I print this on an x1c regularly so if might be a filament issue maybe? Or maybe try slowing it down to silent mode for those spots but this is an issue anyone has had yet so not sure what could be causing it. i also use the same threads on other designs without issue. I usually print this in regular matte pla filament. You can also re slice with a lower layer height maybe? Hopefully one of these solutions helps! I just printed again with this print profile and didn’t have an issue

I was using pla-cf for the black part. I am gonna try other colors again, cause the rest of the print was really nice. I will slow it down and see how it goes

you get it to work? threads didn’t print for me either, using Bambu pla
