Looks like it! I had initially discounted the possibility due to the newness of the filament but it is pretty much the only thing left I guess. Thanks!

Thanks! I had printed a temp and retraction tower when I first got the printer and used those to get to 190deg 4.5mm@40mm/s. However from the other comments it looks like wet filament might be the issue.

Thanks! I had, used the pressure advance tower from the klipper wiki. It did help with bulging corners a bit at 0.250s.

I haven’t shown them, but I did print a temp tower and retraction tower when I first got the printer, which is how I got my initial 190deg, 4.5mm@40mm/s settings and those worked until I flashed Klipper. Now it seems that flashing may correlate with the filament having gotten wet.

The pla being wet is probably the only real possibility left at this point. I’m going to try and dry it today, thanks!

I haven’t yet! I’ll look up how to dry it, thanks!

Thanks! I have it on, but already at 0.2. I did try a print with it disabled and made no perceivable difference.
