aren't you supposed to approach the home switches slowly when
homing? i thought homing went close and then did a slow back and
forth to set the home accurately?

For a small wood router, I dont think so.
For home switches, or something truly accurate, or fast,
yes.
An example, for illustration:
Running at 100 mm /sec, a 0.05 sec delay is 5 mm in
movement.
6 m/min or 100 mm/sec is not always very fast, today.
Iirc probing, limits and spindle index are the critical
ones, and run
under 0.5 ms delays in the ring zero layer.
(at 25.000 Hz, the lowest speed, max delay would be 0.4
ms, by my math).
Faster with hardware boards.
CSMIO runs at 4 Mhz, Pokeys at 25 kHz-125 kHz on motion
engine, not sure
on internals.
