My #SpeedBenchy following the rules.
As stated in the video, I want to stress that this isn't the fastest I could go. In fact, I managed to push up to the 11 minutes mark (still wondering how some monsters did 5 minutes or so :P ) but the quality outcome was bad. Instead, I wanted to do a fast Benchy while retaining a good quality and I think this is my best compromise.
Klipper was of course my best friend, thanks to accelerometer-driven input shaping and pressure advance. My other best friend was calibration of every parameter of the printer and the slicer. Calibrate your printers folks!
