The launch of linuxcnc on the pi is without any motor power until the F2
button is pushed. So at launch time I get messages about the z drive
being tripped.
So I need a 1 or 2 second delay before that bit is sent on thru, but
instant

I wasn't asking how long. I was asking what

Greetings all;
The launch of linuxcnc on the pi is without any motor power until the F2
button is pushed. So at launch time I get messages about the z drive
being tripped.
So I need a 1 or 2 second delay before that bit is sent on thru, but
instant transmission once timed out, giving the
