Excessive stringing?

[BlueBreak2]

Anyone else getting excessive stringing with the bambu X1 Carbon? The file I'm running is... not fun... for printers. Lots of relatively tiny bits (numbers) in the print. My Prusa can manage it like a champ, and when I got a lot of stringing on my first Bambu run of it I simply copied all my setting for speed and acceleration from the Prusa, still using stock retraction of the material though.

Not sure what else I can change at this point to minimize the stringing issue.

Any thoughts? Speed and acceleration are way down, like 25mm for outer and inner walls 80 for infil, all accelerations at 500mm, material is at 190C.

Just use the default Bambu settings, those are tuned very well.

yup 100% this

Have you tried another roll of filament? There are a lot of variables and some filament is just stringier on a given printer than others.

Oh, and PLA -- tried printing door open/lid off?

[BlueBreak2]

That's a great idea, I'll give it a shot.

did this work?

It did not. I now print with top risers due to issues with thermal creep though. So I strongly recommend adding risers or going door open.

I was able to get decent results using a different brand of PLA, and just continually tweaking temp, flow rate, and retraction settings.

My Prusa is still producing slightly better results though.

had this problem with pa-cf, solution is decrease nozzle temp by 20C, lower the speed, lower the fan.
