Seen so many people with ironing speeds at 30mm/s or something insanely slow like that so wanted to share. This is 150mm/s just crank the speed up, even my artillery hornet can handle ironing at 125mm/s, and it can't even print good at above 70mm/s lol.

Most importantly use 0.1mm line width. Flow varies a lot, this here is 25% flow but some filament needs up to 35-40%. Just try different flowrates and what works.
