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 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.
