I am using two inputs. One for x++ and x-- with switches in series and the other for the y axis. The x ++ and y ++ limits double as home switches. The problem is when I home the y axis hits the limit and stops then the x axis does the same. I then trip on a limit switch triggered. Neither axis comes off the switch. Second problem is limit overide does not work. When I hit the switch the red led blinks and goes out. The autolimit over ride does not work. The green led comes on but nothing happens. I am tripping on a logic high signal. The machine operates fine when cutting.

Have you set a denounce? Sounds like you need to have about 1500 to start with

What is a denounce and how do I set it?

You set this under the General configs and I think it is in the upper right

There it is!

The documentation should be updated to reflect this.... according to the PDF on the website where is a "logic" config screen.

A side question... should an optical switch need debouncing?

Thanks!

Yes if there is any mechanical bounce at all in the system the computer will pick it up...

That did the trick. Thanks a lot for the help.
