Work with probe

Hi,
All probe masterminds.
I am using qtdragon and love it but I have another stupid question.
I have touch probe connected to probe-in that is all good.

What pin do I connect the tool sensor?

I believe that I have my 3D probe and Tool Setter connected to the same hal pin through an "or" component.. The 3D Probe and TS are connected to different physical pins on the Mesa card.

I found this.  It might help.

SiegX3.hal

#3d Probe
net deb-probe-in debounce.2.0.in <= hm2_5i25.0.7i76.0.0.input-11-not
net probe-in debounce.2.0.out
net probe-in => or2.probe_in.in1

# Tool-Setter-Sense
net deb-toolsetter-in debounce.2.1.in <= hm2_5i25.0.7i76.0.0.input-12-not
net toolsetter-in debounce.2.1.out
net toolsetter-in => or2.probe_in.in0

custom_postgui.hal

net toolsetter-out or2.probe_in.out => motion.probe-input qtdragon.hal_led_probe

 

Right thanks it kind of makes sense but hmmm what happens when you touch off the 3d probe on tool setter?
I have not had time to wire it up and try it so just my imagination plays tricks on me I guess.

The only time I touch off on the tool setter is when I am running a program and after a tool change there is a tool in the spindle that has a zero length
in the tool table.  The zero length indicates that the tool needs to me measure and it automatically goes over to the tool setter and measures the tool. 
If tool that was just loaded into the spindle has a length > 0 in the tool table it goes directly to cutting the part.
The only time the 3D probe is in the spindle is when I just put a piece of stock in the vice and need to locate it.  I run the appropriate probe routine from the probe screen in QTDragon to get the X,Y,Z.

Ok that all make sense but how do you set the 3d probe length. It might be stupid question but it just does not click in my noggin.
because if you set Z with unknown 3d probe length the Z be all over the shop.
Or am I missing something or am too complicated.
