Default Big triumph, HOME SWITCHES WORK AND MACHINE HOMES

Finally common sense triumphed over laziness.

I found out all the home switch wiring. The home switches had a common
65 and signals 94, 95, 96 for X, Y and Z.

Wired and typed various **** into INI files, and after a lot of
confusion, all axes now home to limit switches and to index pulse.

They also do it relatively quickly. (approaching home slowly
does not work, as the switch bounces and confuses EMC).


There should be a debounce interval parameter in there somewhere that
you can set to overcome switch bounce.


If I am fast enough in my initial move, bounce is not a problem any more.

What happens is that if I approach home slowly, the home switch
triggers, but since the table stops instantly, it untriggers. If the
table moves fast, it takes it some distance to stop (1mm?) and by that
time, the switch is fully actuated. Homing fast is what I want,
anyway.

The question I have is how fast should I be in my index-finding move
(latching move).
