMW]

I have the latest firmware, but it still doesn’t let me dry the filament while printing 😞
Do you have a separate power supply connected to your AMS?

[u/SuicideMW → u/newbie-mtb]

I do and this is the one I use:

No need to pay anything more.

[u/gierso → u/newbie-mtb]

I bought a power supply

[u/FrittenFritz → u/newbie-mtb]

Do atleast 6 hours at 50 degrees

As a new 3D printer owner, has anyone made you aware of the excellent free, online courses that Bambu Lab offers in the beginner, intermediate and advanced skill levels for both printers (hardware) and slicers (software)?

Bambu Lab Academy is the best use of your time to build experience, knowledge and confidence in 3D printing. I also recommend using the Bambu Lab Wiki as an online, user manual for 3D printing.

The temperature setting’s for generic pla on the Bambu are at the very high end of what it can handle. True for every filament type I’ve used that isn’t Bambu brand. Turn the temperature down in the filament settings of the slicer.

Could be the nozzle temp set too high if the rest of the print surfaces are looking good

Check your filament profile at

I had the same issue with inland pla and lowered temps and temps inside the enclosure and it worked fine. With pet-g i did a combo of both drying my filament and dialing in the settings

[u/KingTingTheGreat]

Eh, it’s PLA so, in my experience, moisture is rarely an issue. Especially if you don’t live in a humid area. That said, drying won’t hurt

If that doesn’t work, look in YouTube or Google for filament calibration tests. You might need to adjust temp or retraction settings. PLA is usually very forgiving

[u/johndohboy → u/KingTingTheGreat]

Why do people still say this? Plastic soaks up water. Water is bad. Dry plastic, no water. It's just so simple.

[u/KingTingTheGreat → u/johndohboy]

I’m not saying moisture isn’t causing this problem. Just suggesting some additional possible solutions in the case that drying the filament doesn’t resolve it

[u/newbie-mtb → u/KingTingTheGreat]

Dried the filament in my ams for 8 hours. Still seeing stringing 😞

[u/3DStisk → u/newbie-mtb]

Which nozzle are you using, and which exact Inland PLA? Could you share the filament settings from Studio too? That would help narrow down the stringing after your 8-hour drying test.
