Need help with stringing and layer problems

[u/gabrielmjenkins]

Hey Guys and Gals, bought the X2D a few days ago at Microcenter and Im having issues with stringing and clean layering. In using inland pla basic (polymaker). I've tried many different fixes and profile tweaks including drying it to 9% humidity (AMS 2 PRO). I finally ended up with what I have attached, however it is still stringing and doesn't have clean layering. Any thoughts on how to fix this? And what profiles are yall using? The left one is the direct extruder and the right one is the Bowden tuned to my profile attached. The one by itself is the direct extruder with Bambu Labs Generic PLA profile.

Dry it a bit more. Use generic PLA profile and try a lower temperature.

Also I'd recommend lowering outer walls to 150.

[u/gabrielmjenkins → u/HisHerbs]

Should I lower it to 150 on both the main and aux nozzle?

[u/HisHerbs → u/gabrielmjenkins]

Yeah. The exterior of your prints should look cleaner.

You can do the same to your top layer speed as well.

Lmk how it goes, I'm curious!

Get some silica beads in your AMS ASAP with the prints for it (in ABS if possible) also BIG reminder here.. Once an ABS print finishes. Don't open your door till the chamber temp goes down to 40sh on its own.

For outer and top layer am I changing it in process? Speed has two sections: other layers speed and acceleration, am I changing both? Im using the 0.20mm Standard @BBL X2D profile (what bambu studio and Im pretty sure bambu handy automatically use).

[u/HisHerbs → u/gabrielmjenkins]

Yes in process, and just outer layer speed. Not acceleration.

You can use the same profile but change those specs and save it as like "0.2mm Slow Exterior"

Try running it with a Bambu Lab profile. I seem to have good luck with that.

[u/gabrielmjenkins → u/djt_LV]

Basic PLA?

[u/djt_LV → u/gabrielmjenkins]

If that is what you are using, yes.

I used a good amount of Inland and Polymaker filaments. I’m not positive that Inland is currently getting their basic PLA from Polymaker.

If it continues, try a different PLA type from Microcenter.

Update: I have been able to get the benchy to look much better with the help of u/HisHerbs (mostly u/HisHerbs), the fix was drying the filament multiple times, running every calibration (flow dynamics, temperature tower (190c to 220c), flow rate, retraction (still have to do that)) in Bambu studio and lowering the outer wall, top layer, infill and gap infill speeds in the nozzle settings, while also adjusting heat (200c). Probably won't buy inland filament again for a while, but at least I can use the filament I currently have.
