It was 100% stock hardware and Bambu PLA Basic. I set it from 1 to 72 mm³/s in steps of 1 IIRC, although it would actually top out at 24.76 mm³/s because that is 500 mm/s which is a hardware limit.
Edit: It was more likely 1 to 36 mm³/s in steps of 0.5
Edit2: I may have used something like this to increase the temperature with speed. Can’t remember.
