Problems with PLA Benchy hull

Bambu Lab P1 Series Troubleshooting
1

Hello,

I just got a new P1S Combo and noticed something weird. PLA Matte Black and PLA Green print perfect benchys. But PLA Silk NeonCity and PLA Blue create a strange dent in the front hull of my benchys.

Have a look:

[Album] First Benchys on my P1S with AMS

What could be the problem? All filaments are brand new and from BambuLab.

Kind regards,
Jan

Do you change the default settings when you switch filaments and do you use the SD card? For some reason when I first got the p1s when I printed from the sd card some of the layers would get messed up if I changed the settings from default, similar to yours. This did not happen when printing from cloud. For me, the problem fixed itself over time. Do you print from the cloud or SD card? I switched to cloud.

Did you find a fix for this?

I get the same look with some filaments, especially when printing the benchy at over 400mm/s.
Check the preview and you find the printer slows down for this area.
Either use a print speed that is lower overall, disable the slowing down options or try to tweak the settings a a bit.
What you have on the hull is just physics working as planned.
