Homing speed to 40mm/s (#358)

thomasfjen · web-flow · commit d8425f9a4c25 · 2024-08-26T08:30:23.000-05:00
Bump up sensorless homing speed to 40mm/s as the TMC2209 documentation says: "Very low motor velocities (for many motors
well below one revolution per second) generate low back EMF and make the measurement unstable
and dependent on motor and IC production stray"

With 40mm/s it will result to 1 rotation per second,. currently it's just half a rotation per second.
