y axis moves randomly with arrow keys
« on: April 25, 2012, 05:25:07 PM »
Just replaced my computer.  Configure evertything.  All seems to work, except when I press the arrow keys for the y axis, the direction is random. 
Push the left key and it moves left.  Push the same key agian ang it moves right.  Both the left and right keys do this.  There seems to be no pattern to it.  Any clue?

Either a loose/broken Direction wire or something configured wrong in your xml.
If you attach your xml I can look at that.

Dont see anything wrong in the xml so I would say its most likely a hardware problem. As said earlier could be a loose or broken direction wire or possibly even a keyboard problem. To check the to see if its the keyboard you could jog from the Flyout screen with your mouse, just press Tab to get that screen.

It did the same thing on the flyout window.

Then you need to check your wiring, if you have a voltmeter you can start the checking direct at the parallel port by connecting the meter to the Dir pin for that axis and a Gnd pin then jog one way then the other, if that is OK then start checking further out.
