Hello,
I could use some help writing a brain.
I need to output a signal to a relay.
On when Z moves down and off when it moves up.
Any suggestions would be very helpful.
Thank you.
Mario

something like this might work

Sorry I missed your reply. My email isn't forwarding replies.
Thank you for your interest in my problem (which is mine as you say).
How do I install this brain into the brain folder?
It is a PNG file.
It looks more complicated than I first thought but would love to try it.
Thank you again,
Mario

ok, i am sorry to have this brain file thrown away.

you have to rebuild it of the screenshot.

it you have Trouble, let me know, then i will do a new brain file

Here is, recreated

Hello,
I tried to write it in the brain editor but just do not have enough experience at this time. Your help would be very much appreciated.
(Love your cars!)

Okay, getting close.
The Z down movement turns on the relay.
But when the z reverses upwards, it stays on.
Could you please take a look,
Thank you again,
Mario

i have tested the brain here, it works fine.

Another possibility you may wish to consider…

The Z axis Direction Pin state is modal, it will have one state when (and after) the Z axis has moved in one direction and the opposite state when (and after) the Z axis has moved in the other direction. The Z axis Direction Pin could then be used to switch an Output# ON or OFF without using Brains.

Tweakie.

Of course, you tested it before sending. It was late and I didn't see I had another brain enabled that kept the relay on.
So I was a man with 2 brains! 
Thank you for all your help.
Also, I would like to try the Tweekie approach.
If I use pin 3 for Z direction and have pin 3 OUTPUT # 1, pressing Z down should turn on the relay.
But it doesn't so I must have missed something.
