Sorry about the late comment on this thread. New to EMC.....
Another data point for future EMC enhancements related to
feedhold/stopping/restarting a program...... On a Siemens Acramatic 2100
control (Cin-Mil vertical machining center), a "spindle stop" shuts down
all axis movement, stops the spindle and shuts down coolant. The program
is still active yet all axis can be jogged manually (i.e. to view the
part). "Spindle start" restarts the spindle and the coolant (if
previously on) without any axis movement. Holding "cycle start" returns
axis to original location at feed rate as long as "cycle start" is
depressed (releasing "cycle start" stops all movement back to the
original location). Once the original location is reached, all axis
stop. A second momentary pressing of "cycle start" continues the program
where things left off. Can EMC do something similar? If not, would it be
useful in a future version? Not a show-stopper for my current EMC
application.
P.S. Successfully recompiled EMC in simulator mode under Ubuntu Hardy.
EMC's an impressive free (as in speech, not beer) control application.
Thanks for all your hard work......Dean

A lot more got put into my question than I expected.
I dont want to do any changing or stop running the
program,
The reason I wanted this feedhold feature is lets say
you are running a tool for the first time and are coming
down near the part you could hit feedhold and look at the distance to go
and see if if there will be a crash
Now the people who think it is not necessary are people
with small/slow machines-- I have 500imp coming at the part
and a lot of iron moving.
As far as how other machines work the new Fanuc controls
can be set up to work like this:
one hit of the feedhold stops motion and shuts off the
coolant,two hits will stop the spindle but you are still
in auto mode--then one hit of the cycle start will start the
spindle the next hit of the cycle start will start movement
and the coolant.
Thanks

Would it be possible to have the coolant turn off when
I hit feed hold?(I usually hit the "p"key for feed hold)
Most of my parts require alot of coolant so I cant
see the tool at all.Should F8 do this?
If it is a pain in the rear to do I can put a switch to
do it manually.
In normal CNC controls, Feed hold stops movement, nothing more, but
other controllers then allow you to do anything you like.

allow anything else.
To do anything useful, you need to note the line, stop, do whatever,
then restart from that line :(
