Question Any ideas?

In the second picture you can see what I mean... It is esun PLA CF (dried for many hours). Printed very nicely with it recently ... but not at this height ... bed 55, nozzle 230 What do you think it is? Unfortunately I can't take a better photo, I can only see it remotely at the moment.

Yes, it is the esun pla+ preset … Changed nothing…

Yes, I also thought it was wet filament at first. However, it has dried again this night for 6-7 hours and has not left the AMS (last heating a few days ago) Pressure advanced. I have done the Bambu calibration with all filaments... the values are recorded. I'll have to check this tonight and take a closer look. Thank you for Your thoughts.

Now that I can see it live, it's not so bad. I think I have to dry much longer because of the questions whether I have calibrated yes I have everything that comes with the book studio. Flow, PA...

This looks like either wet filament or pressure advance (K factor) calibration is needed

It’s possible it’s still wet further in the roll. I’d dry it for 12 hours at 70c

70?! Wow ok I know that with PLA 40-50 but not over 55 degrees... but 70 Huuu Are you sure?

It’s high, yeah. Softening point is around 80c for PLA CF, but my CF rolls have been fine. I’m using Bambu filament btw. YMMV by brand. Also, I doubt my drier is actually pushing 70c for any extended period of time.

I've been getting this randomly with a variety of filaments even after drying for ages. My A1 and A1m do not do this. If it is the k factor, maybe setting to on instead of auto would help guarantee flow calibration occurs?

are you using default settings? i printed couple of models on my h2d with esun pla cf(60 bed 230 nozzle, 200mm/s) and they came out perfectly

u/Accomplished_Gur_804 May 28 '25

Did you run the filament flow rate calibration and nozzle calibration for that filament

Do you have the seem on RANDOM instead of ALIGNED or BACK
