I have done a bunch of searches and no answers that work.
I have installed a external button to jog X++ and after being pushed 1 time it just keeps running
I have tried several different ways using the following.
Brains using Jog++ for X
OEM Triggers using Code 307
Input 1 with hotkeys
Nothing works to keep it from running away
Standard hotkeys using keyboard right arrow works perfect.

It seems like it would be something very simple, but I cant figure it out.

Thank in advance.

Momentary buttons are designed to send a signal only while pressed, and stop when released. If your button is toggle, it might stay "on" after being pressed, causing continuous movement. Make sure the button is momentary, so it stops sending a signal when released. 

Yes, When I go into the diagnostics you can see the light flash once for a split second.
