Sub 20 minute Benchy - Original Prusa MK4 (alpha firmware with input shaping)

Following the speedboat race rules (such as 10% infill, 0.25 mm layer height, 2 perimeters).

This Benchy was printed with the default acceleration of 8000 mm / s2 and 200 mm/s on external perimeters. These are work-in-progress numbers since we’re still in the process of tweaking everything, so don’t take them as final and definitive values.

One important thing: with our printers, we aim to deliver great print quality, not blobs of plastic in a record amount of time. So we’d rather extend the print time by a few minutes and have nicer prints and accurate dimensions, instead of chasing every single second.
