I am tired of having to look at the diagnostics screen to see if I have probe continuity before running auto zero. I did modify the screen to add a digitize led by the auto tool zero button. Still would like a LED at the router so I don't have to look at the computer at all. How would I configure the probe input to turn on an output that I could drive the LED with.

you can not configurate this.

you have to use a brain, or macropump for this.

I was afraid there would be no easy way to do this. I even thought that some simple circuitry that's watching the input circuit could turn on the led but I'm not savvy enough to come up with that.

ok, no Problem.

give me the Output number you want to turn on, and i give you the brain,
and the instruction, how to implenet it.

I am using Port 2, Pin 11 for my probe input and would like to use Output 4 to drive the LED. Would there be much delay from contact to the LED coming on. I am using a PMDX-126 with USB smoothstepper. Thanks for your help.

ok,
attached the brain.

-copy the file to c:\mach3\brains
-start Mach3
-goto Operator -> Brain Control
-highlite the brain DigitzeLED.brn
-set the enable hook
-press reload all

finished

then you can Switch to the diagnostic sceen, and watch output4

While waiting for your file I decided to delve into brains myself. I had some Boolean logic from school and the only difference between
yours and mine was you used a pass through and I used an immediate compare > 0. They both work fine. Thanks for inspiring me to
learn. 40 below C hear last night. Hope your in better weather. 

nice to hear, you got it working.

btw it is a bit wormer here, but also -5°C.
