Maximum Volumetric Speed Test

In the slicer, use the spiral function and set the cooling to 100% and the volumetric velocity to 99 mm/s.

Change the speed every few layers with the command M220 S and after the S write the speed percentage of the first set speed (example: if the initial speed is 30mm/s, to make it go to 60mm/s it is necessary to enter M220 S200).

In the M220 command if you write a speed percentage of 1000 or more it doesn't read it well, so write 999 if you need it.
