Now that I figured out how to connect panel buttons to EMC and to
specify what to do when they are pressed, etc. I have coolant working
the way I want.

So now is the time to move on to more panel controls.

I have two buttons on my mill called (in the schematic) CYCLE START
and CYCLE STOP. I want to know what they mean exactly. I can make them
mean anything I want, but I want to do the right thing. This is a
little bit of a reality check.

I think that CYCLE START is like a play button, and CYCLE STOP is like
a pause button.

If I press CYCLE STOP, I want motion, spindle and coolant to
stop. Then I could vacuum chips, measure something, etc. If I press
CYCLE START, I want spindle to restart, coolant to start flowing, and
motion to resume. I am a little fuzzy on this, like how can EMC
remember that coolant was running before, for example. I guess that
pressing cycle stop twice could mean end of program and return to
manual mode.

Any comments?
